Torque Mors Direct Drive Servo Mors

Direct Drive Servomors Direct Drive technology has recently become more and more commonplace in machine and facry aumation. Parker s Electromechanical Division has been well known for many years as a specialist in direct drive technology. Parker offers various kinds of rque mor, in ready run and kit form, as well as linear mors. These mors are ideal for solutions in printing machines, bending machines or machine ols which require extremely smooth rotation, especially at very low speed, and very high accuracy. Frequently there is also a requirement for a hollow shaft. Designed with the aim of addressing new industrial needs, Parker has developed the ST range of low inertia mors for Direct Drive providing acceleration rates up 2 rad/s ². The ST range is available in three diameters, 15 mm, 19 mm and 3 mm, with either hollow or solid shafts of 6 mm till 75 mm diameter respectively. Rated rques range from 15 Nm 235 Nm in natural convection, with peak rques from 55 Nm 1161 Nm. The mors can reach rated speeds of 2 min -1 till 15 min -1 according winding type and provide exceptional speed regulation at low speed. The 15 mm, 19 mm and 3 mm ST ranges offer outstanding performance with a continuous rque-weight ratio up 3.7 Nm/kg and a peak rque--weight ratio up 18 Nm/kg. Parker has also expanded its product portfolio with a new range of Direct Drive frameless mors. Complementary its ST range, these kit mors (star + ror) are designed be integrated within machine ols such as rotary tables and grinding heads. These applications frequently require a large-diameter hollow shaft as well as high accuracy and speed regulation. The new STK frameless mor range offers outstanding rated rque from 15 Nm 27 Nm in natural convection, and can reach 61 Nm using fluid cooling. The peak rque is 3 times higher than the rated rque (up 9 Nm) and is available up the rated speed. The large-diameter hollow shaft provides an internal clearance between 56 mm and 63 mm. Parker Direct Drive mors have been designed and industrialised with the aim of ensuring excellent performance as well as acceptable cost for users. Compax3 - Servo Drives of the Third Generation- Modern digital control technology aids the realisation of highly productive and flexible aumation solutions. It forms the basis of a stable control system and, most importantly, the precise positioning of linear actuars or other direct drive technologies. Without requiring any additional options, Compax3 supports diverse mor technologies including synchronous servo mors, linear servo mors and even rque mors. Due its inherently modular structure, the Compax3 intelligent servo drive can be employed in a wide range of industrial applications. Based on a standard version of the drive, Parker Hannifin is able offer a large number of additional PLC- and advanced technology functions for the Compax3. Direct drive is more than just a good idea! 2

Torque Mor Kit Series Frameless Brushless Torque Mors The frameless Kit Mors STK and K - Series are the ideal solution for machine designs that require high performance in small spaces. Kit Mors allow for direct integration with a mechanical transmission device, eliminating parts that add size, weight and complexity. Use of Frameless Kit Mors results in a smaller, more reliable mor package. The STK and K - Series support applications need a large-diameter hollow shaft with ring-type technology. K Series www.parker-eme.com/kseries Direct Drive Direct drive mors as STK and K - Series mors provide higher dynamic stiffness by eliminating the compliance of shaft attachments. Direct drive mor construction gives equipment designers the advantages of lowered costs, increased reliability and improved performance. Frameless Kit Mors are the most cost effective direct drive mor solutions available. Kit mors save space in applications because the couplings, mor mounting brackets and extra bearings you would find in coupled drive construction are eliminated. Main characteristics STK Kit Mors www.parker-eme.com/stk Continuous rque from. Nm 27 Nm with natural convection (according size), and up 61 Nm with fluid cooling. A wide range of external diameters from 32 mm 8 mm. Internal diameters from 15 mm 63 mm. Various windings available from 3 min -1 15 min -1 according size. Electromagnetic and thermal optimisation has permitted high rque-weight ratios be achieved with natural convection and even higher with fluid cooling. The Parker STK and K - Series range of frameless mors addresses very demanding industrial applications, not only in terms of performance (dynamic performance, rque capability and precise rotation at low speed) but also in terms of cost. Particular attention has therefore been paid in the design the combination of technical and economic optimisation. Parker also addresses direct drive applications up 3 kw in natural convection at speeds up 15 min -1 for STK and up 5 min -1 for K - Series. The various speed ratings are achieved by having a range of available windings. 1

K-Series www.parker-eme.com/kseries The Frameless Kit mors are ideal solutions for machine designs that require high performance in small spaces. The kit mor approach allows for direct integration with a mechanical transmission device, eliminating parts that add size and complexity. The use of frameless mors results in a smaller, more reliable mor package. Pre-installed integral commutation board is pre-aligned for easy assembly. Rare earth magnets provide high flux in a small volume and high resistance thermal demagnetizing. Machined grooves securely lock magnets ror and ensure optimized radial location. Class H insulation for high temperature operation (up 155 ºC) meeting UL approved requirements. High density copper winding for low thermal resistance and consistent performance across all mors. Minimized end turns maximize performance and minimize mor size. Skewed laminations with odd slot counts reduce cogging for precise rotary motion with drastically reduced rque ripple even at low speeds.

Winding Selection The selection of a particular frame size and winding for an application is dependent on: Volume (diameter and length) requirement Power (rque and speed) requirement Voltage and current available or required The first two items are dependent on the load and performance specifications of the application. They result in the selection of aparticular frame size and stack length. The winding be used will then be determined by voltage and current available or required. Voltage: The bus voltage and maximum speed will determine the required voltage constant (KE). Current: The maximum load and acceleration will determine the amount of current required, determined by the rque constant (KT) associated with the selected voltage constant. Example: Assume a requirement of 1 min -1 at.35 Nm. If a mor with a particular winding having KE = 18.2 V/1 min -1 and KT =.17 Nm/A is chosen, it will now require a voltage (BEMF) of 18 V and current of 2 A. Note: KE and KT are directly proportional each other. Increasing KE will also increase KT. Decreasing KE will also decrease KT. The result is that as the voltage requirement changes, the current requirement changes inversely. Parker has a range of 27 windings available for each frame size and stack length, providing for virtually any practical combination of voltage and current required for your application. The following pages show just a small representative sample of speed/ rque curves for each of the 1 frame sizes available.

STK Series Frameless brushless rque mor as kit version www.parker-eme.com/stk With the STK range, Parker offers a solution for direct drive applications. Examples include: Applications needing tal integration of the mor within the servomechanism due volume and/or weight considerations Applications needing a large-diameter hollow shaft demanding a ring-type technology Main characteristics Continuous rque from 1 27 Nm with natural convection (according size), and up 61 Nm with fluid cooling. Six external diameters from 15 8 mm. Internal diameters from 56 63 mm. -1 Various windings available from 3 15 min according size. Parker s STK range of permanent magnet brushless mors has been specially designed for direct drive (without a gearbox), particularly in applications needing very low volume and weight in relation the rque and power requirements. Electromagnetic and thermal optimisation has permitted continuous rque--weight ratios up 1 Nm/kg be achieved with natural convection and up 31 Nm/kg with fluid cooling. The Parker STK range of frameless mors addresses very demanding industrial applications, not only in terms Mor Constitution STATOR: this consists of iron laminations incorporating the windings and attached the external aluminium housing. The windings are encapsulated in resin. The housing may incoporate a cooling circuit when fluid cooling is required. Thermal protection: Type KTY8 and PTC - embedded in the winding. Winding class: H. Natural convection The star is the source of copper losses as well as hysteresis and eddy current losses. It is necessary take this in account when incorporating the mor. Here are the main points be taken in consideration: Continuous rque ratings are indicated for a copper temperature rise of 12 C for housings in contact with ambient air, or in contact over the full peripheral area with a metal component in contact with ambient air. In addition, the mor housing must be fixed on a metal flange having an area equal at least twice the housing area. of performance (dynamic performance, rque capability and precise rotation at low speed) but also in terms of cost. Particular attention has therefore been paid in the design the combination of technical and economic optimisation. Industrial users can sometimes be dissatisfied with direct drive servo systems because they are frequently based on rque mors with limited power and speed capability. With the STK range, Parker set out counter this objection by creating mors that could not only satisfy lowspeed applications with their associated speed regulation, but could also address direct drive applications up 3 kw in natural convection at speeds up 15 min -1. The various speed ratings are achieved by having a range of available windings. Some of these are illustrated in the catalogue, but numerous winding variations are possible allow the drive system be optimised. Power cable: class 6 with shielded wires for power. ROTOR: rare earth magnets protected against corrosion are attached the periphery of a magnetic iron ring. Star and ror mounting: STK armatures and rors can be optionally shipped mounted on a centering and positioning flange which eliminates the need mount and centre the ror inside the star. For example, for a mm diameter mor, the minimum flange area will be equal π x. 2x 2 =.25 m 2 Avoid an enclosed environment, or if this is unavoidable, consult us for calculation of the mor derating. Be sure that the materials located in the vicinity of the mor can withstand high temperatures. If this is not the case, consult us for recommendations on derating the mor. 16

Fluid cooling To avoid overheating due environmental facrs, or achieve a higher continuous rque rating than is attainable with natural convection, it is possible use fluid cooling. Fluid cooling specifications are based on two operating points: Winding at 6 C. Maximum cooling (winding at 1 C) for obtaining the maximum continuous rque from the mor. The outside of the star is machined with a helical groove which forms a cooling circuit when the star is fitted inside an outer housing. Circular grooves at each end of the helix form input and output channels; the input and output portsin the outer housing must be axially aligned with thesegooves. Additional circular gooves at each end of the starare fitted with O-rings form a seal. Use either softened water with a glycol additive or a fluid approved for closed-circuit cooling in order minimise the risk of corrosion and deposits. Position sensor Parker STK frameless mors have been designed for minimum rque harmonics when they are driven by a sinusoidal brushless drive. Various positioning sensors are available, and the drive may use types of positioning interface: Resolver: In a high-quality resolver (e.g. Parker RES FC6 72 32), the accuracy is limited around 1 arc-minute. In most of the resolvers currently available, accuracy is of the order of several arc-minutes. It is necessary check whether the desired positioning accuracy is compatible with the resolver accuracy. On another hand, resolvers can limit the range of applications when they obstruct a hollow shaft. Finally, resolvers are available with resolutions up several hundred thousand counts per revolution, but such a high resolution is generally not useable because it is not compatible with the accuracy of the measurement system. TTL encoder or TTL optical scale: TTL encoders usually have a limited resolution (from 5 5 counts/rev.). However it is possible find encoders with hollow shafts up 5 mm internal diameter and with resolutions between 15 and 2 counts/rev. (multiplied by after decoding). The best solution in terms of resolution and accuracy is generally offered by optical scales with pitches from.5 5 µm that can be attached a hollow hub with the appropriate diameter. They can offer resolutions of 1 million counts/rev or more depending on the diameter. The associated read heads have a maximum operating frequency which limits the speed for a given resolution. Absolute encoders: Absolute encoders offer the characteristics described for TTL or Sin-Cos encoders without the need for a startup sequence for phase commutation (see following paragraph). Also they avoid the need for a homing sequence locate the axis zero point. SinCos encoder or SinCos scales: These encoders and scales are very widely used. The same limitations as previously mentioned apply these devices. However, the advantage of this technology lies in the possibility of interpolating the sinusoidal output using an appropriate drive interface. Thus an encoder with 12 sinewaves per revolution used with x1 interpolation will produce one million counts/rev. The Sin-Cos optical scale has the advantage of producing high resolution either directly or by internal drive interpolation, gether with an unrestricted hollow shaft, since it may be attached an appropriate diameter hub. Phase commutation Permanent magnet synchronous mors require a constant phase angle between the rotating fields of the star and ror in order control the rque. The resolver provides the necessary phasing information and simultaneously gives the axis position (within one polar pitch). Absolute encoders also provide this phasing information, but this is not the case with incremental encoders or scales. Encoder suppliers therefore offer specific ranges for brushless mors including either: a) Three-phase commutation rectangular signals (U, V, W, /U, /V, /W) in the case of a TTL encoder; these waveforms must have the same number of cycles per revolution as the number of pole-pairs in the mor. b) Sinewave signals (1 cycle per revolution), sine and cosine, giving the absolute position within one revolution in the case of sin/cos encoders. The drive electronic interface multiplies this frequency by the number of mor pole pairs. In the case of an optical scale mounted on a hub, the information related the phasing between the star and ror fields is not known. Therefore an initialisation sequence is needed during start-up; during that sequence the ror will perform an indexing motion, or at least a small oscillation. 17

For mounting the housing, use either external the centering diameter (B) or internal centering diameters (A). For assembly lerances (perpendicularity, concentricity...), please consult us. Fluid input and output pipes must be aligned with the cable output. O-ring grooves are designed for mm diameter o-rings. Dimensions in brackets ( ) for P, LB, J and E3 are mm wider when the nominal current is greater than 72 A ( single wire outputs). 28
