INTRO TO MOTORS SLO-SYN Introduction to Step Motors Step motors are capable of very precise positioning without the use of complicated and expensive feedback devices, although feedback systems may be incorporated into step motor systems if position comparison is desired. Because of the simplified control needs and the freedom from expensive feedback requirements, step motors are viable alternatives to pneumatic, hydraulic and servo motor systems.step position loads by operating in discrete increments, or steps, unlike other devices that operate at constant speeds. The stepping action is accomplished by switching the power to the motor windings so that the motor phases are energized in a specific sequence. Typical Applications Automation and inspection Conveyor Transfer Cut-to-length metal, plastic, fabric, etc. Industrial HVAC Material Handling Medical equipment Office peripheral equipment Packaging systems Pick-and-place applications Printing systems Robotics Semiconductor manufacturing XYZ Applications DC 4

Features of a High Torque Step Motor Brushless Robust Design Ground Screw Included Rugged Square-Frame Construction Permanent Magnet Rotor Sizing and Selection Software for Superior Electric SLO-SYN Products 33 Stainless Steel Shaft Double Shielded Ball Bearings INTRO TO MOTORS How to Select a Stepper Motor Successful application of a step motor requires careful selection of the proper step motor drive and control as well as the correct step motor. Since step motor systems are often used as ultra high performance positioning systems or motion controls, selection of the optimum motor/drive combination is of prime importance. The first step in the selection process is to decide the kind of system to use. Examples include Cylinder/Rod (solid or hollow), Lead Screw, Rack and Pinion, Disc/Pulley, Conveyer or Nip Rollers. A complete load analysis will be required to determine the correct motor size and the amount of torque needed to drive the load. Then it is necessary to determine which motor will best suit the application: Stepper Motor or Servo Motor. CAMAS software for Windows is a menu driven program which will make all these calculations for you. CAMAS is free software which is available upon request. DC 5

GEARHEADS SLO-S O-SYN Gearheads Many applications need a higher torque or a smaller step angle than is possible by directly driving the load from the motor shaft. An ideal way to satisfy these requirements is by using a motor that has an integrally mounted gearhead. SLO-SYN DCGearheads are available in precision NEMA and Planetary models to meet the need for speed reduction without the problems associated with belts or pulleys. The wide range of available ratios assures a design solution for virtually any Motor with NEMA Gearhead application. The Gearheads can be supplied as a complete assembly with the Gearhead already NEMA Gearhead Kit mounted to a SLO-SYN motor, or as a kit for mounting to an existing motor. Both NEMA and Planetary types are offered with a clamp-on pinion for the motor shaft or with a pinion designed to Motor with NEMA Gearhead be pinned to the shaft for positive, permanent mounting.

SLO-S O-SYN DC STEP MOTOR ORS - APPLICATION ASSISTANCE ANCE Sizing and Selection Software for Superior Electric SLO-SYN Products How to Select a Stepper Motor Successful application of a step motor requires careful selection of the proper step motor drive and control as well as the correct step motor. Since step motor systems are often used as ultra high performance positioning systems or motion controls, selection of the optimum motor/drive combination is of prime importance. The first step in the selection process is to decide the kind of system to use. Examples include Cylinder/Rod (solid or hollow), Lead Screw, Rack and Pinion, Disc/Pulley, Conveyer or Nip Rollers. A complete load analysis will be required to determine the correct motor size and the amount of torque needed to drive the load. Then it is necessary to determine which motor will best suit the application: Stepper Motor or Servo Motor. CAMAS software for Windows is a menu driven program which will make all these calculations for you. CAMAS is free software which is available upon request. CAMAS APPLICATION ASSISTANCE DC 53

Underwriters Laboratories Recognition & Canadian Standards Association Certification and CENELEC Certification All M6, KM6 and M9, KM9 Series motors are recognized by UL, UL#E31544 KM6 and KM9 Series motors carry the CE mark Most standard motors are listed by Canadian Standards Association, including all M6 and M9 Series Motors Motors in other series which meet UL requirements are identified with letter U suffix or are provided with a UL logo. Most standard motors, as well as double end motors, are eligible Comparison of Servomotors versus DC Step Motors Too often, when a motion control system is being specified, the designer automatically assumes that a servomotor system must be used. The truth is that, in many cases, a well designed step motor system will perform the same function as well, and at lower cost. The following comparison of the outstanding characteristics of the two types of motors outlines some of the advantages of step motors for motion control. Servomotor Characteristics Require complex, expensive control systems Position sensing devices needed for feedback to control Relatively low torque for size Thermally inefficient Control system must be tuned to load; must be retuned if load is changed Brushes on DC servomotors subject to wear SLO-SYN DC Step Motor Characteristics Relatively inexpensive Can be operated open-loop (no position feedback required) Noncumulative step error Simple control electronics can be used Brushless construction aids reliability Maintenance free Will not be damaged if stalled High torque for size Maintain position when at rest Call Superior Electric for a copy of Superior Motion Control Application Solutions, a user s guide to applying step motors and controls. Construction of DC Step Motors A SLO-SYN Step Motor is a brushless DC motor consisting of a rotor and a stator assembly. The illustration shows the internal construction and tooth alignment of the motor. A certain number of teeth, evenly spaced around the entire diameter, provide the incremental angular rotation that results in mechanical motion. SLO-SYN steps motors are constructed with a 48-5 or a 52-5 tooth pitch configuration. The second number, 5, refers to the number of teeth on the rotor. The 5 teeth, combined with the winding configuration and permanent magnet construction, deliver a 1.8 step angle. Both configurations have a slightly different tooth pitch on the stator (48 or 52) to provide smoother operation and softer step-to-step motion with less resonance or mechanical instability at low speed. The 52 tooth stator design is used in the new KM6 and KM9 motors to provide extra torque. Superior Electric held the original patent on the 48-5 design. DC 64
