4 Introduction is the name for a family of drive systems with variable-speed motor. This product information provides a brief overview of these systems. Since the pulse withstand voltage of the insulation is of particular importance for the motors of variable-speed drive systems, information is also given on the electric strength of VEM insulation systems. As examples for the countless possible applications of, drive systems with 2- to 6-pole motors in standard versions for square-law and constant torque characteristics have been summarised in tables, together with corresponding cable recommendations. Motors with standard insulation VEM energy-saving motors are always suitable for operation on a frequency converter, irrespective of their efficiency classification. Assuming that the service life of the winding insulation on converter-fed motors can be equated to that on mains-fed motors, the pulse voltages at the terminals must not exceed 1,350 V on motors with standard insulation, in accordance with IEC/TS (VDE 0530 Part 17): In case of pulse voltage rise times of less than of voltage rise du/dt. Otherwise, the service life of the motor insulation will be shortened in line with the pulse voltage overshoot. The technical data of the VEM motors can be taken from the main or basic catalogue. An electronic catalogue is available online at our website Û LL V u (t 1 ) Δu = u (t 1 ) - u (t 0 ) u 100% 90% t a 0 0 0,2 0,4 0,6 0,8 1 1,2 1,4 t a µs Fig. 1: Limit characteristic curve of the permissible pulse voltage Û LL at the motor terminals, as dependent on the rise time t a [IEC/TS (VDE 0530 Part 17):2004] u (t 0 ) 10% 0% Fig. 2: Definition of the rise time t a of the voltage at the motor terminals t 0 t 1 t 0.8 μs at the motor terminals, the permissible pulse voltage is reduced as shown in Fig. 1. If short rise times lead to exceeding of the permissible pulse voltages, filters must be incorporated at the converter output to extend the rise times and thus to reduce the rate VEM recommends the appointment of a responsible system manager when planning electric drive systems for mains voltages > 420 V or for outputs from approx Only an experienced drive specialist is able to guarantee optimum system configuration. Motors with reinforced winding insulation Drive systems which are operated on mains voltages above 420 V may necessitate motors with reinforced winding insulation. Insulation with an enhanced pulse withstand voltage is required especially where motors are connected to a converter without filter by way of a long cable or else operate frequently in generator mode. For such applications, VEM has developed motors with particularly high electric strength. These motors must always be chosen where motors are fed via a converter with an input voltage above 420 V and where the level of the pulse voltages to be expected at the motor terminals is unknown.

5 Motors for use on a frequency converter without filter up to 500 V Limit curve A Motors of the design series IE1-KU.R and IE2-WU.R are provided with reinforced winding insulation, which enables the motors to be operated on converters for mains voltages up to 500 V without filter. From IEC size 315, insulated bearings are used on the non-drive side as standard. The KU.R series is well proven after many years of worldwide use. It is based on an insulation system in which the main components e.g. slot insulation, grade 2/class 200 winding wire and high-quality impregnation resin are carefully matched. The windings are double vacuumimpregnated. The PTC thermistors are similarly matched to the higher electric strength of the motors. Provided the pulse voltages are limited to the maximum permissible values according to limit curve A (see Fig. 3), the motors of the design series IE1-KU.R and IE2-WU.R are also very well suited to operation on 690 V converters. The benefits include: Favourable cost Motor size = Standard size = Standard output Reduction of harmonic loads on motor cables EMI emissions and bearing currents. Motors of the IE1-KU.R series are designed for operation on a converter. The series is based on motors which comply with efficiency class IE1 in mains operation. The IE2-WU.R series is based on motors which comply with efficiency class IE2 in mains operation. These motors are especially suitable also for applications where an increased thermal reserve is desirable. Upon request, it is possible to supply motors for efficiency class IE3 with reinforced winding insulation. Motors for use on a frequency converter without filter up to 690 V Limit curve B For motors of the design series KV.R, VEM uses insulation materials of very high quality to enable operation on converters for output voltages up to 690 V without additional output circuitry. This insulation system is designed to withstand pulse voltages in accordance with limit curve B (Fig. 3) at the motor terminals. The basis of the insulation system is a mica-insulated winding wire. The greater volume of the insulation material, however, reduces the active slot space. In the versions KV1R, KV0R and KV2R, the output is thus lower than that of a motor of the same size from the basic series. With the KV4R version, on the other hand, the IEC/DIN output assignments are observed. The motors are designed to thermal class 155 [F]. From IEC size 315, they are provided with insulated bearings on the non-drive side as standard. The motors are available from size 132 S as standard. Motors for efficiency classes IE2 and IE3 can be supplied upon request. Fig. 4: Stator of the KV.R series, before impregnation Draft IEC /FDIS In the foreseeable future, motor insulation systems are to be assigned to stress categories. Draft standard IEC /FDIS plans the introduction of a so-called Impulse Voltage Insulation Class (IVIC). The phase-to-phase insulation, phase-to-earth insulation and turn-to-turn insulation of an insulation system must be classified individually according to the following stress categories: A Low stress B Medium stress C High stress D Extreme stress The stress categories are to be specified in the motor documentation and indicated on the rating plate. The IVIC classification could be given as follows, for example: IVIC C/D/C Phase-to-phase insulation: C (high stress) Phase-to-earth insulation: D (extreme stress) Turn-to-turn insulation: C (high stress) VEM will provide information on the classifications of its insulation systems as soon as the corresponding standards become effective. Mechanical limit speeds In case of operation at frequencies above 60 Hz, the permissible limit speeds (see main catalogue) must be observed. The high-speed option is available specifically for standard motors which are to be operated at high speeds. As the relubrication interval for the bearings is shortened with increasing speed, VEM recommends the incorporation of a relubrication systems from IEC size 160, depending on the duration of operation. A separate cooling fan may be expedient to reduce running noise. 5
