Description

The basis is the standard series with a low-noise cast iron frame, a class 155 (F) winding with thermal margin and optional class 180 (H). The design complies with DIN EN 60034 (IEC 60072), and mounting dimensions and power allocation follow DIN 42673, 42677 or the progressive series. Protection degree is IP55, optionally IP56 and IP65 per EN 60034-5, mounting IM B3, B35, B5, B14, B34 per EN 60034-7, cooling IC411, IC416 or IC410 per EN 60034-6. Altitude above sea level is up to 1000 m, coolant temperature −20…+40 °C. The terminal box is on top, on the right or on the left, and an RFID transponder iID 2000 is optional. The motors are fitted with spring-applied brakes of third-party manufacturers of types BFK457, BFK458, ROBA-stop, KFB, SFB, NFF, COMBISTOP 08, 4 BZFM and BZFM V7.

How to choose

The brake is selected by torque, coil supply voltage and the options needed, in particular manual release and wear monitoring. Brake types are listed in the specification, and each has its own manual. The motor is chosen by power in the range 0.12–500 kW and speed from 3000 to 500 rpm, lower on request. The efficiency class is unclassified, IE1, IE2 (taking VO(EC) 640/2009 into account) or IE3. If a brake is not needed, there is the basic IEC-Normmotoren series, and for variable-speed machines a frequency converter is needed.
