For the mounting of IEC standard motors, the drive shafts were changed such that the shaft journal of the motor can be inserted directly into the bore of the gearbox drive shaft. As types VLM and SLM, they are part of our product range. The proven ATEK bevel gearbox and worm gearbox series form the basis for them. The combination of a large number of motor flanges and the insertable motor shaft journal enables the adaptation to a variety of IEC motors. 10.2.1 Motors ATEK gearbox motors are available for ratings from 0.12 to 30 kW. The bevel gearbox motors are delivered with output speeds from...

10 Gearbox motors Motor protection For the pole-changing motors, it must be ensured that the windings are protected at all speeds. If appropriate, special switches will be required. Circuit breakers In case of current-dependent motor protection, the circuit breaker must be set to the nominal current specified on the rating plate. In case of higher numbers of switching actuations, cooling temperature variations or speed control with frequency converters, the motor protection is insufficient. Complete PTC resistor protection In case of complete PTC resistor protection, 3 temperature probes will...
