Product Description

The SD-B4.180.020-01.000 permanent-field servomotor from Bosch Rexroth is characterized by high resistance to demagnetization. This motor has a peak torque that is three times the nominal rated torque. The product comprises a brushless tacho to detect the position of the rotor and for velocity feedback. This device is meant to be handled only after reading its documentation. The unit can be mounted vertically with the shaft facing upward after ensuring that there is no fluid retention around the shaft. Its connectors are made of plastic and comprise an aluminum securing ring. The motor surface may become very hot when it is in use.

This product encounters axial plus radial forces at the time of operation. The device has no built-in oil-tight bearing at the driving end. This unit encompasses a NTC thermostat with an operating temperature range of -10 °C to 145 °C. It has a N vibration quality level according to DIN ISO 2373 specifications. The motor has a brushless tacho. This product is compatible with a TC series inverter with a peak current rating of 15 A / 30 A. The device supports up to 60 N axial force on its shaft with IM V3 mounting. The unit is capable of maintaining its protection standard only if the cable glands have the minimum cable cross-sectional areas.

This servomotor should be free of a power supply connection when any installation or connection work is done. Its supporting inverter encompasses three terminals for the motor connection. The product and its tacho have live terminals due to permanent magnet excitation when the rotor is being driven. This device portrays a maximum ambient temperature of 55 °C for its braking resistors. The unit has a tacho connector with pin 12 sealed using a blanking plug so that the tacho and encoder plugs can be distinguished.
