Product Description

The Bosch Rexroth SD-B5.380.030-10.000 is a best-in-class permanent-field servomotor in the SD series. The motor is meant for inverter operation and it supports electronic commutation. Permanent magnets are present in the motor’s rotor. These magnets consist of ferrite material. A tacho and a commutation sensor are integrated into the non-driving end of the device for velocity feedback and rotor position detection. The product is an essential part of the Servodyn drive concept of Bosch Rexroth. The unit depicts an IP 54 protection class. The device can be mounted both horizontally and vertically. A diagonal orientation is not possible. When the unit is mounted in a vertical position, only the IM V3 position can be observed.

The minimum service life of the ball bearings of the SD motor is 20,000 hours. The device has a vibration quality level of N in accordance with DIN ISO 2373 specifications. The power supply to the product should be disconnected before performing any installation or connection work. Due to the excitation of the permanent magnets, the tacho and motor terminals tend to be live when the rotor is driven. The rated current of the unit in standstill mode is 35.0 A. The peak current of the device is 122.5 A. The motor has a winding resistance of 0.15 Ohm.

The SD motor has high resistance against demagnetization. Its admissible peak torque seems to be three times its rated torque. The device features a large overload capacity via advantageous heat dissipation. The product is safeguarded against thermal overload by means of the NTC thermistor present in its windings. The device is associated with a standard design and has no customization.
