Product Description

The SD-B5.380.020-00.000 is a reliable permanent-field servomotor from the house of Bosch Rexroth. The driving-end shaft extension of the motor is equipped with a featherkey and keyway as per DIN 6885 for keyed torque transmission. The motor cannot be used alone. It should always be operated with a compatible inverter from the same manufacturer. The unit sports a brushless tacho. The temperature monitoring of the device is evaluated in the inverter. The device has an IP 54 protection standard. There are separate sockets for the tacho, power, and brake connections.

The connectors of the SD motor are fitted with plastic protective caps. These caps should remain on the servomotor and should be screwed on if the device is returned to avoid damage to the sockets during transport. The rated current of the device in standstill mode is 23.7 A. The unit’s peak current at 20°C is 71.1 A. The torque constant of the motor is 1.60 Nm/A. The mechanical time constant of the product at 20°C is 6.5 ms. The motor is 590 mm long and weighs 80 kg. The device has a large overload capacity by means of advantageous heat dissipation.

The SD motor has a NTC thermostat integrated into its windings for monitoring the temperature. The unit’s terminal block is located in its upper right corner. The user should use only the cables supplied by the manufacturer to connect the motor. To connect the motor to the inverter, there are plug-in connectors. The flange of the device is located at its driving end. The product’s basic construction style is IM B5 in accordance with DIN IEC 34-7 specifications.
