Product Description

The Bosch Rexroth SD-B5.250.020-01.000 permanent-field servomotor is designed to be used with a compatible inverter from the same manufacturer. The unit has permanent magnets in its rotor. The device has an IP 54 protection class as per DIN 040 050 / 40 053 specifications. The motor is not equipped with a built-in encoder because it cannot be customized. The product has ball bearings at its driving end or flange end. The user should never knock or hammer the shaft extension as this can damage the rotor and the ball bearings.

Before operating the SD motor for the first time, the user should check the motor-module combination with the help of the type label. If an unapproved module is connected, it is likely to restrict the operation of the device and may also damage it. Mating connectors do not come with the product package. If required, they should be ordered separately. A fixed bearing can be found at the driving end of the device. For monitoring the temperature, the motor uses an NTC thermostat that is integrated into its windings.

The SD motor should be connected only using the cables supplied by the manufacturer. The basic construction style of the device is IM B5 according to DIN IEC 34-7 specifications. The product features a standard design and customization is not possible. The product should not be dismantled by the user. Its tacho board can be removed in the case of replacement. The protection rating of the motor’s braking resistors is IP 20. The unit exhibits reduced output if its ambient operating temperature is exceeded. At least one supply module is required for the product to function.
