Product Description

The Bosch Rexroth SD-B5.250.020-11.000 permanent-field servomotor has a high surface temperature when it is in use. The user should not install the motor with its shaft facing downward. The device should always be connected to a compatible inverter; otherwise, it will have restricted operation. The unit uses different sockets for the power and tacho connections. The product has an N vibration quality level. Adequate heat dissipation should be ensured when installing the motor. There are two cooling methods: thermal radiation and natural convection. The device is a great choice for applications with stringent needs. The product performs electronic commutation. The motor is not equipped with a disk brake.

The SD motor features a temperature monitoring function. The shaft of the device does not have a keyway or a featherkey. The motor has a protection class of IP 54. The device supports two different types of connectors. The product should not be operated above the maximum ambient temperature range of 40°C. The unit must be operated only after reading the product documentation carefully. Only fully trained personnel should handle the installation, operation, and maintenance of the motor. The device does not come with a built-in encoder. The motor is designed to offer maintenance-free operation.

The permanent magnets in the SD motor are made of ferrite material. The device can be mounted in a vertical or horizontal orientation. It cannot be mounted in a diagonal position. If it is to be mounted vertically, it can be done so only in the IM V3 position. The tacho and commutation sensors portray a brushless version and are integrated into the motor’s non-driving end. The phase currents in the inverter are controlled by the commutation sensor.
