Product Description

The Bosch Rexroth SD-B5.250.015-41.000 is a best-in-class permanent-field servomotor in the SD series. The motor can deliver maintenance-free operation due to its brushless tacho. The unit’s housing surface must not be touched when it is live as it turns hot and can cause burns upon touching. The braking resistors of the device have a protection rating of IP 20. The product is well-suited for stringent requirements due to the design of its shaft. Before making any connection to the device, the power supply must be disconnected.

The SD motor tends to support straight and right-angled connectors. The device cannot be mounted in the IM V1 mounting style because it does not have an oil-tight bearing at its driving end. The unit often results in reduced output if the ambient operating temperature is exceeded. The NTC thermistor protects the product against thermal overload. The type label of the unit features technical details like standstill torque, standstill current, rotor inertia, and protection class. The connection between the inverter and the motor is done on the motor side via plug-in connectors.

The ball bearings of the device have a minimum service life of 20,000 hours. The two ways the unit is cooled are through thermal radiation and natural convection. The tacho and commutation sensors are located at the non-driving end. Radial and axial forces act on the shaft when the motor is in use. The driving end of the product is the end where its flange is located. The unit’s basic construction style is IM B5 in accordance with DIN IEC 34-7 specifications. The shaft of the motor is not equipped with a keyway or featherkey.
