Product Description:

The SD-B5.250.015-01.000 is a permanent-magnet servo motor built by Bosch Rexroth Indramat for the SD Magnet Motors series. As a brushless unit, it converts drive current into rotation without commutator wear, making it suitable for closed-loop positioning tasks such as indexing tables, gantry axes, and packaging equipment. Its compact flange and medium-inertia rotor let the motor deliver regulated torque while fitting into machine layouts with limited mounting depth. When paired with a compatible servo drive, it supports controlled motion in applications that require steady speed response and accurate positioning.

The housing uses a 116 mm square flange that provides a standard interface for direct attachment to gearheads or mechanical frames. Inside the stator, the rotor uses Ferrite magnets, a material that provides stable magnetic flux and supports consistent torque production across the duty range. The motor reaches a nominal speed of 1500 rpm, which suits many general industrial motion tasks and moderate-speed axis designs. When the shaft is locked, it can deliver 25 Nm of continuous standstill torque, allowing actuators to hold position against static loads without an external brake. Power is transmitted through a 19×40 mm cylindrical shaft, giving enough contact area for keyless couplings while helping keep overhung load within bearing limits.

The motor is part of the SD Magnet Motors series, which uses a consistent mechanical format across the product line. Delivered as a brushless servo motor, the unit operates with electronic commutation from a compatible drive controller, eliminating brush maintenance and electrical arcing during operation. It is supplied with standard shaft sealing and standard insulation for general industrial use. This layout supports clean integration into servo systems where dependable torque delivery and compact installation are important.
