Product Description:

The SD-B5.250.020-01.000 is a brushless servo motor built by Bosch Rexroth Indramat for the SD Magnet Motors series. In automated machinery, this unit converts controlled current from a drive amplifier into precise mechanical rotation, allowing axes to accelerate, decelerate, and hold position as commanded by a motion controller. Its electromagnetic circuit is arranged for direct mounting on factory equipment where repeatable positioning and continuous duty operation are required. This layout suits motion systems that need accurate shaft response during frequent starts, stops, and direction changes.

The motor attaches to gearboxes or load flanges with a face measuring 116 mm, so the mounting pattern matches standard IEC frameworks used in conveyors and packaging stations. Rotor excitation relies on Ferrite permanent magnets, providing stable flux density without rare-earth materials. A rated speed of 2000 rpm marks the synchronous operating point used for continuous operation. When the shaft is locked but energized, the motor can sustain 25 Nm of torque, which is useful on axes that must resist a static load without movement. Mechanical connection to couplings or pulleys is through a shaft sized ø 19×40 mm, giving adequate key length for secure torque transfer under dynamic loads.

This motor uses electronic commutation, so maintenance associated with brush wear is eliminated and torque production remains smooth across the normal speed range. It is supplied in a standard electrical and mechanical configuration without factory customization. The feedback and thermal sensor wiring support connection to compatible drive controllers in multi-axis systems. That arrangement helps integrate the motor into established servo installations where consistent signal handling and temperature monitoring are required for stable operation.
