Product Description:

The SD-B6.480.020-00.000 is a servo motor built by Bosch Rexroth Indramat and released under the SD Magnet Motors series. As a dedicated drive component, it converts electrical energy into controlled mechanical rotation that can be synchronized with motion controllers in packaging, handling, and positioning machinery. It delivers high torque from a compact footprint and serves as the actuator in closed-loop axes where velocity and angular accuracy are important. When paired with a suitable servo drive, it can support repeatable starts, stops, and speed changes during automated motion cycles.

At rest, the motor can hold a load with a torque of 48 Nm, which indicates its continuous stall capability. During operation, the rotor reaches a nominal speed of 2000 rpm, so the connected drive and gearing should be selected for that operating point. A flange interface of 142 mm allows direct mounting to gearboxes or machine frames while helping maintain alignment. Mechanical coupling is supported by a shaft ground to Ø 24 × 50 mm, which provides a consistent fit with standard clamping hubs. The rotor-stator system uses Ferrite magnets, providing stable magnetic flux without rare-earth materials. This motor layout is suitable for controlled rotary motion in equipment that requires dependable low-speed torque and steady running behavior.

The motor uses a shaft with keyway and featherkey, which helps secure transmitted torque during reversing loads. Because the unit is a brushless servo motor, commutation is handled by electronic commutation rather than brushes, so wear associated with brush contact is eliminated. The motor is intended for use in closed-loop axes, where the drive regulates speed and position through feedback signals. This arrangement supports consistent response during positioning and velocity-controlled motion, and it helps maintain stable operation across repeated machine cycles.
