Product Description:

The SD-B4.140.030-01.000 is a servo motor produced by Bosch Rexroth Indramat and assigned to the SD Magnet Motors series. This unit is intended for closed-loop industrial automation where the drive must deliver repeatable angular positioning and velocity control. In a motion axis, the motor receives current from a matching amplifier and generates mechanical torque without brushes, which eliminates commutator wear and lowers maintenance demands. Its magnetic rotor and standardized mounting geometry allow integration into transfer lines, packaging machines, and light machining centers.

The motor uses a 142 mm square flange that aligns the housing to gearboxes or machine frames. Rotor excitation relies on Ferrite magnets, which provide stable flux density across a broad temperature range. The electrical design supports a nominal operating speed of 3000 rpm, allowing direct coupling to loads that benefit from a moderate base speed without additional reduction. As a Brushless servo motor, the stator windings are electronically commutated through Hall or encoder feedback, which supports rapid torque response. Power is transmitted through a shaft with a ground section measuring 24 x 50 mm, a size that fits standard clamping hubs and keyway bushings while keeping torsional deflection low.

At zero velocity, the motor can sustain 14.0 Nm of torque, which is suitable for holding vertical loads or overcoming static friction before acceleration begins. The motor is supplied in a standard configuration, so selection centers on the required drive setup and mechanical mounting. The build follows Bosch Rexroth Indramat production standards, so the insulation system, vibration resistance, and service markings match related motion products from the same brand. It belongs to the SD Magnet Motors series, and its encoder compatibility and inertia fit the operating range used across this motor platform.
