Product Description:

The SD-B3.031.030-10.000 is a brushless servo motor assembled by Bosch Rexroth Indramat in the SD Magnet Motors series. It is intended for closed-loop motion control and converts electrical input from a matched drive into regulated mechanical power for positioning tables, feeders, and light handling axes on automated lines. Permanent magnets on the rotor and electronic commutation eliminate brush wear, while the motor maintains steady velocity and torque during continuous-duty operation. This arrangement supports repeatable axis response in packaging, assembly, and transfer equipment that depends on smooth servo regulation.

The motor mounts through a standard square flange measuring 116 mm, which suits machine interfaces that use this bolt pattern. At nominal electrical excitation, it reaches a synchronous speed of 3000 rpm, a value commonly used in packaging and assembly stations. When held at zero speed, it delivers a continuous stall torque of 3.1 Nm, allowing the axis to support moderate static loads without overheating. Torque is transmitted through a cylindrical shaft ground to ø 19 × 40 mm, which works well with couplings or pulleys. Rotor excitation is provided by Ferrite magnets, which supply stable magnetic flux during normal operation.

The mechanical arrangement is standard basic equipment, and the shaft is supplied without a keyway so clamp-style hubs can be used. The motor is also delivered without a brake, so stopping and holding functions must be handled by the drive or by external mechanical hardware. These choices reduce rotating inertia and suit horizontal axes where a separate holding device is not required. The motor also uses the standard winding codes, connector styles, and thermal sensor arrangement associated with this product line, which helps maintain compatibility with matched drive systems.
