Product Description:

The SG-B3.100.029-00.000 belongs to the SG Synchronous Servo Motors series manufactured by Bosch Rexroth Indramat. This brushless servo motor is intended for closed-loop positioning and speed regulation in industrial automation, where accurate torque delivery and rapid response support precise axis movement. A resolver monitors rotor orientation and returns position information to the connected drive, allowing the control system to regulate motor speed and commutation in real time. Its metallic housing supports installation in industrial processing areas where dust, moisture, and routine washdown may be present.

The motor reaches a nominal speed of 3500 rpm and supplies up to 11.2 Nm of static torque. Its standstill current is 15.6 A, indicating the current required to produce static torque while the shaft is stationary. The rotor uses SmCo permanent magnets, which resist demagnetization when the winding temperature rises during demanding operating cycles. The housing provides IP65 protection against dust and low-pressure water jets. Heat is dissipated through thermal radiation and natural convection, eliminating the need for forced-air cooling equipment. The flange uses the IM B5 basic design and permits IM V1 and IM V3 mounting orientations, allowing horizontal or vertical installation as required by the machine layout. The motor does not include a holding brake, so stationary loads must be secured by drive-applied torque or an external clamping mechanism.

The square 140 mm mounting interface provides a stable connection to a gearbox, machine plate, or other driven equipment. Power is transmitted through a shaft with a DIN 6885 keyway, providing positive engagement with keyed couplings and pulleys. The shaft has a 24 mm journal diameter and a keyed length of 50 mm, providing sufficient engagement along the coupling bore. The windings use Class F insulation according to VDE 0530, providing thermal tolerance during continuous operation. The permitted ambient temperature range of 0 to 40 °C supports operation in standard industrial environments without temperature derating. Grade N vibration severity limits transmitted vibration, while flange accuracy grade N supports consistent alignment with connected mechanical components.
