Internal Product Review
The SG-B3.150.024-10.010 is a brushless servo motor with IP65 protection and cooling by thermal radiation and natural convection. Resolver feedback for rotor orientation and spindle speed supports accurate regulation, while 16.6 Nm static torque gives the motor strong standstill performance. A nominal speed of 2700 rpm makes this SG synchronous servo motor a very capable choice for precise industrial servo applications.

Product Description:
The SG-B3.150.024-10.010 is a brushless servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It converts drive-module power into controlled rotary motion for positioning tables, feed axes, and pick-and-place heads used in automated manufacturing. A metallic housing provides structural strength, while the smooth shaft allows direct coupling to machine components so the motor can deliver precise motion without added transmission backlash.
The motor develops a nominal speed of 2700 rpm, giving machinery a moderate top velocity while maintaining high feedback resolution. Its static torque rating of 16.6 Nm indicates the load it can hold at zero speed, and the drive must supply a standstill current of 18.2 A when that torque is required. The mounting interface has a flange size of 140 mm and an accuracy grade of R. The housing has an IP65 protection rating, which seals internal components against dust and water jets. The standard mounting orientation is IM B5, while IM V1 or IM V3 may be used for vertical installation. A resolver fitted to the rotor supplies position data to the control loop.
Ambient operating temperatures are limited to 0 to 40 °C, and the windings use Class F insulation, which permits winding temperatures up to 155 °C without deterioration. Heat generated during operation is removed through thermal radiation and natural convection, eliminating the need for forced-air or liquid cooling. High-energy magnets made from SmCo provide magnetic flux that remains stable during temperature changes, supporting consistent servo stiffness. The shaft has a diameter of 24 mm and a length of 50 mm, allowing it to fit compatible couplings with the required bore depth. The motor is delivered without a holding brake, so an external locking device is required if the load must remain fixed when power is off.
