Product Description:

The SG-B0.014.058-03.015 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. The unit is intended for closed-loop motion axes in packaging machines, pick-and-place gantries, and similar automated equipment where compact rotary power is needed. By converting command currents from the drive into mechanical torque, it provides fast positioning for repetitive machine cycles. Its integrated resolver supplies rotor-angle feedback to the controller for accurate speed and position regulation under changing loads.

At standstill, the motor can continuously maintain a torque of 1.70 Nm while the windings draw 4.0 A of current. The torque calculation factor of 0.43 Nm/A relates winding current to the torque produced by the motor. The motor reaches a nominal speed of 6200 rpm, making it suitable for direct coupling to high-speed spindles or belt-reduction stages. A flange diameter of 55 mm supports installation with the IM B5 face-mount pattern and helps align the motor with the connected machine. The shaft mates with compatible hubs, while a PTFE shaft seal protects the drive-end bearing area. The drive end has IP65 protection against dust and low-pressure water jets, helping prevent contaminants from reaching the bearings and resolver compartment.

During power-off conditions, the attached spring-applied brake provides 0.9 Nm of static holding torque to prevent unwanted shaft movement. The brake is electrically released by a 24 V ±10% supply, allowing the drive system to disengage it before motion begins. Its coil consumes 11 W, limiting the additional heat generated near the motor housing. Torque is transferred through a parallel key with a feather-key size of 3 × 3 × 14 mm, which provides positive engagement with a compatible coupling or hub during acceleration. The resolver reports the rotor angle to the controller without relying on mechanical contacts that could wear during repeated operation. The face-mount arrangement keeps the shaft center aligned with compatible gearboxes and driven components, reducing coupling stress when the motor is installed correctly.
