Product Description:

The SG-B0.014.058-00.000 is a brushless servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Built for closed-loop positioning in industrial automation, it converts three-phase current from a drive controller into controlled rotary motion for pick-and-place heads, miniature gantries, and spindle-orienting stations. Its metallic housing supports IM B5 flange mounting, and IM V1 or IM V3 mounting orientations are also permitted. A shaft with a keyway couples directly to gears or pulleys for positive torque transfer. An internal resolver reports the rotor angle to the drive, allowing the control system to correct position and speed during operation.

At a nominal speed of 6200 rpm, the motor accommodates fast operating cycles while retaining closed-loop position control. A static torque of 1.70 Nm is available for holding a continuous load at zero speed, and the drive must supply a standstill current of 4.0 A to produce that torque. The shaft measures 9 mm × 20 mm and follows DIN 6885, allowing compatible couplings to seat correctly on the keyway. A flange size of 55 mm keeps the mounting footprint compact for use in densely arranged multi-axis equipment. The combination of a keyed output shaft and resolver feedback supports synchronized movement when the motor operates as part of a coordinated machine axis.

The enclosure meets IP65, preventing dust ingress and resisting low-pressure water jets near coolants or lubricants. The windings use Class F insulation, which permits an internal insulation temperature of up to 155 °C before thermal derating is required. High-energy SmCo magnets maintain torque production across a broad temperature range and resist demagnetization during temporary overload conditions. Operation is permitted at ambient temperatures from 0 to 40 °C, and heat is removed through natural convection and radiation without forced-air or liquid cooling. The passive cooling method avoids the need for fan power, external coolant lines, and additional moving components around the motor housing.
