Product Description:

The SG-B3.220.017-13.010 synchronous servo motor is produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. As a permanent-magnet AC unit, it converts drive current into precise shaft rotation for indexing tables, gantry axes, and light-duty machining heads. Integrated position feedback allows the connected controller to match programmed motion profiles with minimal following error. The motor’s sealed housing and compact footprint make it suitable for packaging lines, assembly robots, and other automated equipment that must fit within restrictive cabinet or arm envelopes while maintaining clean operation.

The mechanical interface uses a 140 mm square flange that mates directly with IEC gearboxes and IM B5 face mounts. Under dynamic duty, the rotor can accelerate to a maximum of 2400 rpm, while a permissible axial thrust of 200 N protects the bearings during thrust-loaded moves. At zero speed, the shaft can deliver 25 N·m of holding torque, and this static output is available when a phase current of 20.9 A is supplied by the drive. A rotor inertia of 1.84 × 10⁻³ kg·m² balances quick response with stable control, allowing rapid indexing without excessive overshoot. The motor has a minimum service life of 20,000 hours under the stated operating conditions.

During continuous operation, the motor runs at a nominal speed of 2200 rpm, yet it can absorb transients up to a peak current of 60 A for brief accelerations. The sealed housing has an ingress protection rating of IP65, so airborne dust and water jets do not compromise the internal windings. The stator assembly weighs 16.6 kg, measures 271 mm in length, and mounts in the IM B5 orientation with a keyed shaft measuring 24 mm in diameter and 50 mm in length. A torque calculation factor of 1.26 N·m/A links commanded current to expected electromagnetic output, supporting predictable drive control across the machine’s operating range.
