Product Description:

The SG-B0.014.058-03.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. Designed for precision industrial automation, the unit converts controlled current from a compatible drive into rapid, repeatable shaft rotation for pick-and-place modules, feed axes, and small spindle applications. Its resolver supplies rotor orientation data to the drive controller, enabling closed-loop position and speed regulation. A compact electromagnetic holding brake prevents unintended shaft movement during standstill or power loss, which is especially useful for vertically mounted or intermittently cycled equipment.

The motor has a nominal speed of 6200 rpm, supporting high throughput with lightweight tooling while remaining within its intended operating range. At standstill, it produces a static torque of 1.70 Nm with a continuous phase current of 4.0 A. Machine mounting follows an IM B5 pattern, and the front flange has a diameter of 55 mm, allowing direct attachment to compact gearheads or machine frames. The housing has an IP65 protection rating, which prevents dust ingress and resists low-pressure water jets. The integrated holding brake operates from a 24 V DC supply with a tolerance of ±10%.

The rotor uses SmCo samarium-cobalt magnets to maintain stable air-gap flux across temperature changes, supporting consistent torque during thermal cycling. The permitted ambient temperature range is 0 to 40 °C, and heat is removed through thermal radiation and natural convection. The windings use Class F insulation, which supports internal hot-spot temperatures up to 155 °C and provides thermal capacity for short-term overloads during rapid indexing. A keyed shaft with a diameter of 9 mm transfers torque to compatible couplings while preventing rotational slip under load.
