Product Description:

The SG-B1.016.060-03.000 is a brushless servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It converts electrical energy into precise rotary motion for positioning tables, feed axes, and spindle drives, giving machine builders a compact source of controlled speed and holding torque in automated equipment. Heat generated by copper losses is dissipated through thermal radiation and natural convection, eliminating the need for forced-air or liquid cooling.

During continuous operation, the motor reaches a nominal speed of 6300 rpm, so drive controllers can command high tool surface velocities without gear reduction. Its static torque of 1.65 Nm indicates the load it can hold at standstill, while a standstill phase current of 4.5 A must be supplied by the drive electronics to achieve that torque without motion. The integrated holding brake engages at 24 V DC ±10%, allowing vertical or indexing axes to remain locked when power is removed. A resolver embedded in the stator reports rotor angle and shaft speed for closed-loop control. The sealed housing meets IP65, so airborne dust and directed water jets do not reach the internal windings.

The rotor employs SmCo permanent magnets, providing high coercivity and thermal stability during repetitive acceleration cycles. A mounting flange measuring 70 mm across with accuracy N aligns the stator concentrically with adjoining machine frames. The housing follows the IM B5 face-mount layout and supports optional IM V1 or IM V3 vertical orientations. Shaft output is delivered through an 11 mm × 23 mm keyed journal made according to DIN 6885, ensuring positive torque transmission to pulleys or couplings. Internal windings meet Insulation Class F, allowing conductor temperatures up to 155 °C when the ambient temperature remains within 0 to 40 °C. The metallic housing resists vibration, and a 1.5 mm² mating connector simplifies wiring while maintaining a compact cable size.
