Product Description:

The SG-B1.034.036-00.017 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. It is intended for closed-loop motion axes in packaging, assembly, and handling equipment. Its compact format and resolver feedback make it suitable for positioning tasks that need accurate rotary control without a large motor envelope.

This model reaches a nominal speed of 3900 rpm, allowing fast cycle times when paired with a matched drive. At standstill, it can deliver 3.70 Nm of continuous holding torque while drawing a standstill current of 5.9 A. The NTC thermistor mounted in the stator tracks winding temperature to keep current within safe thermal limits during operation. The torque constant is 0.66 Nm/A, so the drive can relate commanded current to expected output torque. Overall electrical demand is 1.3 kVA, which suits mid-range servo amplifiers. Rotor position is supplied to the controller by a 2-pole brushless resolver, giving rotor angle information without the need for batteries. A maximum axial load of 75 N may be applied to the shaft during assembly, and the resolver and power windings are sealed against dust and low-pressure water.

The square mounting face follows the ISO flange code of 70 mm, and the housing length without a holding brake is 204 mm to keep the envelope compact. Dynamic response benefits from a rotor inertia of 0.097 × 10⁻³ kg·m², which helps limit overshoot in start-stop profiles. The enclosure is sealed to IP65, so gasketed connectors can be used where dust and water spray are present. Weight without a brake is 3.5 kg, which helps reduce handling effort during installation. Transmission components attach to the Ø11 × 23 mm shaft through a keyway and feather key, using the supplied 4 × 4 × 16 mm key. The motor end bell supports the shaft against radial forces generated by couplings, and the keyed output supports secure torque transfer to connected components.
