Product Description:

The SG-B1.034.036-14.010 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It is intended for closed-loop position and velocity tasks in automated machinery, where the drive controller regulates stator current to match commanded motion profiles. By converting electrical energy into controlled rotary torque, this motor allows indexing tables, pick-and-place axes, and light machining spindles to follow precise trajectories with stable speed control. It is well suited for machines that need repeatable acceleration, steady running speed, and accurate stopping at commanded positions.

During continuous operation the rotor can turn at a nominal speed of 3900 rpm, giving high linear feed rates when coupled to belts or ball screws. Holding the shaft motionless, it can maintain a standstill torque of 3.70 Nm, which is developed with a standstill current of 5.9 A. This current level must be supported by the matched drive amplifier during zero-speed holding. The magnetic design yields a torque constant of 0.66 Nm/A, so commanded phase current translates predictably into motor torque. An enclosure protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, enabling cabinet-free mounting on machine frames exposed to coolant or airborne particulates.

The square mounting interface follows a flange dimension of 70 mm, allowing the motor to bolt directly to compact gearheads or adapter plates without extra spacers. Power is transmitted through a shaft that measures Ø11 mm × 23 mm. This shaft geometry is suited for keyed or clamp couplings in low-to-medium torque ranges. The compact mounting face and short shaft proportions help the motor fit tightly spaced axis layouts where direct connection to the driven mechanism is preferred. That arrangement is useful where nearby guarding, slides, or transfer tooling leave limited room for oversized couplings or spacer blocks.
