Product Description:

The MHD115A-035-NG0-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Serving as a rotary actuator in industrial automation, it provides closed-loop motion control for indexing tables, gantries, and conveyor axes. The motor has a 115 frame designation and A length, which balance installation space with usable torque for moderate-power drive systems.

The unit delivers a continuous standstill torque of 32.0 Nm, allowing it to hold or move loads steadily while remaining within thermal limits. A housing rating of IP65 protects the windings and bearings from dust ingress and low-pressure water jets, making the motor suitable for enclosed washdown areas. Rotor position is reported through Digital servo feedback (HSF), which provides high-resolution incremental data to the drive for precise velocity and position control. The mounting interface uses a 192 mm square flange pattern for compatibility with standard machine mounting surfaces. Additional features include insulation class F, a plain shaft for backlash-free coupling, power cables exiting toward side B through an output connector, and relative position detection for the drive’s multi-turn reference routine.

Thermal management relies on natural convection, so no external blower or liquid circuit is required. Tracking accuracy of ± 0.5 angular minutes supports fine positioning of lightweight tooling. A centering diameter of 180 mm helps maintain concentric alignment with adjoining machine frames. The motor operates in environments from 0 to 40 °C and can be installed up to 1000 m above mean sea level without derating. It is supplied without a holding brake, so shaft locking during power-off must be provided by the mechanism or by static drive torque, and a shaft seal is present to limit lubricant migration.
