Product Description:

Bosch Rexroth Indramat manufactures the MHP115C-058-HP0-ANNNNN as part of the MHP Synchronous Motors series. The motor serves as a torque-dense rotary actuator for servo drives in industrial automation, where its permanent-magnet design supports accurate velocity and position regulation under CNC or PLC control. It integrates with Rexroth digital drives to form closed-loop axes that move tooling carriages, gantries, and transfer stations with repeatable response. By combining electronic feedback with brushless construction, it delivers low-maintenance operation across extended duty cycles.

With a continuous standstill torque of 70.0 Nm, the unit can hold substantial static loads while the natural-convection housing removes heat without forced airflow. The sealed stator enclosure meets IP65, blocking dust ingress and water jets so the motor can be mounted outside control cabinets. Position information comes from an incremental encoder delivering 2048 increments per revolution, enabling tight servo loops for contouring or rapid index moves. A keyed shaft with sealing ring transmits torque to couplings or gears while preventing lubricant escape along the journal. The electrical and mechanical ratings are valid in ambient conditions from 0 to +40 °C, ensuring performance stability on factory floors and automated assembly lines.

Thermal endurance is reinforced by windings built to class F insulation limits, allowing high internal temperatures without loss of dielectric strength. The mechanical footprint follows frame size 115 with length code C, giving a balanced ratio of torque to inertia for mid-frame servomotor applications. Drive compatibility stems from winding code 058, which matches the nominal voltage constant and current used by compatible Rexroth power modules. Because the rotor assembly is supplied without a holding brake, vertical axes must secure loads through external clamps or regenerative torque from the drive.
