Product Description:
The MHP112C-058-HP0-ANNNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MHP Synchronous Motors series. It serves as the rotary actuator in positioning and velocity-regulated axes that depend on high torque at low speed and precise feedback for closed-loop motion control in automated machinery and material-handling cells. Its synchronous design supports stable torque production during indexing, feed, and transfer applications where repeatable motion is required over long duty cycles. Because the motor is supplied without an integrated holding brake, static load retention must be provided by the drive or by an external brake when the axis is stopped.
This motor can generate a continuous standstill torque between 38.0 to 43.5 Nm, enabling it to hold loads without overheating when airflow is limited. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, so cabinet placement is optional. Operation is specified for ambient temperatures from 0 to +40 °C, matching typical industrial climates without derating. Rotor position is monitored through an incremental encoder with 2048 increments, allowing the drive to resolve small angular changes for tight speed regulation. This feedback arrangement helps the control loop maintain smooth rotation during indexing, creeping motion, and repeated position correction. The windings are insulated to F class limits, permitting higher internal temperatures before insulation breakdown and providing additional thermal headroom during cyclic duty.
A keyed shaft with a sealing ring transmits torque while helping block lubricant migration. The keyed output is suitable for common hubs, pulleys, and couplings that need positive torque transfer without shaft slip. Cooling is done by natural convection, which eliminates forced-air components. Winding code 058 corresponds to the electrical parameters used by compatible Rexroth power modules. Power and feedback conductors exit through a connector on side A, so harness routing remains predictable when the motor is installed in tight frames. The 112 frame size and C-length provide a balanced envelope for high torque density without exceeding the stated ambient temperature range.
