Product Description:

The MHP112B-058-HP0-BNNNNN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MHP Synchronous Motors series. Designed as a drive element for positioning and velocity loops in industrial automation, it converts electrical energy from a matched inverter into controlled mechanical torque. This allows the motor to support axes that require repeatable motion under variable load. It is suitable for servo-driven machinery where stable torque delivery and accurate speed regulation are required across repeated operating cycles.

The motor delivers a continuous standstill torque of 28.0 to 31.0 Nm, allowing sustained force output while the stator temperature remains within insulation limits. Its enclosure is rated IP65, so dust ingress is prevented and water jets from any direction will not impair operation. The permitted ambient range is 0 to +40 °C, and operation beyond this range requires derating. Heat is removed solely through natural convection, eliminating the need for external fans and simplifying installation. Position and speed are resolved by an incremental encoder that outputs 2048 increments per revolution, providing fine feedback to the drive controller. The windings use insulation class F, which permits winding temperatures up to 155 °C before thermal aging accelerates.

A keyed shaft with a sealing ring transmits torque while the seal helps limit lubricant escape and protect the interior bearings from splash. This shaft arrangement also supports direct connection to common machine couplings. Power conductors exit through a connector on side B, which can simplify cable routing around nearby machine elements. The electromagnetic design uses winding code 058, which corresponds to electrical characteristics matched to compatible drive modules. Because the unit is supplied without a holding brake, any static load must be secured by external clamping or maintained drive torque during power-off conditions.
