Product Description:

The MHP112B-058-HG0-BNNNNN is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MHP Synchronous Motors series. This motor converts electrical drive commands into controlled torque and speed for industrial automation axes that need repeatable positioning, such as pick-and-place modules and forming presses. Its 112 frame size and B-length stator provide a useful balance of power density and installation space for common machine layouts.

During continuous stall operation, the motor delivers 28.0 to 31.0 Nm of torque while relying on natural convection to move heat to the surrounding air. The winding and bearing set remain within operating limits when the ambient air stays between 0 to +40 °C, and the housing has an IP65 rating that helps block dust and low-pressure water jets. Position feedback is supplied by an incremental encoder with 2048 increments, providing fine resolution for digital drive controllers that manage precise velocity and position loops. Power enters on side B through a keyed connector, which helps keep cable routing orderly when several axes are installed in the same machine section.

The motor has a plain shaft with a sealing ring, which supports rigid couplings while helping keep contaminants away from internal components. It is supplied without a holding brake, so load holding during power loss must be handled by the machine design or the connected drive system. The windings use Class F insulation, allowing higher internal thermal tolerance than lower insulation classes. Electrical behavior follows winding code 058, which gives the motor the resistance and inductance characteristics expected by compatible drive units. The connector is oriented toward the non-drive end, supporting installations that need straightforward access to the power connection.
