Product Description:

The MHP112C-035-HG0-BNNNNN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat for the MHP Synchronous Motors series. It acts as the rotary element in closed-loop drive systems, supplying regulated torque and speed to machine axes in packaging, handling, and machining cells. In this role, the motor converts drive commands into controlled shaft rotation for indexing, acceleration, and steady-speed operation. A natural-convection housing and a sealed shaft allow installation inside protective enclosures where forced cooling is not required, while the standardized frame dimensions support integration into established machine layouts.

Under natural convection, the motor develops a continuous standstill torque of 38.0 to 43.5 Nm, providing steady force for positioning tasks even when the rotor is locked. The drive shaft is a plain shaft with a sealing ring, so lubricant remains inside the gearbox and contaminants stay out. A cast housing rated to IP65 blocks dust ingress and water jets, enabling direct mounting on moving axes without additional covers. Rotor position is reported through an incremental encoder with 2048 increments, giving the controller fine resolution for velocity loops and stable position feedback during repeated motion. Electromechanical behavior uses winding code 035, which matches the motor to compatible power modules and corresponds to its nominal current range.

Thermal limits are respected when the ambient remains between 0 to +40 °C, and heat leaves the frame by natural convection so no external fan wiring is required. The unit is supplied without a holding brake, which reduces mass and inertia where mechanical clamping or static torque from the drive can secure the load. Coil insulation conforms to insulation class F, allowing winding temperatures up to 155 °C during peak duty cycles without degradation. The mechanical envelope follows motor size 112, and cabling exits toward side B of the stator, which helps when machine layouts require rear-facing connectors and clear routing around nearby components.
