Product Description:

Bosch Rexroth Indramat manufactures the MHD112C-024-PG0-RN, a servo motor in the MHD Synchronous Motors series. The unit serves as a rotary actuator that converts commanded current from a drive controller into precise torque for positioning axes inside packaging machines, machining centers, and material-handling cells. It is intended for closed-loop motion tasks where rapid acceleration, repeatable speed, and accurate holding of programmed positions are required in industrial automation. In servo applications, the motor works with the controller to correct for changing load conditions so commanded speed and position remain stable during indexing and transfer moves.

At standstill the motor delivers 38.0 Nm of continuous torque, providing steady holding force without overheating. Mechanical mounting is centered by a 130 mm pilot diameter, and the square flange is 192 mm wide to distribute load across the gearbox. Internal passages circulate coolant through the stator, so the housing uses liquid cooling to remove losses and permit higher power density than air-cooled designs. The motor uses size 112 and length C for its active iron stack, while winding code 024 sets the coil pattern for the corresponding voltage constant and rated current. The power cable exits to the right of the endbell, which can help keep cable bends clear of adjacent machine structure in compact layouts.

The drive end uses a plain shaft without keying so clamp couplings fit with minimal concentricity error, and a shaft seal helps block coolant splash. Position is measured by a digital servo feedback encoder that supplies absolute (>4096 revolutions) data to the controller, allowing the axis to retain position information across extended travel. Power is delivered through a power connector, and the assembly is supplied without a holding brake, suiting installations that rely on external clamps or motor torque for static security.
