Product Description:

The MHD112C-058 is a servo motor built by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As an electrically commutated unit, it converts drive current into controlled rotary motion, allowing CNC axes, packaging machines, and material-handling stations to track commanded positions and velocities with high repeatability. This operating principle supports precise acceleration, stable speed control, and accurate position holding when the motor is matched with a compatible drive. It is intended for motion applications that depend on coordinated torque production rather than fixed-speed operation.

Its continuous stall torque of 38.0 Nm is the steady load the rotor can hold without thermal rise beyond rated limits, giving a baseline for static axis requirements. The motor seats against positioning fixtures through a centering pilot of 130 mm, which keeps shaft alignment concentric to connected gearboxes or pulleys. A square attachment face with a 192 mm flange dimension provides the bolt pattern common to IEC-compatible machinery. Mechanical depth is indicated by the length code C, which marks the third frame depth in the MHD family and affects overall inertia. The frame size index 112 identifies the stator outside diameter, so mounting hardware must match this motor size. This frame geometry also affects the space required behind the mounting surface.

These mechanical values are combined with winding code 058, which sets phase resistance and inductance so the motor can pair with converters that supply the necessary current bandwidth. The unit follows the common thermal sensing and feedback connection approach used across the MHD Synchronous Motors range, which helps maintain compatibility with matching drive systems. The selected winding also influences how the motor responds to drive current commands during acceleration and deceleration. In automated lines, that helps the axis maintain smooth motion while following frequent speed changes and position updates. The motor can be used in direct-drive layouts or in geared assemblies where steady torque delivery is important to the motion profile.
