MHD115C-058-PG1-AN

The MHD115C-058-PG1-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. With a frame size coded as 115 and a length class C, this product type supports high continuous torque demands while keeping envelope dimensions compatible with mid-range machine frames. As a feedback-controlled rotary unit, it converts electrical commands from a drive into tightly regulated shaft motion, enabling repeatable positioning tasks inside automated assembly lines and gantry axes. Integration into closed-loop control networks is achieved through its built-in encoder, allowing the controller to monitor actual speed and position in real time.

At standstill the motor can generate 70.0 Nm of continuous torque, allowing heavy inertial loads to remain energized without thermal overload. Heat generated by the stator windings is carried away through Liquid cooling, so the rated torque can be delivered for extended cycles even when the motor is installed inside sealed machine frames. Position and velocity are measured by an integrated encoder that provides digital servo feedback, giving the drive controller high-resolution data for smooth commutation. Mechanical power exits the unit through a plain shaft, a design that eliminates keyways and reduces stress concentrations on the coupling hub. Electrical power enters through an output connector, which simplifies field replacement because no hard-wired terminals are opened during servicing.

The mechanical subsystem also contains a holding brake rated for 70.0 Nm holding brake torque, so vertical axes remain secure when power is shut off. Absolute position tracking over >4096 revolutions lets the machine recover its coordinates after an emergency stop without homing cycles. To protect the lubricant from contaminants, a shaft seal is fitted, and the power connector is oriented to side A, easing cable routing inside compact cabinets. Winding code 058 establishes the electrical resistance and inductance that the drive must match for proper current regulation.
