Product Description:

The MHP112D-027-HG0-BNNNNN is a servo unit produced by Bosch Rexroth Indramat within the MHP Synchronous Motors series. It drives rotary axes and spindles in automated machinery where precise speed regulation and repeatable positioning are required. By converting controlled phase current into mechanical rotation, this motor forms a direct electromechanical link between the drive controller and the moving load in industrial automation cells. In automated equipment, it is suited to motion tasks that require steady response during repeated starts, stops, and speed changes.

Under natural convection, the motor supplies a continuous standstill torque of 48.0 to 57.0 Nm; this value describes the load it can hold indefinitely without forced cooling. The frame size is 112, and the length code is D, so the stator stack has added magnetic volume without changing the mounting pitch. Electrical behavior follows winding code 027, which sets the phase resistance and inductance used with compatible Rexroth drives. Position feedback uses an incremental encoder delivering 2048 increments per revolution, giving the controller fine interpolation capability for smooth velocity control. The housing cools through ambient airflow, and the motor is supplied without a holding brake, so the load must be secured by external mechanics or drive torque when power is removed.

The enclosure carries an IP65 rating, which blocks dust ingress and resists low-pressure water jets. Class F insulation allows winding temperatures up to 155 °C during cyclic duty. A plain shaft with a sealing ring helps retain lubricant at the gearbox interface while limiting contaminant entry. This shaft arrangement is intended for coupled drive trains where sealing at the connection point helps keep contaminants away from internal components. Power cabling exits toward side B of the terminal area to simplify routing, and safe operation is specified for ambient conditions from 0 to +40 °C.
