Product Description:

The MHP112D-027-HP3-ANNNNN is manufactured by Bosch Rexroth Indramat and belongs to the MHP Synchronous Motors series. The unit is a rotary drive element used with digital servo amplifiers to deliver controlled motion in automated assembly cells, conveyors, and machining centers. By providing high torque density and encoder-based feedback, the motor enables precise speed regulation and repeatable positioning under changing load conditions. This arrangement supports smooth acceleration and accurate stopping in servo-controlled machine axes.

The continuous torque rating under natural convection is 48.0 to 57.0 Nm, indicating the sustained mechanical load the rotor can support without active cooling. When stationary or during power loss, a holding brake supplies 70.0 Nm, allowing vertical axes to maintain position without external clamps. The drive shaft is supplied as a keyed shaft with a sealing ring, giving secure torque transmission while helping block lubricant escape toward the bearings. A housing sealed to IP65 prevents dust ingress and water jets from reaching internal windings, so the motor can be mounted directly on the machine frame. Position information comes from an incremental encoder with 2048 increments, which provides fine pulse resolution for the drive controller’s velocity and position loops.

The allowed ambient range of 0 to +40 °C matches standard control cabinet climates and avoids torque derating in typical plant environments. Windings built to insulation class F withstand internal temperatures up to 155 °C, supporting reliable operation during cyclic duty. The mechanical form factor uses motor size 112 and length class D, giving a stator stack that balances inertia with peak torque capability for mid-frame machinery. Electrical characteristics are tied to winding code 027, allowing compatible drive tuning and current limits. Power leads exit toward side A, which can simplify cable routing when the motor is mounted close to adjacent machine members.
