Product Description:

The MHP041B-144-HG0-UNNNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MHP Synchronous Motors series. It serves as a rotary actuator for closed-loop positioning and velocity tasks in automated machinery, delivering torque directly to the load through its plain output shaft. Use of this motor streamlines motion axes that rely on precise electrical commutation rather than mechanical gearing. This arrangement is well suited to compact equipment that requires accurate response during repeated speed changes and positioning moves.

At standstill, the motor can supply 2.7 Nm of continuous torque while cooled only by natural convection. This gives the motor usable stall capability without forced airflow. The housing is sealed to IP65, preventing dust ingress and protecting internal windings against low-pressure water jets. The windings use class F insulation so the conductors can withstand elevated operating temperatures within the insulation class limit. Position feedback is provided by an incremental encoder with 2048 increments, allowing the drive to maintain accurate speed and position control. Power enters through a connector that turns 270°, which helps with cable routing in confined spaces.

The motor operates in ambient temperatures from 0 to +40 °C, matching typical industrial enclosure conditions. Frame size 41 sets the mechanical interface dimensions used for this motor family. Internally, winding code 144 corresponds to the electrical resistance and inductance expected by matched servo drives. A plain shaft with a sealing ring supports coupling to adjacent mechanical components while helping protect the bearing area. The unit is supplied without a holding brake, so stationary load retention must be provided by external mechanics or by drive-applied torque. Motor length B keeps the housing compact while maintaining a practical balance between footprint and inertia.
