Product Description:
The MHP041B-144-HG1-UNNNNN is a permanent-magnet servo motor manufactured by Bosch Rexroth Indramat for the MHP Synchronous Motors series. It functions as the rotary actuator in CNC positioning stages, pick-and-place modules, and other motion axes where closed-loop velocity and position regulation are required. The model connects directly to an intelligent drive controller that meters current to deliver commanded speed or torque profiles in industrial automation cells. Because current is regulated by the paired drive, the motor can be used for coordinated indexing, contouring, and repeatable point-to-point motion in automated equipment.
The motor has a frame size of Motor Size 41 and a motor length of Motor Length B. It provides a continuous standstill torque of 2.7 Nm under natural convection, which suits compact axes that must hold load without forced cooling. The winding is identified as Winding Code 144, and the stator uses Insulation class F for thermal durability during sustained operation. The housing is rated IP65, which helps protect internal parts from dust and low-pressure water when the shaft seal is installed correctly. Its compact housing can fit machine layouts where installation space is limited, while the sealed enclosure supports use near areas that are cleaned periodically.
The permitted ambient operating range is 0 to +40 °C, so the motor is intended for standard industrial indoor conditions. A permanent-magnet holding brake supplies 2.2 Nm of static braking torque when power is removed, which helps keep vertical or suspended loads from drifting at standstill. Position data reach the controller through an incremental encoder, 2048 increments, allowing speed feedback and homing reference detection. This feedback arrangement lets the drive monitor rotor movement continuously and correct deviation quickly during acceleration, deceleration, and low-speed positioning tasks. The motor uses a plain shaft with a sealing ring, and the power connector can be rotated 270° to ease cable routing in tight spaces.
