Product Description:

The MHD041B-144-NG1-UN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as an electromechanical actuator that delivers position-controlled rotation for packaging, assembly, and pick-and-place machinery. By combining electronic commutation with high-resolution internal feedback, the unit allows drive controllers to command speed or torque with minimal lag and maintain accurate motion profiles in multi-axis systems. Its synchronous design supports repeatable axis movement where fast response and stable regulation are required during frequent starts, stops, and directional changes.

Mechanically, the stator face attaches to machinery through an 82 mm square mounting flange, and the rotor seats on a centering collar measuring 50 mm in diameter. This arrangement helps keep radial runout low during repeated cycling and supports accurate alignment with couplings and driven assemblies. At standstill, the motor can deliver 2.7 Nm of continuous torque, which supports holding duty and low-speed indexing without thermal overload. Thermal energy leaves the windings through an integrated jacket that supports liquid cooling, so the motor can maintain output in enclosed installations. Position and velocity data are produced by the integrated Digital servo feedback (HSF) transducer, allowing rapid updates to the connected drive. The motor uses a plain shaft for coupling attachment, and a shaft seal limits the migration of lubricant and contaminants. Power and feedback connections are combined into one interface, which helps keep cable routing compact.

A factory-mounted holding brake supplies 2.2 Nm of static torque so suspended or vertical loads can remain secured when power is removed. The motor uses winding code 144 in the compact size 041 frame with motor length B, matching the current rating of the associated drive. The power connector can be rotated within 270°, allowing the cable exit direction to be adjusted for the available installation space. Relative position acquisition is used, so the controller must perform a homing cycle after power-up to establish an absolute reference.
