Product Description:

The MHD041B-144-NP1-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Classified as a servo motor, it converts drive current into regulated rotary motion for industrial axes and uses relative position detection so the controller can command repeatable moves without secondary sensors. This motor is supplied with a keyed shaft so torque can be transmitted directly to couplings, and its feedback channel relies on an optical measurement method for high-resolution position data.

A continuous stall capability of 2.7 Nm is the base torque the axis can hold under closed-loop control. The enclosure carries a protection rating of IP65, which seals the internal windings against dust and low-pressure water jets. Heat generated by the stator is removed through liquid cooling, and the coolant jacket is integrated into an 82 mm square flange, so the mounting interface measures 82 mm on each side. Rotor angle is reported through digital servo feedback (HSF), which supports high-speed data exchange with Indramat drive modules. The motor uses a 50 mm pilot diameter to align with machine plates that match the 041 frame size. A turnable power connector, adjustable through 270°, and a combined feedback plug simplify cable routing, while the shaft seal helps keep coolant or lubricants out of the bearing cavity.

An integrated holding brake delivers 2.2 Nm of static torque to keep the load secure whenever the servo is de-energized. During operation, positional repeatability remains within ± 0.5 angular minutes at ambient temperatures from 0 to 40 °C, allowing precise indexing across the permitted operating range. The F-class insulation tolerates winding temperatures associated with dynamic duty cycles, and storage is permitted from -20 to 80 °C. Operation is allowed up to 1000 m above mean sea level. The B-length body with winding code 144 balances compact size with the intended inertia range.
