Product Description:

The MHD041B-144-PP0-UP is a servo motor produced by Bosch Rexroth Indramat as a member of the MHD Synchronous Motors series. The motor is intended for integration into industrial automation assemblies where rapid, precise rotary motion is required to position tooling, conveyors, or actuators under closed-loop drive control. Inside, a digital servo feedback encoder supplies real-time position data to the drive, and the encoder uses an optical measurement path. Its compact frame supports use in automated stations where installation space is limited.

The motor uses a flange size of 82 mm and a centering diameter of 50 mm, with a keyed shaft and a shaft seal that resist lubricant loss and airborne debris. Continuous stall torque reaches 2.7 Nm, providing steady holding force for indexing tables or small linear stages. The cast housing carries an IP65 rating and dissipates heat through natural convection, while the surface channels have IP68 protection. Power and feedback connectors can be rotated through 270°, which helps with cable routing when the motor is mounted in tight spaces. The motor uses winding code 144 with frame size 041 and length B construction, and it is delivered without a holding brake for applications that already include external locking hardware.

Permissible service temperatures range from 0 to 40 °C, while storage limits expand to -20 to +80 °C. The unit can operate at altitudes up to 1000 m above mean sea level without adjustment to its ratings. Positional accuracy is held to ±0.5 angular minutes, supported by Absolute (>4096 revolutions) detection within the encoder so multi-turn information is retained after power loss. Class F insulation withstands elevated copper temperatures. This motor is suitable for compact pick-and-place heads, print cylinders, and semiconductor handlers that require repeatable motion.
