Product Description:

The MHD112B-024-PG0-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It couples digital drive electronics to a permanent-magnet rotor so that commanded currents produce proportional shaft torque and speed. In multi-axis machining centers and material-handling cells, the motor works as a tightly synchronized actuator that positions loads with high repeatability. This operating role makes it suitable for axes that require responsive motion, controlled acceleration, and stable feedback during repeated production cycles.

At standstill, the motor can deliver a continuous torque of 28.0 Nm, and that output is supported by liquid cooling through the stator jacket. Mechanical alignment is simplified by a 130 mm centering diameter, and ingress protection is rated at IP65 so dust and water jets cannot reach live parts. Position feedback is provided by a digital servo encoder with optical scanning, giving a system accuracy of ± 0.5 angular minutes and supporting precise closed-loop motion. The shaft is plain and sealed, which helps protect the bearing area during operation. The motor uses size code 112 with length code B, while winding code 024 and an output connector on side A establish its electrical connection to the drive.

Thermal endurance is backed by Class F insulation, allowing winding temperatures up to 155 °C, while safe operation is maintained between 0 to 40 °C ambient. For storage or transport, the unit tolerates −20 to +80 °C, and installation is permitted up to 1000 m above mean sea level without derating. The mounting flange spans 192 mm, giving a broad contact area for secure attachment to the machine structure. Because the motor does not include a holding brake, static load retention must be provided externally when the axis is stopped. These operating limits support use in enclosed machinery where motion accuracy and dependable thermal performance are both required.
