Product Description:
The MHD112B-024-PG1-RN is a servo motor engineered by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It provides electrically commutated rotary motion for industrial automation axes that need stable torque, high positional fidelity, and direct feedback to a drive controller. The motor is well suited for positioning systems that require repeatable motion during frequent starts, stops, and load changes. Position and velocity signals exit through the feedback channel so the connected drive can monitor rotor motion during closed-loop operation.
This motor belongs to size 112 with a B-length stator and uses winding code 024. It mounts to a machine frame through a 192 mm flange and centers on a 130 mm pilot. A plain shaft with an installed shaft seal couples the load, while the power connector is oriented to the right for simpler cable routing. Continuous stall torque reaches 28.0 Nm, and thermal balance is maintained by liquid cooling that circulates through the housing. The enclosure carries a IP65 rating, and insulation is class F for 155 °C winding protection. A digital servo feedback unit with an integrated optical encoder delivers position data, and overall system accuracy is rated at ±0.5 angular minutes.
An internal holding brake supplies 22.0 Nm of static torque, allowing the axis to remain fixed during power loss or when the drive is disabled. Environmental limits include a storage range of -20 to +80 °C, an operating window of 0 to 40 °C, and a maximum installation altitude of 1000 m above mean sea level. Position detection is absolute (>4096 revolutions), so homing after startup is unnecessary. The encoder uses an optical measurement principle, and the shaft seal helps block fluid ingress during liquid-cooling operation.
