Product Description:

The MHD112C-024-NG2-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This permanently excited unit converts controlled three-phase power from an inverter into rotational motion for positioning, conveying, or forming axes in automated machinery. It is supplied with an integrated holding brake and a plain shaft, so mechanical load can be secured at standstill and driven directly without keys or splines. In typical machine installations, it works with a matching drive controller that regulates current, speed, and rotor position through closed-loop feedback.

At standstill the motor sustains 38.0 Nm of torque, and heat is removed by liquid cooling through the built-in cooling jacket. Housing joints and the output shaft seal combine with an IP65 enclosure rating to block dust and water jets. The mounting interface uses a 130 mm centering diameter and a 192 mm square flange, allowing interchange with other 112-frame drives. The motor uses winding code 024 and operates without derating from 0 to 40 °C. An optical encoder with digital servo feedback HSF provides relative position data for the drive controller, and power cabling exits through an output connector on side B.

The built-in brake develops 32.0 Nm of holding torque, enabling vertical or overhung loads to remain fixed when the inverter is de-energized. Class F insulation permits winding temperatures up to 155 °C, while the plain shaft with a positive shaft seal helps prevent lubricant escape. The motor can be installed up to 1000 m above mean sea level, and storage temperatures range from −20 to +80 °C. The housing has C length for this frame size. Because the feedback is relative rather than absolute, the axis uses homing after power-up instead of absolute multi-turn tracking.
