Product Description:

The MHD112C-024-NG3-LN is a three-phase servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is installed between a power inverter and the mechanical load, converting regulated AC into precise rotary movement for gantries, printing cylinders, and similar automated axes in industrial plants. When paired with a compatible servo drive, it supports repeatable positioning, speed regulation, and controlled acceleration during automatic machine cycles. The size 112 stator uses winding code 024 and a C-length body with a 192 mm square flange, giving the motor a fixed mounting format and matched electrical layout.

The motor can deliver a continuous standstill torque of 38.0 Nm, and the housing uses liquid cooling to carry heat away from the copper windings. Active cooling helps the motor maintain stable thermal performance during heavy low-speed duty, where self-ventilation is limited. The enclosure is rated IP65, which protects the shaft area and the left-side power connector against dust and water jets. Rotor position is monitored by Digital servo feedback (HSF) with an optical measurement method and relative position evaluation for high-speed control loops. Closed-loop accuracy is specified at ± 0.5 angular minutes, giving the drive precise position data for commutation and motion control.

For stationary holding, the integrated brake provides 70.0 Nm of torque and includes a mechanical release feature. Storage conditions range from -20 to +80 °C, while the permissible operating ambient spans 0 to 40 °C. The permitted installation altitude is up to 1000 m above sea level. A centering diameter of 130 mm simplifies alignment to precision gearboxes or adapter plates, and the plain shaft can be paired with keyed or clamped couplings. A shaft seal is fitted to help retain lubricant and reduce contamination at the drive end.
