Product Description:

The MHD112A-024-PP0-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It provides closed-loop rotary actuation for CNC axes, pick-and-place gantries, packaging machines, and similar automated equipment where high positional repeatability and consistent torque are required through changing load conditions. By integrating a digital feedback encoder, the unit supports precise speed and position control when paired with compatible Indramat drive controllers and used on axes that demand repeatable motion during frequent starts, stops, direction changes, and short cycle times.

For mechanical integration, the rotor seats against a centering pilot of 130 mm, and the matching 192 mm square flange fastens directly to standardized machine frames for accurate alignment during installation. The shaft can supply 15.0 Nm of continuous torque at standstill, a value sustained by the internal liquid cooling jacket that transports heat away from the windings during continuous duty. An enclosure rating of IP65 blocks dust ingress and low-pressure water jets during operation. Position and velocity are sampled by an optical digital servo feedback encoder, providing absolute data beyond 4096 revolutions and reducing the need for repeated homing after power cycles. The motor is supplied without a holding brake, reducing mass for highly dynamic axes. Electrical power is connected through a connector on side A, and winding code 024 matches the electrical characteristics expected by compatible Rexroth drives.

The motor operates reliably at ambient temperatures from 0 to 40 °C, retains insulation class F for 155 °C winding capability, and may be installed up to 1000 m above mean sea level without derating. Storage is allowed from -20 to +80 °C, so the motor can be kept in inventory without special climate control before installation or after removal from service. The output shaft uses a keyed shaft design and a shaft seal to keep lubrication in and contaminants out. The feedback circuit supports system accuracy of ±0.5 angular minutes. The compact A-length stator on the 112 frame size helps support fast acceleration during indexing, interpolation, and frequent reversals on compact machine axes.
