Product Description:
The MHD112D-024-PP3-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It integrates a digital servo feedback encoder to supply absolute position data to the drive controller, allowing closed-loop motion of packaging gantries, metal-cutting spindles, and transfer axes. The unit’s keyed shaft, centering shoulder, and flange interface are dimensioned to mate directly with precision gearboxes and couplings, giving machine builders a compact source of regulated rotary torque.
At standstill, the motor delivers 48.0 Nm continuously. Liquid flow through the housing removes copper and stator heat, and the liquid cooling circuit enables full output during operation. An enclosure rating of IP65 blocks dust ingress and water jets so the motor can be mounted outside sealed cabinets. The centering diameter measures 130 mm, while the square flange spans 192 mm, providing a stable seat on machine frames. Class F insulation tolerates winding temperatures up to 155 °C, and the 024 winding code matches drives that supply the required current and voltage. The motor length is coded D, and size code 112 indicates a stator diameter that balances inertia with acceleration capability. A shaft seal protects the internal bearings, and the power leads exit toward side B through an output connector. Optical measurement inside the feedback module enhances resolution during velocity loops.
A holding brake rated at 70.0 Nm prevents back-driving when power is removed, which is useful on vertical or indexing axes. System accuracy is specified at ± 0.5 angular minutes, so commanded moves remain within a narrow positional window. The motor operates in ambient temperatures from 0 to 40 °C and may be stored between −20 and 80 °C without damage. Absolute feedback remains valid over more than 4096 revolutions, reducing homing cycles after shutdown. Installation is permitted up to 1000 m above mean sea level, and the keyed output couples directly to loads without external brakes or clutches.
