Product Description:

The MHD112D-027-NG0-BN servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop axis control where electrical energy must be converted into tightly regulated rotary motion, such as in transfer lines, press drives, or high-speed pick-and-place units on automated assembly equipment. The motor has winding code 027, motor length D, an operating ambient range of 0–40 °C, and a power connector on side B.

At standstill, the motor can sustain a continuous torque of 48.0 Nm, enabling it to hold loads without thermal overload. Its enclosure meets the IP65 rating, so internal components are protected against dust ingress and low-pressure water jets. Position data are returned through Digital servo feedback (HSF), which supports high update rates for precise interpolation. Mechanical attachment is handled by a square 192 mm flange with a 130 mm centering diameter, allowing concentric alignment on machine frames. Heat generated by the windings is removed through liquid cooling, which keeps the stator below its thermal limit during continuous duty.

The winding system uses Class F insulation, giving the copper a permissible temperature rise that matches the liquid-cooled housing. Optical scanning of the feedback track yields a system accuracy of ± 0.5 angular minutes, supporting indexing tasks that demand sub-degree repeatability. For logistics, the motor tolerates a storage window of -20 to +80 °C, and operation is permitted up to 1000 m above mean sea level without derating. Power is transmitted through a plain shaft, and no holding brake is fitted, so external clamping or drive torque must secure the load during power-off conditions. A shaft seal is present to help prevent lubricant ingress into the housing.
