Product Description:
The MHD112D-027-NP3-AN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MHD Synchronous Motors series. This motor converts drive commands from a Rexroth controller into precise rotary motion for automated axes, material-handling stations, and machining centers. It uses a relative position detection scheme supported by an integrated digital servo feedback encoder so the controller can track rotor angle in real time. Liquid circulation through the housing removes heat, allowing sustained operation at rated loads in closed-loop industrial environments. This arrangement supports accurate speed and position control during repeated starts, stops, and directional changes.
A centering shoulder of 130 mm aligns the stator on the machine frame, and the rectangular flange spans 192 mm for bolt-pattern compatibility with other 112-frame units. The 112 size code and D length code provide enough active iron for a continuous standstill torque of 48.0 Nm. Heat generated at this load is removed by the motor’s integrated liquid cooling jacket, so external airflow is unnecessary. Torque is transmitted through a keyed shaft that is protected by a dedicated shaft seal to help limit the ingress of coolant or lubricant. The centering shoulder and flange help maintain stable alignment when the motor is mounted to a machine frame or coupled to a driven load.
Electrically, winding code 027 sets the phase resistance and inductance expected by Rexroth power modules. The high-speed digital servo feedback (HSF) device reports incremental counts to the drive, while the motor’s internal electronics maintain the home offset through the same feedback link. The position information is relative rather than absolute. During a power loss or emergency stop, a spring-applied brake can hold up to 70.0 Nm at the shaft to secure vertical or suspended loads. Power leads exit toward side A through an output connector, which simplifies cabinet wiring and leaves the opposite face clear for coolant manifolds. This routing keeps the electrical connection separate from the cooling connections.
