Product Description:

The MHD112D-024-NP2-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It provides closed-loop rotary motion for industrial axes that need stable speed and precise positioning. The unit couples directly to gearboxes or pulleys, converting drive current into mechanical torque with repeatability. Its keyed shaft and integrated holding brake simplify installations where rapid stops and secure load retention are required. Because it is a synchronous servo motor, it responds quickly to commanded changes in speed and position when paired with a compatible drive. This makes it suitable for feed axes, transfer stations, and other machine motions that require repeatable starts and stops.

At standstill, the rotor delivers a continuous torque of 48.0 Nm, allowing the axis to hold heavy loads without overheating. A centering diameter of 130 mm and a 192 mm square flange locate the housing on machine frames. The enclosure is rated IP65, so it is dust-tight and resists water jets. Heat is removed by liquid cooling, keeping the windings within limits while the motor runs in an ambient range of 0 to 40 °C. Position data return through digital servo feedback (HSF); this optical device supplies relative position updates for closed-loop control. The keyed shaft includes a seal to help prevent fluid ingress, and power leads exit on side B through an output connector to simplify cable routing. The flange geometry also provides a rigid mounting face for machines that need accurate alignment between the motor and the driven load.

The integrated holding brake applies 32.0 Nm of static torque to secure vertical axes when power is removed. Combined with a system accuracy of ± 0.5 angular minutes, the motor maintains precise orientation after each stop. Windings built to class F insulation withstand higher thermal stress, and the electrical design is identified by winding code 024, which indicates the motor’s electrical configuration for use with suitable drive controllers. During storage, the unit tolerates temperatures from −20 to +80 °C, and it can be installed up to 1000 m above mean sea level without derating. The brake and feedback arrangement support controlled restarts after stop conditions without losing the commanded orientation.
