Product Description:

The MHD093C-035-PG1-BN/S020 is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop motion axes where fast response, repeatable positioning, and continuous duty are required. The integrated encoder delivers digital servo feedback so the drive can regulate torque and speed without external sensors, and the housing is prepared for liquid circulation to remove heat generated during sustained operation.

A centering pilot of 130 mm keeps the stator concentric with the machine frame, limiting radial misalignment that would raise bearing load. The motor can supply 23.0 Nm of continuous standstill torque, which indicates its ability to hold a load without motion while current flows through the windings. Heat from this operating point is extracted by liquid cooling, permitting higher power density than an air-cooled housing. The mounting interface follows a 140 / 150 mm square flange pattern, simplifying interchange with other IEC-sized motors in the same cell. A plain shaft is provided so couplings or timing pulleys can be installed without keyways, reducing stress concentrations on the hub.

For power-off retention, the electromagnetic brake supplies 22.0 Nm of holding torque, allowing suspended or vertical loads to remain stationary once mains power is removed. Absolute position feedback over more than one mechanical turn is available through the encoder’s absolute (>4096 revolutions) tracking capability, eliminating homing sequences after startup. Motor power leads exit the housing on side B, an orientation that helps route cables away from gearboxes or coolant manifolds, and termination is through an output connector for quick exchange during service. A shaft seal is fitted to limit ingress when the liquid jacket operates under elevated humidity, and the C-length stator with winding code 035 matches drive inverters that supply the required current and voltage profile for dynamic industrial cycles.
