Product Description:

The MHD115C-024-PP1-AA is a servo motor built by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It converts drive current into controlled mechanical motion for positioning tasks in automated production lines, including transfer axes, indexing stations, and similar machinery. A keyed shaft transfers torque to the load, while an integrated optical encoder supplies multi-turn absolute feedback to the controller for closed-loop operation. The housing uses a sealed design with a shaft lip seal so the motor can operate on machinery exposed to dust or coolant splash without additional covers.

This model can develop a continuous standstill torque of 70.0 Nm, giving it the ability to hold loads without overheating when motion is paused or when the axis must resist a steady load. Its enclosure meets the IP65 rating, which blocks dust ingress and water jets on open machine frames. Heat is removed by natural convection, so no external blower or liquid circuit is required. This cooling method keeps the motor self-contained and avoids the need for separate airflow hardware. Digital feedback accuracy is specified at ± 0.5 angular minutes, enabling tight positioning when the motor is paired with high-resolution drives. Windings are insulated to Class F, allowing winding temperatures up to 155 °C during operation.

The flange uses a centering pilot of 180 mm for accurate alignment, and the bolt circle fits a frame with a 192 mm square mounting pattern. The motor delivers full performance in ambient temperatures from 0 to 40 °C and at mounting heights up to 1000 m above mean sea level. Absolute position detection over more than 4096 revolutions is available through the encoder as absolute (>4096 revolutions), so homing routines are unnecessary after power cycles. A 70 Nm holding brake is included for vertical axes, and power leads exit on side A through an output connector.
