Product Description:

Bosch Rexroth Indramat builds the MHD115A-024-PG1-BA in its MHD Synchronous Motors series. This servo motor, with winding code 024 and frame size 115, is used as a direct drive for industrial axes where precise velocity and position control are required. A digital servo feedback encoder is integrated, and it delivers absolute multi-turn data so the controller can maintain orientation even after power loss. The plain shaft configuration with an internal seal supports couplings that rely on a smooth journal while protecting the front bearing from coolant or dust ingress.

The motor provides a continuous standstill torque of 32.0 Nm, which it can hold indefinitely within its rated thermal envelope. For static holding during shutdown, the spring-applied brake supplies 70.0 Nm of torque. The enclosure meets IP65, so internal components remain protected against dust and low-pressure water jets. A square flange measuring 192 mm aligns with standard IEC layouts, and the encoder supports an overall positioning accuracy of ± 0.5 angular minutes. These features allow tight, repeatable indexing in material transfer, filling, and pick-and-place stations.

Mounting is simplified by a centering pilot of 180 mm, and the motor relies on natural convection through its ribbed housing rather than external fans. The encoder stores position in an absolute (>4096 revolutions) format, so no homing routine is needed after power restoration. Rated operation is permitted in ambient air from 0 to 40 °C; storage is allowed down to −20 °C and up to 80 °C, and class F insulation tolerates the associated winding temperatures. Installation heights can reach 1000 m above mean sea level without derating. Power is routed through an output connector on side B. The motor has length A.
