The Bosch MPN R911314978 (MHD112A-024-PP2-BN) is a synchronous servo motor designed for closed-loop feedback operation, utilizing a digital multi-turn absolute encoder (>4096 revolutions) for precise position detection. The motor incorporates a keyed shaft with sealing ring and features an integrated holding brake rated at 32 Nm. It supports both natural convection and surface cooling, achieving a continuous standstill torque of 15 Nm (60K overheat) or 17 Nm (100K overheat) with convection, and 22.5 Nm (60/100K overheat) with surface cooling. The housing supports liquid cooling, and the motor has a centering diameter of 130 mm, flange size of 192 mm, and motor size of 112. Power is delivered via a lateral output connector (direction to side B), and a separate feedback cable is used for encoder integration.
