Product Description:

The MDD093C-N-040-N2M-130PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive output into precise rotary motion for positioning axes, feed drives, or auxiliary tasks in automated machinery. The design pairs the stator windings with permanent-magnet excitation so speed and torque can be modulated directly by the controller in closed-loop operation, making the unit suitable for repetitive, high-cycle industrial motion profiles.

The mechanical envelope is aligned with a centering diameter of 130 mm, allowing direct mounting on gearboxes or machine frames without additional adapters. Power and feedback cables exit on the right side through a sealed connector interface, which helps keep routing orderly in compact installations. Internal rotor balancing remains standard to minimize residual vibration, and the housing follows a standard motor configuration. Nominal operation is specified at 4000 rpm, giving fast traverse rates when paired with rapid-response drives. The motor size is 093, and length code C provides a longer active stack for higher continuous power. An integrated blocking brake provides a static holding torque of 11 Nm when power is removed.

Position feedback relies on an integrated multi-turn absolute encoder, which reports absolute rotor angle over multiple revolutions and removes the need for homing after shutdowns. Feedback signals are transmitted as digital servo feedback (DSF), matching compatible Rexroth drive interfaces. A dedicated shaft seal surrounds the output end to limit lubricant leakage and particle ingress in contaminated environments. Torque is transferred through a keyway connection that helps prevent slip under cyclical loads. The motor uses a standard single-ended shaft with a keyway shaft arrangement, while the connector format allows quick disconnection during service.
