Product Description:

The MDD065C-N-040-N2L-095GB0 is a synchronous motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drives in industrial automation, it provides controlled torque and speed for axes that require precise electronic regulation. It is well suited for conveyors, index tables, feeder modules, and other equipment that depends on repeatable starts, stops, and speed changes. The permanent-magnet design supports consistent motion in compact machine layouts where stable response is important.

At its rated operating point, the motor delivers a continuous standstill torque of 2.1 Nm, giving stable low-speed output without excessive heating. When operated with a matched inverter, it reaches a nominal speed of 4000 rpm to support rapid indexing and short cycle times. A centering diameter of 95 mm helps align the motor accurately during mounting, and the conductors exit on side B through a sealed industrial connector. A shaft seal helps protect the bearings from oil mist, while the aluminum housing supports convective cooling. This operating range suits axes that alternate between holding force at low speed and faster commanded motion during normal machine operation.

Closed-loop accuracy is maintained by digital servo feedback, which returns position data to the drive during operation. The motor uses length code C within the 065 frame, giving it the active stack length used for this size. The unit is supplied without a blocking brake, so holding torque must come from the drive or from external machine hardware when the axis is stopped. It also has a plain shaft in a single-ended layout, which simplifies coupling to pulleys or similar drive components. The feedback system allows the connected drive to monitor rotor position continuously so speed and position loops remain stable during changing loads.
