Product Description:

The MDD090C-N-040-N2M-130PA0 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Delivered for use with digital drive controllers, it is deployed in automation stations that need closely controlled rotational motion for axes such as gantries, tool heads, or indexing tables. The unit converts the regulated three-phase output of a servo inverter into repeatable torque and speed, while its electronic feedback supports precise closed-loop positioning.

A centering diameter of 130 mm helps align the motor flange with the machine housing. Cables exit on side A, and a single circular connector combines power, encoder, and ground conductors to simplify installation. Using one connector reduces cable handling at the housing and keeps the motor interface compact. At standstill, the rotor can deliver 10.4 Nm continuously. Position data are generated by an integrated multi-turn absolute encoder that maintains shaft angle across power cycles. A standard balancing grade and the normal housing for this series keep vibration and thermal behavior consistent for the 090 frame.

The motor has a nominal speed of 4000 rpm, which sets the continuous operating speed range before field weakening is required. A machined keyway on the output shaft transmits torque to couplings, and an axial shaft seal helps prevent oil or dust from entering the stator air gap. Feedback and drive synchronization are handled through digital servo feedback (DSF), allowing high-resolution motion control through the same motor interface. The C length code provides additional active stack length, the motor size remains 090, and only the drive-side shaft is present, leaving no extension on side B. Because the product is supplied without a blocking brake, any application that must hold position during power loss requires an external mechanical restraint.
