Product Description:

The MDD090A-N-030-N2M-110PB0 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies rotary motion for positioning axes and cyclic transport stages in automated machinery. This type of motor is suited to applications that require repeatable motion, stable speed control, and accurate response during frequent starts, stops, and reversals.

A centering pilot of 110 mm aligns the housing to machine frames, helping the motor seat accurately during installation. The motor delivers a continuous standstill torque of 3.7 Nm, which allows the drive to maintain holding force during stationary operation. During motion, the rotor can reach a nominal speed of 3000 rpm, supporting moderate operating speeds in indexing systems and transport axes. Power is transmitted through a keyway shaft, and the motor uses a single shaft extension while the opposite side remains closed to accommodate the internal encoder. The 090 frame size and A length keep the housing compact, and standard balancing helps limit vibration during high-speed cycles.

Position data come from an integrated multiturn absolute encoder that works with the drive’s Digital servo feedback (DSF) channel for closed-loop operation and immediate position reporting. Power and signal leads exit on Side B, which can simplify cable routing when the driven load is on the opposite end of the motor. A shaft seal protects the internal bearings from splash and dust during normal machine use. The motor is supplied without a blocking brake, so holding and stopping force must be provided by the drive or by external mechanical means. Electrical connection is made through a circular connector used for this motor series.
