Product Description:

The MDD090A-N-030-N2M-110PL0 is a synchronous AC servo motor built by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated machinery where precise position and velocity control are required. By coupling directly to loads such as indexing tables, pick-and-place axes, or light-duty gantry drives, the motor converts electrical energy from the drive into controlled mechanical torque, forming a closed-loop axis within larger industrial automation cells.

The motor delivers a continuous standstill torque of 3.7 Nm, permitting steady holding force on static loads without thermal overload. Under rated excitation, it reaches a nominal speed of 3000 rpm, allowing rapid point-to-point moves while maintaining synchronism with the inverter’s command frequency. A centering diameter of 110 mm gives a precise pilot fit to machine frames and simplifies coaxial alignment during installation. Power and feedback are routed through a connector, and the motor uses a keyway shaft to prevent slip when reversing torque direction. Servo position data travels over digital servo feedback (DSF) signals so the drive can correct any deviation in real time.

A built-in integrated multi-turn absolute encoder reports absolute mechanical position over multiple revolutions, eliminating homing sequences after power cycles. The unit operates without a blocking brake, so external brakes or drive torque must secure vertical axes during shutdowns. The front bearing region is fitted with a shaft seal, and the power and feedback socket face is oriented to the left, easing cable runs in cabinets arranged on the motor’s right side. The rotor is factory balanced to the standard grade, the housing follows length code A, and the shaft end is supplied only on side A to reduce mass and inertia.
