Product Description:

The MDD090A-N-020-N2M-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Its size code 090 and length code A give it a compact frame for installations with limited mounting space while still providing the torque needed for medium-duty axes. Designed for digital drive controllers, it converts regulated AC power into precise rotary motion for pick-and-place modules, indexing tables, and other position-controlled stations. This operating principle allows the motor to support closed-loop motion tasks where repeatable speed and position control are required.

At standstill, the rotor can exert 3.7 Nm of continuous torque without exceeding thermal limits, and the rated operating speed reaches 2000 rpm, giving the drive a broad constant-torque range. Accurate mechanical registration is supported by the 110 mm centering diameter, which locates the motor concentrically on the machine frame. Power and feedback conductors exit through a connector on side B, which can help reduce cable bends in vertical installations. A plain shaft transfers torque directly to couplings or pulleys, and the motor uses standard dynamic balancing to limit residual vibration during rotation. The housing is the standard version, so mounting dimensions match other motors in the series.

Position data is supplied by the integrated multiturn absolute encoder, and the signals return to the drive through digital servo feedback for precise electronic commutation and position control. Multiturn feedback also preserves position information across multiple revolutions, which supports axes that travel beyond a single turn. The output shaft uses a shaft seal, which helps limit the entry of contaminants from adjacent mechanical components. The motor is supplied without a blocking brake, so static holding torque must come from the drive or an external clamp when the axis is stopped. It has a single shaft end, and the connector-based cable interface keeps the electrical connection compact.
