Product Description:

The MDD090B-N-020-N2L-110PR0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit delivers closed-loop velocity and position control to conveyors, tooling tables, and gantry axes. Its housing complies with the IEC IP rating and the motor is delivered in a standard length-code B frame with standard balancing so it can be installed without additional vibration isolation.

At standstill the motor produces a continuous torque of 7.2 Nm, and its mechanical output can rise to a nominal shaft speed of 2000 min⁻¹ under rated conditions. Current peaks up to 48.6 A are tolerated during acceleration, while the electromagnetic design links phase current to torque through a constant of 0.86 Nm/A. An enclosure rating of IP65 blocks dust and low-pressure water jets so the motor can sit directly on machinery in wash-down areas. Digital servo feedback (DSF) on the rear connector provides absolute position data for the controller, and right-hand power and feedback connections keep cable routing inside typical cabinet layouts.

The windings present an inductance of 10.1 mH and a resistance of 1.99 Ohm at 20 °C; together these values define the electrical time constant used when tuning current loops. Class F insulation withstands internal hot-spot temperatures up to 155 °C, while an integrated shaft seal prevents coolant ingress around the keyed shaft. A centering shoulder of 110 mm simplifies precise flange alignment, and the absence of a blocking brake means external mechanical restraints must hold vertical loads.
