Product Description:

The MDD090A-N-020-N2M-110GL2 is a three-phase permanent-magnet servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it converts controlled stator currents into mechanical motion for positioning or velocity-regulated axes in industrial automation. A standard housing encloses the stator package, and the unit mounts to machinery through its centering pilot for direct coupling to gearheads or load shafts.

This model sustains a continuous standstill torque of 3.7 Nm, giving the drive system steady low-speed holding capability during closed-loop operation. When power is removed, a blocking brake rated at 11.0 Nm secures the shaft against back-driving forces. The rotor can reach a nominal speed of 2000 rpm, matching applications that require moderate dynamic response while minimizing bearing wear. A centering diameter of 110 mm provides a rigid seating surface that keeps radial runout low, and position data are generated by an integrated multi-turn absolute encoder so the controller can recover the exact shaft angle after a power cycle or emergency stop. Electrical and feedback cabling terminates through a keyed connector interface, and the detachable plug allows connection without cabinet rewiring.

The motor's electrical connections exit on the left side, which helps route cables away from moving links. Motion feedback uses Digital Servo Feedback, transmitting position and velocity data to compatible drives over a shielded pair. A fitted shaft seal blocks coolant spray and fine dust from entering the front bearing, and the plain output shaft follows size code 090 for inertia pairing with medium load masses. Standard dynamic balancing reduces vibration at rated speed, while the A-length stator stack lowers mass for axes where weight on the machine bridge must be minimized. A single-ended shaft without a side B extension leaves room on the back for the brake assembly and connector set.
