Product Description:

The MDD090B-N-020-N2M-110PL0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is classified as a motor for digital drive controllers and converts commanded current into regulated torque for positioning axes and conveyor sections on automated lines. The size 090 frame and length code B keep the assembly compact while still supplying the inertia needed for medium payloads. A standard housing simplifies integration with protective machine enclosures and supports use in tightly arranged equipment layouts.

At locked rotor, the motor can deliver a continuous torque of 7.2 Nm, enabling static load support without overheating. Under rated electrical conditions, the shaft reaches 2000 rpm, a speed suited for pick-and-place devices and moderate-speed spindles. Accurate mechanical registration is provided by a centering pilot of 110 mm, allowing repeatable flange alignment against gearboxes or mounts. Power and feedback cables exit on the left side through a shielded connector, helping route wiring away from moving parts. Motion feedback is provided by an integrated multiturn absolute encoder, so the controller receives position data over multiple revolutions without a homing sequence. The standard housing, single-sided shaft end, and keyway interface suit common modular machine layouts.

The front bearing region is sealed with a shaft seal, which reduces lubricant loss and helps keep dust or coolant out of the housing. Because the design is without a blocking brake, holding torque during power loss must be supplied by the drive amplifier or an external clamp. Rotor manufacturing uses standard balancing, which helps keep vibration low at nominal speed. Position and speed signals are transmitted through digital servo feedback (DSF), and the keyway shaft transfers torque to couplings or pulleys.
