Product Description:

The MDD090A-N-020-N2L-110PB2 is a synchronous servo motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is intended for use with digital drive controllers, where it converts commanded current into precise rotary motion for positioning and speed-regulated axes in automated machinery. Its mechanical layout, shaft interface, and feedback arrangement are matched to Indramat drive systems used in assembly equipment, packaging stations, and general material handling installations. This allows the paired inverter to regulate motion accurately during acceleration, deceleration, and steady-speed operation. The motor also uses standard balancing and a standard housing, which support stable rotation and protect the stator in compact machine layouts.

Its mounting interface includes a centering diameter of 110 mm that aligns the flange with machine frames or gearboxes. Power and feedback exit through a molded connector, which keeps the external wiring grouped at one connection point on the housing. At standstill, the motor can deliver 3.7 Nm of continuous torque, and the windings support a nominal shaft speed of 2000 rpm. Positional data return to the drive through digital servo feedback (DSF), allowing closed-loop speed control and commutation without an external encoder. This arrangement supports precise axis response in applications that require consistent motion control.

Connections are located on side B, leaving the drive end clear for coupling to the machine. The output uses a keyway shaft with a factory-installed shaft seal that helps limit dust or oil ingress along the journal. An integrated blocking brake provides 11.0 Nm of holding torque when power is off, which is useful on vertical axes or other loads that must remain in position at rest. The motor is built in frame size 090 with length code A, and the rear end does not include a secondary shaft extension. That shorter rear profile helps preserve space behind the motor in tightly packed installations.
