Product Description:

The MDD090A-N-020-N2M-110PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides rotary motion that is tightly synchronized with drive signals, enabling precise position and speed control on automated axes. When matched with compatible drives, the unit delivers closed-loop torque for indexing tables, gantries, transfer systems, and other machinery where repeatable motion and compact installation are required.

At standstill the motor can supply 3.7 Nm continuously. This rating indicates the maximum holding or low-speed torque without overheating. Its nominal operating speed of 2000 rpm aligns with typical feed-axis requirements and sets the base electrical frequency used by the drive. A machined centering shoulder of 110 mm aligns the frame to gearboxes or machine plates, while standard housing and balancing values keep vibration within normal limits for size 090 and length code A. Power and feedback conductors exit on the left side because the connection hardware is oriented that way, and the motor uses a connector termination so wiring can be disconnected without disturbing the housing. The left-side orientation simplifies cable routing in tightly packaged cabinets.

The internal sensing architecture uses digital servo feedback (DSF) from an integrated multiturn absolute encoder, allowing the drive to recover absolute rotor position after power cycling without homing moves. A keyway shaft and a standard single-ended shaft design on side A simplify coupling to pulleys or couplings, while the opposite face remains closed. Mechanical sealing is enhanced because the unit ships with a shaft seal, which helps prevent lubricant migration along the journal. The motor is supplied without a blocking brake, so systems that require passive holding must rely on external clamping or drive torque.
