Product Description:

The MDD090C-N-030-N2L-110PB1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified for use with digital drive controllers, it converts commanded current into regulated mechanical rotation for mid-range automation axes. The motor has frame size 090 and length code C, which correspond to its stack height and overall shaft length. A blocking holding brake is integrated for position retention, and the standard single-ended shaft supports coupling to gearboxes or pulleys. The housing uses standard balancing, which helps the motor run smoothly in repetitive motion applications. That makes it suitable for feed axes, indexing stations, and transfer mechanisms that require repeatable motion under varying load.

Its continuous stall capability reaches 10.4 Nm, allowing constant torque production during closed-loop positioning. The rotor can accelerate to a nominal speed of 3000 rpm when powered by a compatible inverter. A centering diameter of 110 mm helps align the flange to machine surfaces for coaxial load transfer. Feedback to the controller is provided through digital servo feedback (DSF), which supplies position and speed data in serial form for accurate control. Because the feedback device is integrated, the drive can monitor rotor behavior without an external measuring assembly. Power and signal conductors terminate through a sealed connector, which keeps cable routing compact and protects the connection area.

Cabling exits on side B of the stator, so the leads can be routed away from the load side of the motor. During power-off events, the integrated brake provides 6.5 Nm of holding torque to help prevent drift on vertical or indexing axes. The output shaft uses a keyway for positive torque transmission, and a shaft seal protects the front bearing area from contaminants. The brake and shaft arrangement are useful on machines that cycle frequently and must stop in a controlled position. The layout also suits installations where compact cable management and secure shaft coupling are important.
