Product Description:

The MDD090B-N-020-N2M-110GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It functions as a permanent-magnet actuator for digital drive controllers, supplying closed-loop torque and velocity to machine tools, packaging lines, and handling equipment. Its electromechanical design lets machine builders obtain high positional accuracy while maintaining compact installation dimensions. Because it is intended for servo operation, the motor responds quickly to drive commands and supports repeatable motion in cyclic industrial processes.

Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, allowing moderate-speed axes to run without gearbox multiplication. At standstill, the winding can sustain a continuous torque of 7.2 Nm, so static loads such as clamped workpieces or vertical masses can remain supported indefinitely. A factory-installed blocking brake delivers up to 11.0 Nm of holding torque and engages automatically when the drive is disabled to prevent drift. For streamlined cabinet wiring, all power, brake, and feedback conductors exit on Side A, and a single industrial a connector provides the mating interface. This arrangement keeps the motor connections grouped on one side, which can help when cable routing space is limited.

A centering collar of 110 mm provides a close fit in aligned housings and helps position the motor accurately during mounting. Rotor balance is graded as standard, and the aluminum housing is likewise marked standard for heat transfer. Motion data are transmitted through digital servo feedback generated by the integrated multi-turn absolute encoder, so the controller retains position information through power interruptions. Output torque is delivered through a plain shaft sealed against contamination, and an additional shaft seal helps limit lubricant escape. The housing uses size code 090 and length code B for the overall package length and flange pattern.
