Product Description:

The MDD090A-N-020-N2M-130GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive commands into precise rotary motion for tooling, conveyors, and pick-and-place heads in automated production lines. A standard housing and balanced rotor help keep vibration within an acceptable range, and the compact A-length construction lets the unit fit directly into machinery frames where space is limited. This layout supports accurate axis movement in machines that need repeatable positioning without requiring a large motor envelope.

Its mechanical interface uses a flange with a 130 mm centering diameter, which provides a fixed reference for concentric alignment with gearboxes or couplings. Power and feedback leads exit at Side B, and a detachable connector supports straightforward cable routing in compact machine layouts. Under continuous stall conditions, the motor delivers 3.7 Nm of torque, which indicates the continuous holding capability available at zero speed. During motion, it reaches a rated speed of 2000 rpm, matching moderate-speed positioning and feed applications. The 090 frame size gives the motor a practical balance between output and overall package size for medium-duty axes.

Position information is supplied by an onboard integrated multiturn absolute encoder, allowing the drive to retain shaft position information across several revolutions after power cycling. The motor is built without a blocking brake, so any holding function must be provided through external mechanics or maintained servo torque. Feedback to the controller is transmitted as digital servo feedback (DSF), which supports precise velocity and position control without relying on analog signal transmission. A shaft seal protects the plain shaft and internal bearings from splash and dust ingress, which helps the motor operate reliably in enclosed machine spaces.
