Product Description:

The MDD090B-N-020-N2M-130GR2 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it serves as the rotary actuator in closed-loop servo axes used on machine tools, printing lines, and packaging stations. When paired with a compatible amplifier, the motor converts commanded current into controlled motion for precise positioning and regulated speed. This arrangement allows automated equipment to coordinate multiple axes during cutting, feeding, indexing, and material transfer tasks.

The flange has a centering diameter of 130 mm, which helps align the stator housing accurately with the machine frame. Power and feedback conductors exit on the right side, which can simplify cable routing when the machine layout keeps connections on one face. At standstill, the motor delivers 7.2 Nm of continuous torque, allowing it to hold or slowly index loads without overheating under rated conditions. The motor reaches a nominal speed of 2000 rpm, giving the connected drive a practical operating range for general servo applications. Rotor position is reported by an integrated multi-turn absolute encoder, so position information remains available after power cycling and the control system can restore axis location without a separate reference move.

For dynamic stops, the blocking brake supplies 11.0 Nm of torque, which helps prevent vertical or inertial loads from drifting when drive power is removed. Feedback signals are transmitted as Digital servo feedback (DSF), supporting high-resolution position data and stable closed-loop response. The length designation B indicates the second stator stack within the 090 frame and supports a balanced combination of torque output and overall motor size. The motor uses a plain shaft, so couplings or pulleys mount without a keyway, and the installed shaft seal helps limit the entry of dust or coolant at the bearing area.
