Product Description:

The MDD090A-N-020-N2M-130PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It serves as the rotary actuator for digital drive controllers, converting commanded current into precise shaft motion for positioning, feed, and handling axes in automated machinery. This motor is intended for closed-loop operation, where accurate response to speed and position commands is important. Its compact 090 frame suits machine layouts that need dependable motion without excessive installation depth.

A mounting centering diameter of 130 mm matches standard mechanical interfaces. The motor provides a continuous standstill torque of 3.7 Nm, so it can hold rated load at zero speed without overheating under normal conditions. The rotor reaches a nominal speed of 2000 rpm, giving a practical balance of speed range and torque output for medium-inertia axes. Electrical terminations are oriented to the right side and use a sealed connector, which keeps cable routing orderly in compact installations. The unit is supplied without a blocking brake, so any load that must remain fixed after power removal requires external holding. Balancing and housing execution are standard for this frame size.

An integrated multiturn absolute encoder retains position information through power cycles, which helps the control system recover axis position after restart. Position data is transmitted through digital servo feedback, allowing the controller to compare commanded and actual motion continuously during operation. A built-in shaft seal helps limit contaminant ingress at the shaft exit, and the keyway shaft end supports direct coupling to pulleys or gears. The A motor length keeps overall depth low, while the single-ended shaft without a side-B extension leaves more room around the driven end for nearby machine components.
