Product Description:

The MDD090C-N-020-N2M-130PB2 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for integration with digital drive controllers in the MDD Synchronous Motors series. In automated machinery, the unit converts commanded current into rotary motion so axes can be positioned or regulated with high accuracy in packaging lines, printing presses, and material-handling modules. Its brushless design supports closed-loop motion tasks that require repeatable speed control and precise positioning. When paired with a compatible controller, it also supports synchronized movement in indexing, feed, and transfer applications where stable response is important.

The motor uses a 090 frame and has a centering diameter of 130 mm, which helps align the rotor with gearboxes or mounting brackets. At standstill, it can supply 10.4 Nm of continuous torque, so the drive can hold a steady load without overheating during sustained operation. Under rated conditions, the rotor reaches 2000 rpm, allowing smooth velocity control on medium-speed axes. A blocking brake at the non-drive end produces 11.0 Nm of holding torque, which helps prevent unintended movement when power is removed. The motor has a standard housing and a C-length body, giving it a mid-range size that balances inertia and heat dissipation.

Electrical and signal leads exit on Side B, which can simplify cable routing when the motor is mounted with drive electronics on the same face. The molded connector combines power, brake, and feedback circuits into one plug, reducing the number of separate connections at the motor. Position information from the integrated multiturn absolute encoder is delivered as Digital servo feedback, giving the controller exact shaft angle over multiple revolutions without requiring homing after power loss. The output shaft uses a keyway profile to secure pulleys or couplings, and the design omits a second shaft end to save space. A permanent shaft seal helps protect the bearings from debris during operation.
