Product Description:

The MDD090A-N-020-N2M-130PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for integration with digital drive controllers, the unit converts commanded current into controlled rotary motion for positioning and velocity tasks on automated machinery such as packaging stations, pick-and-place axes, and transfer lines. This motor is part of a product family with the same mechanical interface and electrical feedback conventions, so related models use consistent mounting geometry and cabling layouts across automated equipment. That consistency helps maintain predictable installation requirements in multi-axis systems.

With a continuous standstill torque of 3.7 Nm, the motor can hold or slowly move loads without overheating when locked in position. Its rated mechanical output reaches a nominal speed of 2000 rpm, a value that aligns with typical machine tool spindle and conveyor requirements. Rotor position is resolved by an integrated multi-turn absolute encoder, enabling the controller to recover the shaft angle after power loss and removing the need for homing routines. The centering shoulder measures 130 mm, which provides the pilot fit diameter that aligns the housing to the machine frame. All power, brake, and feedback conductors exit on the right side, simplifying cabinet design when drives are arranged in linear rows.

Application security is improved by an internal blocking brake that supplies 6.5 Nm of static holding torque to help prevent vertical axes from drifting when the system is de-energized. Mated circular connectors provide a compact electrical interface, and the designated power interface uses a connector that locks with a quarter-turn. Motion feedback to the drive is transmitted as digital servo feedback, supporting high-resolution commutation and rapid current loops. A factory-installed shaft seal guards the front bearing against coolant splash and dust intrusion, allowing the motor to operate in general-purpose industrial enclosures without additional protective covers.
