Product Description:

The MDD090C-N-020-N2L-110PR2 is a synchronous AC servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into proportional shaft torque and speed for precise axis control in automated machinery and handling systems. Its single-ended shaft and integrated position transducer support closed-loop operation with compatible Rexroth drive electronics. This makes the motor suitable for packaging, printing, and other motion platforms that require accurate speed regulation and repeatable positioning.

At standstill, the motor supplies 10.4 Nm of continuous torque, and it can reach a nominal speed of 2000 rpm when operated with the appropriate drive. Rotor balance is standard, which suits general machine assemblies in this frame size. The centering register measures 110 mm, helping the housing seat concentrically on a mating flange. Position and velocity data are returned through digital servo feedback, allowing the controller to monitor motor movement continuously during operation. Cables exit on the motor’s right side because the power and feedback ports are located on that side of the stator housing.

The motor is delivered with a blocking brake that secures the rotor when power is removed, and the brake can hold up to 11.0 Nm of static load. Electrical power and encoder connections are routed through a single connector, which keeps the interface compact. The output shaft uses a keyway and includes a shaft seal to help limit lubricant migration from a connected gearbox. A standard housing protects the windings, and the design omits a side B shaft end to reduce rearward space requirements. The stator stack uses length code C, which suits applications that need moderate torque density without increasing the overall frame size.
