Product Description:
The MDD090C-N-020-N2M-130PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where closed-loop speed and position control are required in automated machinery and material-handling cells. As an electromechanical actuator, the motor converts drive current into rotary motion that can be coordinated precisely with other axes in an industrial automation sequence. This operating role makes it suitable for applications that need repeatable motion, controlled acceleration, and consistent position tracking during cyclic machine movements.
The motor reaches a nominal speed of 2000 rpm, which is its rated operating speed under normal load conditions. At standstill, it can deliver 10.4 Nm of continuous torque, providing steady force for holding and low-speed positioning tasks. A holding brake rated at 11.0 Nm locks the shaft during power-off conditions to help prevent back-driving on vertical or suspended loads. Mechanical alignment on mounting flanges is guided by a 130 mm centering diameter, which helps keep couplings and mating parts concentric during installation. Motion feedback is provided through digital servo feedback, allowing the controller to monitor rotor position in real time and maintain stable closed-loop response.
An integrated multi-turn absolute encoder reports both speed and multi-revolution position data, so the motor can return to operation without a homing routine after power cycling. The shaft uses a keyway for torque transfer through standard keyed hubs, and the housing uses length code C to balance thermal mass with installation space. Rotor vibration is limited by standard balancing, which helps the motor run smoothly with couplings and pulleys at normal operating speed. Wiring exits through a sealed connector on the right side, while a shaft seal and the housing protection help keep airborne oil mist and fine dust away from internal components. The motor also has frame size 090 and a single-ended shaft, which fit compact servo installations and common machine drive layouts.
