Product Description:

The MDD090A-N-020-N2M-130PB2 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts commanded electrical power into rotational motion for positioning tasks in automated machinery. Its role is to provide closed-loop speed and torque control in assembly cells, material-handling axes, and other industrial stations that rely on precise servo performance.

This model delivers a continuous standstill torque of 3.7 Nm, giving machines enough holding force for static loads without overheating. Under rated excitation, it reaches a nominal speed of 2000 rpm, which suits moderate-speed applications where accuracy is more important than very high rotational speed. The centering diameter of 130 mm aligns the motor housing with adjacent mechanical components and helps maintain concentricity with gearboxes or couplings. Motion feedback is supplied through digital servo feedback (DSF), and position data is resolved by an integrated multiturn absolute encoder; together, these devices provide the drive with real-time rotor angle information for stable control. The motor has size 090 with length code A, and standard balancing helps reduce vibration at rated speed.

Cabling exits on side B so wiring can be routed away from moving hardware, and a keyed connector simplifies cable attachment. A blocking brake is built in, and its static holding capability reaches 11.0 Nm, which allows vertical axes to remain fixed during power loss. There is a shaft seal that helps block oil or dust from entering the bearing chamber, and the keyway shaft supports positive mechanical engagement with pulleys or couplings. The motor also has a standard housing, a standard shaft end without a second output, and normal balancing.
