Product Description:

The MDD090A-N-020-N2M-110GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotary motion for positioning and velocity loops in automated machinery and can be paired with Rexroth inverter modules on assembly lines, packaging systems, or robotics cells. Its synchronous design supports closed-loop motion tasks that require accurate shaft positioning and stable torque response over repeated operating cycles.

For continuous operation, this model develops 3.7 Nm of standstill torque. Its rotor reaches a nominal speed of 2000 rpm at rated current. A standard housing and standard rotor balancing support stable operation during continuous duty. The flange has a centering diameter of 110 mm, and size code 090 identifies the frame used for this motor. Motor length code A indicates the shortest stator package for this diameter, which helps reduce installation depth when space is limited. An integrated multiturn absolute encoder monitors shaft position so the connected drive receives continuous position information during operation.

A blocking brake supplies 11.0 Nm of holding torque when power is removed, which helps prevent back-driving on vertical axes. All power and feedback conductors exit on the right side through a keyed connector, which supports quick cable attachment and orderly routing. Position data is transmitted as digital servo feedback (DSF), allowing the controller to process high-resolution shaft information during each control cycle. A plain shaft supports coupling to gearboxes or timing pulleys. A shaft seal helps block oil mist and fine dust from reaching the bearing area. The shaft is provided only on side A, so there is no rear shaft extension at the opposite end.
