Product Description:

The MDD090A-N-020-N2M-110GA2 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts commanded current into precise rotary motion for positioning and speed control in automated cells, pick-and-place modules, and CNC axes. The integrated design combines the motor, feedback system, and brake in one housing, which reduces external hardware around the axis and helps keep the installation compact. It is suited to machines that need repeatable starts, stops, and speed changes without adding separate position devices or holding components.

During rated operation, the shaft reaches 2000 rpm, enabling synchronization with moderate-inertia loads and routine cycle timing. The stator provides a continuous standstill torque of 3.7 Nm, so the axis can maintain commanded force at zero speed during controlled holding. A factory-installed blocking brake supplies 11.0 Nm when power is removed to help prevent unintended movement. Power and feedback conductors exit on side A, which can simplify cable routing when the flange faces outward in a machine layout. Position data come from an integrated multiturn absolute encoder, so the controller can recover rotor angle after power returns. A sealed circular connector carries the electrical connections, and standard rotor balancing helps keep vibration low during repeated motion cycles.

The mounting pilot has a centering diameter of 110 mm, which helps align the motor with the machine plate during installation. Feedback is transmitted as Digital servo feedback (DSF), providing high-resolution position data through the motor connector. The 090 frame size supports compact machine layouts, and the output side uses a plain shaft with a shaft seal to retain lubricant and help keep contaminants out. There is no shaft extension on side B, which allows close coupling to gearboxes or belt pulleys and reduces overhung length at the drive end.
