Product Description:

The MDD090A-N-030-N2L-110PB2 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is intended for use with digital drive controllers in applications that require closed-loop velocity and position control. In automated machinery, the motor converts commanded current into mechanical rotation so that linear axes, spindles, or indexing tables can follow precise motion profiles. Its frame size 090 and length code A indicate a compact build suited for restricted installation spaces where accurate servo performance is still required.

Mechanically, the motor centers on a 110 mm pilot, allowing repeatable flange alignment with gearboxes and machine frames. The housing follows the standard configuration used across the range, so the mounting points match existing brackets without redrilling. All power and feedback conductors exit at the rear because the connection hardware is located on side B and terminated through a keyed industrial connector. Under rated excitation, it reaches a shaft speed of 3000 rpm, which supports direct coupling to moderate-inertia loads without excessive gearing. At standstill, it can supply a continuous torque of 3.7 Nm, which allows the axis to maintain load during contouring or dwell periods within its thermal operating range.

An electromagnetic brake provides 11.0 Nm of holding torque when power is removed, helping prevent unintended movement on vertical or suspended axes. Rotor position is returned to the drive through digital servo feedback (DSF), allowing the controller to correct deviations in real time and maintain stable motion control. A radial shaft seal protects the bearing cavity, and the single-ended shaft uses a keyway for secure torque transmission to the coupled load. The rotor uses standard balancing, which helps limit vibration across the speed range and supports smooth operation during continuous duty.
