Product Description:

The MDD090A-N-040-N2L-110PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotary actuation for axes that require accurate velocity and position regulation in automated machinery. By integrating with compatible drive modules, the unit converts commanded current into precise torque for duties such as packaging stations, assembly gantries, and material-handling lines.

Its nominal speed rating is 4000 rpm, allowing the drive to match mechanical gearing for rapid indexing while staying below the thermal limits of the A-length stator. At standstill, the motor delivers a continuous torque of 3.7 Nm, so it can hold loads without overheating during dwell periods. The centering shoulder measures 110 mm, providing a repeatable locating surface for flange mounting to gearboxes or frames. Power and feedback terminations face side A, simplifying cable runs in cabinets where the shaft projects forward, and all conductors are routed through a sealed connector to keep wiring changes quick.

Dynamic performance is supported by standard balancing, which minimizes residual vibration in the 090 frame size. Axis position is returned to the drive through digital servo feedback, permitting high-resolution commutation without external encoders. Because the unit is supplied without a blocking brake, stopping torque must be provided electrically or by an external clamp if vertical loads are present. A keyway shaft is provided for positive mechanical coupling, and the front bearing region is protected by a shaft seal to limit lubricant leakage. The housing and shaft end follow the standard design codes, and the motor length code A keeps the overall depth compact for shallow machine bays.
