Product Description:

The MDD090A-N-030-N2L-110GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supplies controlled rotary motion to machine axes that require repetitive positioning and stable speed regulation. The motor uses integrated digital servo feedback, allowing the drive to monitor rotor position continuously and correct for changes in speed or load during operation. Its standard housing and compact frame make it suitable for automated equipment where accurate motion and predictable installation are both important.

The motor provides a continuous standstill torque of 3.7 Nm, allowing it to hold a load at zero speed within its thermal capacity. Its nominal speed is 3000 rpm, which supports high-speed operation in indexing, transfer, and feed applications. A centering diameter of 110 mm helps align the motor accurately with a gearbox or mounting flange. Power and feedback lines exit on the right side through a molded connector, which helps reduce cable strain in compact installations and keeps the connection secure during vibration. The motor is designed for stable closed-loop motion in equipment that depends on repeatable starts, stops, and speed changes.

The motor has a frame size of 090, and the A length indicates the shortest housing in this frame. It uses a plain shaft and is supplied with a shaft seal, which helps limit lubricant escape and reduces the entry of contaminants near the bearing area. The unit is supplied without a blocking brake, so any holding force during power-off conditions must come from the drive or from an external mechanical device. The shaft is provided only on side A, and the standard housing layout supports straightforward mechanical integration where shallow installation depth is required.
