Product Description:

The MDD090A-N-040-N2M-130PB2 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where rapid torque response and position repeatability are required in industrial automation cells, pick-and-place modules, packaging axes, and other coordinated motion systems. A blocking brake is integrated to secure loads during power-off periods, and rotor position feedback supports closed-loop regulation throughout the operating cycle. This arrangement supports precise positioning and repeatable speed control during frequent start-stop motion.

The motor can deliver a continuous standstill torque of 3.7 Nm, allowing it to hold static loads without overheating under rated current. During motion, it reaches a nominal speed of 4000 rpm, matching drive systems that issue high-frequency velocity commands. The blocking brake supplies up to 11.0 Nm of counter-torque, which helps prevent back-driving on vertical axes when the controller is disabled. Mechanical alignment to the driven assembly is guided by a centering diameter of 130 mm. Electrical position data is transmitted through digital servo feedback (DSF), so the controller can synthesize precise torque vectors without additional sensors.

Standard rotor balancing minimizes vibration, and the cast housing has a standard finish suitable for general machinery enclosures. Power and feedback leads exit through a connector on side B, simplifying cabinet wiring layouts. The unit has motor size 090 and length code A, which shortens installation depth for compact axes. An integrated multi-turn absolute encoder tracks several mechanical revolutions, eliminating the need for homing after shutdown. A shaft seal is fitted to impede lubricant ingress, and the output shaft is ground with a keyway so coupling torque can be transferred through keyed hubs. The shaft end is supplied only on the drive side.
