Product Description:

The MDD090B-N-040-N2L-110PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotation for packaging, printing, and material-handling axes. The unit occupies the 090 frame size and comes in a standard housing that supports direct cabinet or machine-bed mounting. Its single output shaft, supplied without a rear extension, lets the integrated feedback device and blocking brake sit on the non-drive side without increasing overall length.

The motor’s nominal speed is 4000 rpm, meaning the rotor reaches that speed when operated at rated voltage and load. At standstill, it can supply a continuous torque of 7.2 Nm, which is suitable for accurate indexing or holding loads without overheating. An integrated blocking brake produces 11.0 Nm of static torque to lock the shaft when power is removed. Position and velocity data are returned through digital servo feedback (DSF), enabling the drive controller to issue finely resolved corrections. Accurate mechanical alignment during installation is supported by a 110 mm centering diameter that mates with standard pilot seats on gearbox flanges and coupling plates.

Dynamic behavior is improved by standard balancing, which helps reduce vibration across the speed range and supports smoother motion on precision axes. Power and feedback leads exit on Side A, and termination is made through a bayonet connector that permits quick disconnection during service. The single output journal follows a keyway profile for secure torque transfer, while the opposite end remains closed in line with the standard shaft-end option. The motor is built with a shaft seal to help prevent oil escape and block the ingress of dust or cutting fluid. The B body length gives the motor a medium axial profile that aids placement in tight cabinets and machine layouts.
