Product Description:
The MDD090B-N-030-N2M-110PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary actuator that converts drive current into controlled mechanical motion in automated lines, transfer systems, packaging stations, and precision handling equipment that use digital drive controllers. The unit has frame size 090, length code B, and a standard housing with standard rotor balancing, so it can be installed in standard machine layouts without additional counterweights or special mounting provisions.
This motor has a centering diameter of 110 mm, allowing precise alignment in flange mounts, and it delivers 7.2 Nm of continuous standstill torque for slow positioning cycles and holding duty at zero speed during indexing or dwell periods. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, providing a consistent speed reference for drive controllers that issue velocity commands during normal operation. Power and feedback conductors exit on side A through a compact connector, which helps keep cable routing orderly in cabinets and machine frames where installation space is limited. The shaft uses a standard single-ended keyway arrangement that mates directly with couplings or pulleys, and the built-in shaft seal helps prevent lubricant from entering the motor interior.
The integrated blocking brake supplies 6.5 Nm of static torque to secure vertical axes when power is removed or when the application requires holding force at standstill. Position information is supplied by an integrated multi-turn absolute encoder, and its multi-turn capability keeps position data available across multiple revolutions after shutdown instead of requiring a homing move at restart. For velocity and torque loops, the drive receives feedback through digital servo feedback (DSF), which supports high-resolution signal transmission over the hybrid cable set used by the motor. A standard shaft end on the drive side and a sealed rear cover help protect internal windings and magnetic components from dust and external contamination during regular operation.
