Product Description:
The MDD090C-N-030-N2M-110PA1 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated electrical output into rotary motion for industrial axes that require precise speed and torque control. The motor is suited for machine tools, packaging systems, and handling equipment where closed-loop motion must remain stable during repeated operating cycles. It supports consistent rotary output during acceleration, deceleration, and dwell periods, and its housing follows the frame and mounting pattern used across this motor family.
The motor delivers a continuous standstill torque of 10.4 Nm, allowing the axis to hold load at zero speed without excessive thermal stress. Rated speed reaches 3000 rpm, giving the connected drive a practical operating range for direct-drive or geared applications. A centering diameter of 110 mm provides the pilot fit for flange mounting and helps align the motor accurately with the machine frame. The integrated blocking brake supplies 6.5 Nm of holding torque to secure vertical loads when power is removed, and the frame code of 090 places the unit in the corresponding mechanical envelope for this motor size. The brake is intended for holding duty when the axis is stopped.
Electrical and feedback connections are arranged on Side A, so the cables leave the motor in one direction for a cleaner routing path. The motor uses a Connector style termination, which allows direct connection at the housing without fixed flying leads extending from the case. Torque is transmitted through a keyway shaft, giving couplings a positive mechanical interface that helps resist slip during reversing motion. Position information is returned through digital servo feedback (DSF), enabling the controller to manage velocity and position loops with encoder data from the integrated feedback system. Because the power and feedback interfaces are grouped on one side, nearby machine structures can remain clear of unnecessary cable crossover.
