Product Description:

The MDD090B-N-020-N2L-110GB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated three-phase power into torque and speed that can be coordinated with PLC motion sequences. The motor’s internal sensors relay position data back to the drive so automated packaging lines, pick-and-place modules, and other axes can hold commanded positions, accelerate smoothly, and repeat cycles during continuous industrial service.

This model delivers a continuous stall torque of 7.2 Nm, giving the drive enough margin to support static holding forces and slow-speed feed moves without overheating. When power is removed, the integrated blocking brake applies a restraining force of 6.5 Nm, which helps prevent load drift on vertical or cantilevered mechanisms. Under normal operation, the rotor can reach a nominal speed of 2000 rpm, which supports practical travel rates and suitable gear selection for connected machinery. Mechanical alignment to gearboxes or couplings is simplified by a centering diameter of 110 mm, and motion feedback is provided through digital servo feedback (DSF), allowing high-resolution position loops inside the drive.

Power and feedback connectors are arranged on side B, which can simplify cable routing in narrow cabinets or compact machine frames. The rotor is balanced to standard balancing, helping vibration remain within normal limits at rated speed. A sealed, plain shaft transfers torque while a shaft seal helps block lubricant migration and airborne contaminants. The housing uses the 090 frame code with B length, giving the motor a compact format that still accommodates the brake and feedback modules without exceeding typical servo motor size expectations.
