Product Description:

MDD090C-N-040-N2L-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It works with digital drive controllers to convert commanded current into controlled shaft rotation for automated machine axes. This makes the motor suitable for packaging, handling, and other general motion tasks that require repeatable speed and position control.

In operation, the motor reaches a nominal speed of 4000 rpm, allowing fast cycle times when paired with the specified digital drive. At standstill, it can deliver 10.4 Nm of continuous torque, so holding force is maintained without temperature overrun. Rotor alignment to mounting hardware is aided by the centering diameter of 110 mm, while standard balancing helps limit vibration during operation. Position data returned through digital servo feedback (DSF) enables the controller to correct velocity deviation in real time. Mechanical power leaves the shaft through a keyway, which simplifies coupling to pulleys or gears in compact installations.

The integrated blocking brake supplies 11.0 Nm of static torque, allowing vertical or oscillating loads to remain fixed when power is removed. Electrical power, feedback, and brake leads route toward the rear on Side B, and termination is made with a keyed connector that provides a secure mating interface without disturbing sealing surfaces. A shaft seal around the output journal helps prevent coolant or dust ingress and retains grease inside the standard shaft-end bearing arrangement. Frame size 090 and length code C indicate the stator stack depth and mounting pitch for this motor. The standard housing dissipates heat without auxiliary cooling. The shaft end is supplied in the usual form and does not extend from the rear of the motor, leaving clearance for encoder cabling and brake hardware.
