Product Description:

The MDD090C-N-040-N2L-130PB0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts commanded current into rotary motion that can be tightly coordinated with axis drives in machine tools, printing lines, and material-handling stations. Pairing it with a Rexroth drive enables closed-loop velocity and position control suitable for repetitive industrial cycles where repeatable torque and speed accuracy are required.

The unit supplies a continuous standstill torque of 10.4 Nm, giving machinery enough holding force to resist load when the shaft is energized but motionless. Under rated electrical frequency, it can reach a nominal speed of 4000 rpm, allowing high spindle or feeder rates without mechanical gear multiplication. Rotor position is reported through Digital servo feedback (DSF), so the controller receives high-resolution data for commutation and diagnostics. Precise mechanical alignment is supported by a centering diameter of 130 mm, which matches standard flange seats in Rexroth mounting kits. The output shaft is machined with a keyway, which locks pulleys or couplings to the shaft and helps prevent slip under cyclic torque reversals.

The connection point is on the motor’s Side B, simplifying cable routing when the housing is mounted against a machine frame. A single multipole connector carries both power and feedback signals in shielded conductors to reduce enclosure penetrations. The motor uses length code C, which corresponds to the stator stack depth needed to achieve the stated torque without increasing the 090 frame cross-section. The design is supplied without a blocking brake, meaning any required holding during power loss must be provided by the drive or external mechanical restraints. A shaft seal protects internal bearings from coolant splash or airborne oil, and the standard balanced rotor minimizes vibration at the full speed rating.
