Product Description:

The MDD093C-N-040-N2M-110GB0 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is designed for use with digital drive controllers, where commanded current is converted into controlled torque and speed for automated motion. This operating role suits positioning tasks that require stable response during repeated starts, stops, and speed changes. The unit occupies the 093 frame, uses a standard housing, and is factory balanced to a standard grade, so it can be mounted on typical flange arrangements without added vibration isolation.

Its nominal rotor velocity reaches 4000 rpm, providing high-speed motion for pick-and-place or spindle axes when drive frequency matches the motor’s electromagnetic pole pair count. A centering shoulder of 110 mm aligns the stator concentrically to machine plates, which helps keep coupling runout low. All power and feedback conductors exit on side B, and the sealed connector interface protects the contacts while keeping cable routing orderly at the rear of the motor. The output shaft is a plain shaft with a keyless cylindrical surface, and the front bearing cavity is guarded by a shaft seal that restricts oil or coolant ingress. The shaft protrudes only on the drive side because the model uses the standard shaft-end arrangement without a side B extension, which helps limit overall motor length.

The motor body follows motor length code C, giving an active stack that balances continuous torque with compact mass. Position data is supplied by an integrated multi-turn absolute encoder, and the drive processes this signal through digital servo feedback to maintain closed-loop accuracy during changes in load or speed. Because the feedback system tracks position over multiple revolutions, the controller can retain shaft position information through normal operating cycles. For applications that use external holding devices, the unit is supplied without a blocking brake, so no residual holding torque is generated when power is removed.
