Product Description:

The MDD112C-N-040-N2M-180PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Sized to the 112 frame and supplied in the length-code C housing, it is balanced to the standard grade for mounting on precision machinery. This model is intended for operation with digital drive controllers in automated equipment, where its electrical commutation and positional feedback allow closed-loop speed and torque control on production lines, packaging stations, and gantry axes.

At standstill, the motor can deliver a continuous torque of 28.0 Nm, enabling it to hold loads or start acceleration without overheating. When driven at its nominal speed of 4000 rpm, the rotor maintains synchronous motion with the stator field so that velocity commands from the drive translate directly to shaft speed. Accurate mechanical alignment during installation is aided by the centering shoulder diameter of 180 mm, which matches the machine flange. Position and velocity data are returned to the controller through digital servo feedback (DSF), and both power and signal conductors exit on the rear flank because the connection hardware is mounted on side B of the stator housing. This layout keeps the cable outlet at the rear of the motor and supports orderly cable routing inside the machine.

Additional functions are handled by the built-in integrated multiturn absolute encoder, which tracks shaft position over multiple revolutions without external batteries. Mating cables attach through a keyed connector that supports quick connection and secure alignment. The mechanical design ships without a blocking brake, so external holding methods must be used if the axis must stay fixed when power is removed. A contact-lip arrangement provides sealing, and the front end is equipped with a shaft seal to limit grease egress and dust ingress around the keyway shaft.
