Product Description:

The MDD093C-N-040-N2M-110PB2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for positioning and speed-regulated axes in automated machinery. In a servo system, the motor works with the drive to maintain commanded position, speed, and torque as machine loads change during operation. This makes it suitable for equipment that requires repeatable motion and stable closed-loop performance.

The unit has a rated speed of 4000 rpm, which is its continuous shaft speed under nominal voltage and load. A blocking brake rated at 22 Nm holds the shaft when power is removed, which helps keep vertical or suspended loads stationary. This arrangement is useful on axes where unwanted movement after shutdown must be avoided. Accurate mechanical alignment is supported by a centering diameter of 110 mm. The output shaft uses a keyway so torque can be transferred without slip. Standard dynamic balancing helps limit vibration, and the sealed housing includes a shaft seal to reduce contaminant entry near the bearing area.

Closed-loop control is supported by digital servo feedback (DSF) and an integrated multi-turn absolute encoder, allowing the controller to read rotor position after power cycling. Absolute position data is therefore available immediately at startup on compatible systems. The power and signal plugs face side B, which can simplify routing when cable trays are placed on that side of the machine. A round industrial connector carries the motor power and feedback lines through a single connection point. The motor uses frame size 093 with length code C, giving it a longer housing than shorter versions in the same frame. The shaft is supplied only on the drive side, so there is no side-B shaft end.
