Product Description:

The MDD093C-N-020-N2M-130PL0 is a permanent-magnet synchronous motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. Designed as a drive element for digital controllers, it converts commanded current into proportional torque for positioning, conveying, and forming equipment. Its size 093 frame and length code C place it in the mid-range of the series, giving a compact option when closed-loop rotary motion must respond quickly to electronic feedback. This motor type is commonly used where a servo drive manages speed and position through continuous feedback.

Its centering flange is machined to 130 mm, providing a reference surface that aligns the stator housing concentrically with gearboxes or direct-drive mounts. This arrangement helps keep the motor and the driven load properly aligned during installation. The rotor can sustain a nominal shaft speed of 2000 rpm, so the motor suits moderate-speed axes without excessive inverter frequency. All power and feedback leads exit on the left side of the housing, which can simplify routing when motors are installed in mirrored pairs. A keyed circular connector carries both three-phase power and encoder signals, and the built-in integrated multi-turn absolute encoder returns shaft position over multiple revolutions without requiring homing after power loss.

For control resolution, the motor uses digital servo feedback (DSF), allowing the drive to compare commanded and actual positions in real time and correct deviation before it affects cycle accuracy. Because the rotor is supplied without a blocking brake, holding torque must come from the drive or from external mechanical locks when the axis is idle. The output shaft has a keyway so couplings can transmit torque without slip, and it uses a shaft seal to keep lubricant in and airborne particles out. Standard dynamic balancing limits vibration at rated speed, and the housing maintains IP65 protection against dust and low-pressure water.
