Product Description:

Bosch Rexroth Indramat produces the MDD065C-N-040-N2M-095PB0 as part of the MDD Synchronous Motors series. The unit is a motor for digital drive controllers that supplies torque directly to machine axes in automated assembly lines, packaging equipment, and handling stations. Its compact 065 frame size is combined with a C length code to fit restricted installation spaces while still providing the output expected from servo stages that rely on high-speed closed-loop control. This layout suits machinery that needs precise starts, stops, and repeatable positioning during continuous production. It is suitable for axes that must cycle quickly while maintaining stable motion under changing process loads.

The motor delivers a continuous standstill torque of 2.1 Nm, allowing stable holding force when motion is paused without exceeding temperature limits. During operation, the rotor can reach a nominal speed of 4000 rpm, so the drive can execute rapid positioning sequences. Accurate velocity and position signals are returned through digital servo feedback that works with the drive control loop, while an integrated multi-turn absolute encoder supplies absolute position over multiple revolutions for startup without homing. Mechanical centering is simplified by a 95 mm centering diameter, and the rotor-shaft assembly is balanced to the standard grade to reduce vibration during high-speed operation. Power and feedback conductors terminate on a molded connector, which keeps the interface compact near the motor body.

Cables exit on Side B, which fits layouts where service access is available from the non-drive end. The output shaft uses a keyway to transmit torque to pulleys or couplings, and it includes a shaft seal to help limit lubricant migration into the stator air gap. For installations that need passive load holding, external brakes must be provided because the motor is supplied without a blocking brake, and the housing uses a standard enclosure form that protects the stator laminations from contaminants. The motor has a single shaft end, leaving the opposite side clear for encoder components.
