MDD065B-N-040-N2M-095GR0
The MDD065B-N-040-N2M-095GR0 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts commanded current into controlled rotation that drives automated axes, pick-and-place heads, and packaging spindles on industrial production lines. By acting as the final electromechanical element in these systems, it carries out motion profiles generated by higher-level PLCs with repeatable speed and position.
A nominal velocity of 4000 rpm is the continuous operating speed ceiling, while a continuous standstill torque of 1.5 Nm lets the shaft hold loads during dwell periods without overheating. Accurate face mounting is aided by a 95 mm centering diameter, and the rotor is dynamically balanced to the standard grade to help limit vibration at that speed. Electrical and feedback leads exit on the right, and a compact power-and-signal connector simplifies cabinet wiring. Position information is returned through Digital servo feedback (DSF), allowing tight closed-loop regulation during rapid acceleration. The unit uses a standard housing that follows the 065 frame designation, so it can mount directly to gearboxes or mechanical subassemblies without adapters.
An integrated multi-turn absolute encoder retains position across power outages, which eliminates homing cycles at restart. The transmission element is a plain shaft, and a shaft seal blocks lubricant escape and contaminant entry at the housing interface. Motor length code B keeps the frame compact, and the model is supplied without a blocking brake, so any required static holding force must be provided by external clamps or by drive-controlled torque. The shaft end is standard on side A only, which avoids additional overhang mass on the non-drive side.
