Product Description:

The MDD065D-N-040-N2M-095GA1 is a synchronous motor from Bosch Rexroth Indramat's MDD Synchronous Motors series. Built for digital drive controllers, it supplies closed-loop rotary motion for indexing tables, pick-and-place heads, and other automated axes that require repeatable positioning. The design pairs a compact 65 mm frame with an internal blocking brake so the shaft can remain fixed during power interruptions or emergency stops.

Under stall conditions, the rotor continuously delivers 2.7 Nm of torque, giving drives steady force for creeping or tension-control tasks. When operated at its nominal velocity of 4000 rpm, the motor balances speed with thermal loading suited to high-cycle machines. The integrated brake applies 3.0 Nm of holding torque, which helps prevent back-driving on suspended loads. A centering shoulder diameter of 95 mm aligns the housing to gearboxes or adapter plates, while standard dynamic balancing helps limit residual vibration. Electrical leads exit on side A, and a fitted shaft seal helps block dust and spray from reaching the front bearing.

An integrated multi-turn absolute encoder records angular position across power cycles and sends that data to the controller through digital servo feedback (DSF) for precise commutation. Power and feedback conductors mate to a single industrial connector, which keeps cable routing compact when space around the motor is limited. The plain shaft configuration avoids keyways to help minimize play, and the shaft end is provided only on the working side to reduce overall length. Standard housing and cooling are suitable for cabinet-mounted installations, while motor length code D provides a balance between torque output and installation space. With 065 as its frame designation, the unit fits fixtures designed around smaller members of the MDD family without adapter rings.
