MDD065C-N-040-N2M-095PL0
The MDD065C-N-040-N2M-095PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It pairs with digital drive controllers to convert commanded current into precise rotary motion for positioning, conveying, and light machining tasks. A frame size 065 stator, length code C housing, and standard balancing let the rotor reach rated velocity while keeping vibration low across the duty cycle. Its synchronous design also supports repeatable positioning during start, stop, and reversal commands in automated axes that must follow changing speed profiles.
At the mechanical interface, the centering pilot measures 95 mm, providing a reference surface for concentric mounting to gearboxes or adapter plates. Power and feedback leads exit on the left side through a plug-in connector, which can simplify routing when the motor faces inward on a machine frame. During static holding, the electromagnetic design can maintain 2.1 Nm of continuous torque, so index tables can remain in position without auxiliary clamping devices. Once energized, the winding and iron geometry support a rated speed of 4000 rpm, which suits short-cycle applications. Rotor position is resolved by an integrated multi-turn absolute encoder, enabling the drive to recover angle information after power loss without external homing. This arrangement also helps maintain shaft alignment and limits coupling stress during operation.
Closed-loop control uses digital servo feedback (DSF) signals that travel alongside the power phases, allowing fast correction of phase currents commanded by the controller. A factory-fitted shaft seal blocks coolant splash and fine dust from entering the bearing region, which helps preserve grease life under high duty. Because the motor is supplied without blocking brake, it can decelerate freely and is suited to axes that rely on drive-based braking. The motor uses a keyed shaft to couple torque directly while preserving alignment. This output arrangement supports secure power transmission to pulleys, couplings, or gear inputs in compact machine layouts.
