Product Description:

The MDD065D-N-040-N2L-095PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies closed-loop torque and speed in industrial automation cells that require compact rotary axes. The housing and rotor use the standard balancing grade, allowing direct coupling to precision gearboxes while maintaining low vibration during high-speed operation. This arrangement supports repeatable motion in indexing, feed, and positioning tasks where stable servo response is required.

The motor develops a continuous standstill torque of 2.7 Nm, giving stable force for holding or slow-moving duties without overheating. During motion, the rotor can reach a nominal speed of 4000 rpm, matching drive controllers that output high-frequency current. A centering diameter of 95 mm aligns the stator to the machine frame, and power plus feedback conductors exit on Side B through a low-profile connector. Position data is returned through integrated digital servo feedback, enabling the controller to correct position errors within each cycle. Length code D indicates an extended magnetic stack for higher torque density, and the standard housing finish protects the laminations in typical cabinet environments. This combination supports accurate speed regulation and smooth response when load conditions change during operation.

A shaft machined with a keyway transmits torque without relying on adhesive hubs, and a factory-installed shaft seal helps keep lubricants inside the gearbox while limiting contaminant entry. The motor has size code 065, which corresponds to a frame envelope suited to small to medium Indramat inverters. Mechanical energy can back-drive the rotor freely because the unit is supplied without a blocking brake, so applications that need static holding must use external clamps or drive-applied torque. The shaft end remains standard without an opposite-side extension, which helps simplify mounting in tight spaces and reduces added bearing load from extra mechanical connections.
