Product Description:

The MDD065-N-040-N2L-095PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into rotary motion for automated positioning and speed-control tasks on packaging machines, handling axes, and similar equipment. The unit is built without a blocking brake, so any requirement for static holding torque must be provided by an external clamping mechanism or by the drive. This arrangement suits applications where stopping force is managed elsewhere in the machine system rather than inside the motor.

MDD size 065 uses a centering pilot of 95 mm to align the housing with machine frames and help maintain concentric rotation. Under rated excitation, the rotor can reach a nominal speed of 4000 rpm, allowing fast cycle times while remaining within the thermal capability of the winding set. A shaft diameter of 17 mm supports torque transfer to couplings or pulleys, and the external casing has an IP65 rating that helps keep dust and water jets away from the internal windings and resolver. The model’s maximum center-hole torque is limited to 1 Nm, which helps prevent thread damage during puller use and other service-related removal work.

Mounting is completed through the face flange, which provides a tapped center hole of M3-8 and accepts retention loads only up to the stated limit. The output key dimensions are 5 × 5 × 22 mm, allowing the shaft to mate with standard hub slots formed in accordance with DIN 6885. Power and feedback leads exit on Side B, which can help keep the connection area clear in compact machine layouts. Installation height may not exceed 1000 m so cooling performance and dielectric strength remain within the intended operating range. Velocity and position are returned to the drive through Digital Servo Feedback, allowing high-resolution control loops for responsive motion and stable regulation during operation.
