Product Description:

The MDD065C-N-040-N2L-095PA1 is a synchronous motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as the electromechanical actuator for rotary axes and transfer mechanisms in automated production lines, translating drive commands into regulated motion for positioning and process control tasks. The motor is intended for use with digital drive controllers, and it has a single-ended shaft with no extension on side B. That arrangement suits compact axis layouts where rear clearance is limited. It can be installed where machine frames leave little room behind the motor body.

This model reaches a top regulated speed of 4000 rpm, allowing fast cycle times when paired with a matching inverter. At standstill, it can deliver 2.1 Nm of continuous torque, so it can hold light loads during steady operation without excessive thermal stress. A centering diameter of 95 mm helps align the motor with gearboxes or flange plates. Power and feedback conductors exit on Side A through a sealed circular connector, which helps keep cable routing consistent in compact enclosures. The motor uses digital servo feedback for high-resolution closed-loop control, and the 065 frame size corresponds to its stator diameter. A standard housing protects the windings without added cooling ducts, and factory balancing limits vibration during high-speed operation.

A blocking brake is integrated and provides up to 3.0 Nm of holding torque to secure vertical or suspended loads when power is removed. Mechanical coupling is handled by a keyway shaft, and a shaft seal helps prevent lubricant migration into the bearing chamber. The rotor-stator stack uses length code C, which provides more active iron than shorter lengths in the same frame size. That longer stack suits applications that need more rotor mass than shorter motor lengths provide.
