Product Description:

The MDD071C-N-040-N2S-095GB2 is a brushless synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts controlled electrical power into precise rotary motion for positioning, pacing, and contouring tasks on automated machinery. Its electromechanical layout allows direct mounting to transmission elements, while the standard housing and balancing support use in modular motion systems that need stable running behavior. This arrangement is well suited to automated axes that require accurate speed regulation during repeated starts, stops, and contouring moves.

The motor delivers a continuous standstill torque of 6.6 Nm, and it reaches a nominal speed of 4000 rpm, giving the drive a wide constant-power range for rapid indexing cycles and responsive speed changes. A centering diameter of 95 mm provides accurate concentric seating against the machine flange, and the shaft is dynamically balanced to a standard grade to reduce vibration at higher speeds. Electrical power and feedback conductors exit on side B through a keyed connector, which helps keep cable routing orderly around the motor body. Position information is returned through digital servo feedback, allowing the controller to close high-resolution velocity and position loops during dynamic motion profiles.

For holding tasks on vertical or indexing axes, the motor includes a blocking brake rated at 6.5 Nm of static torque, and it is released automatically when drive current is applied. The mechanical interface uses size code 071 and length code C, which gives a compact envelope that suits mid-range loads and helps manage thermal rise in continuous operation. The motor has a plain shaft with a shaft seal, which helps limit dust ingress and lubricant escape during service. The shaft end is present only on the drive side, so there is no extension on the opposite face.
