MDD071A-N-030-N2S-095GL2
The MDD071A-N-030-N2S-095GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is designed for digital drive controllers, so it supplies closed-loop rotary motion to axes that rely on electronic position and velocity control in automated machinery and material-handling systems. In typical servo operation, the matched drive adjusts motor current continuously so commanded motion can be maintained as load conditions change. Its synchronous design supports repeatable acceleration, steady running speed, and responsive positioning over repeated duty cycles. Size code 071 and length code A set the overall stator dimensions, and the standard housing suits general-purpose installation without optional cooling fins.
The motor’s centering diameter measures 95 mm, providing the reference surface that aligns the frame to a gearbox or mounting flange. A continuous torque of 2.2 Nm can be delivered at standstill, and the motor reaches 3000 rpm under rated operating conditions. That speed range fits many standard servo applications without requiring a special gearing arrangement. Position and speed data are returned through digital servo feedback (DSF), allowing the connected drive to close the control loop without an external encoder. Because the feedback device is integrated into the motor, signal routing stays compact and the controller can monitor rotor movement directly during acceleration and positioning. Power and feedback leads enter from the left side through a connector, which simplifies cable attachment and routing.
A blocking brake is included and applies 6.5 Nm of holding torque to secure the rotor when the system is powered down. This feature is useful when an axis must remain in place at standstill instead of drifting under a suspended or offset load. The load is transferred through a plain shaft that conforms to ISO fit tolerances and uses a shaft seal to limit lubricant migration and dust ingress. The rotor uses standard balancing, which keeps residual vibration within normal limits for belt-driven or coupling-driven assemblies. The shaft end is provided only on side A, leaving the non-drive side clear for the brake and integrated feedback components.
