MDD071A-N-040-N2T-095PL0
The MDD071A-N-040-N2T-095PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts electrical power into controlled mechanical rotation for indexing tables, pick-and-place heads, or small conveyor sections in automated lines. Its compact build allows integration close to the load, reducing coupling losses and improving servo stiffness in multi-axis assemblies. Because it is intended for closed-loop operation, the paired controller can regulate torque and speed continuously as load conditions change during each machine cycle.
Mechanical sizing is governed by the 071 frame code and the A length variant, while standard balancing keeps residual vibration low. The centering diameter measures 95 mm, establishing an accurate pilot fit on mounting flanges. Under continuous stall conditions, the rotor can sustain 2.2 Nm of torque, enabling stable holding or slow feed motion without excess heating. During running duty, it reaches a nominal speed of 4000 rpm, pairing well with high-speed indexing requirements. Motion data is returned through digital servo feedback (DSF), and position is captured by an integrated multi-turn absolute encoder that retains revolution count after power loss. This feedback arrangement gives the drive immediate position information and supports repeatable motion after brief supply interruptions.
Electrical terminations face the left side because the power and feedback cables plug into a sealed connector, simplifying cabinet layout and reducing exposed wiring at the motor body. The output shaft uses a keyway for positive coupling, and the motor has no second shaft end. A shaft seal is installed to limit oil egress, and the standard housing protects internal components without additional cooling devices. Because the unit ships without a blocking brake, position holding during power-off periods must come from external clamping or commanded drive torque.
