Product Description:

The MDD071A-N-040-N2S-095PA2 is a synchronous motor in the MDD Synchronous Motors series for use with digital drive controllers. It is built as a motor for digital drive controllers, using motor size 071 with the compact motor length code A in a standard enclosure with standard rotor balancing. This arrangement suits tightly spaced machine axes that need accurate rotary motion and stable response during repeated positioning. The motor is intended for compact automation layouts where direct integration with the drive helps maintain precise control of speed and position.

The centering flange has a diameter of 95 mm, which helps align the motor accurately to a gearbox or machine plate. Power and feedback leads exit on Side A, and the connections are made through a compact connector rather than a pigtail. At standstill, the rotor can deliver a continuous torque of 2.2 Nm, which supports steady holding force for smaller positioning duties within normal thermal limits. During operation, the motor reaches a nominal speed of 4000 rpm, making it suitable for direct coupling to light loads while keeping speed control smooth across the usable range.

A built-in holding brake with blocking action supplies 6.5 Nm of static torque, so the axis can remain in place when power is removed. Position data is provided to the controller through digital servo feedback (DSF), which allows closed-loop operation without an external encoder assembly. The output shaft is a single-shaft design with a keyway for positive mechanical coupling, and it includes a shaft seal to help limit lubricant entry and contamination at the shaft interface. Because there is no shaft extension on side B, the motor can fit into installations where rear clearance is limited and cable routing must remain compact.
