High performance built-in AC spindle motor for Fanuc CNC system. It adopts sinusoidal vector control winding structure, the built-in position sensor feeds back rotor speed and phase signal to spindle amplifier. It realizes wide constant power speed regulation range, supports rigid tapping, C-axis positioning and heavy cutting. Integrated temperature detection circuit provides overheat alarm protection.

Certification: CE

Stator winding assembly, rotor, built-in speed sensor, temperature detection thermistor, power and signal connector. Common faults: winding insulation damage, sensor signal loss, zero drift, over-temperature alarm and bearing wear.
