Integrates the advantages of AC servo and open-loop stepper technologies, overcoming traditional stepper motor limitations such as stalling, high power consumption, poor acceleration/deceleration dynamics, and high-speed instability. Expands stepper system applications while avoiding servo system challenges including complex parameter tuning, vibration at standstill, and high system costs, thereby significantly enhancing overall stepper system performance.
