It comes with the advanced Hall sensor design. Using the Hall sensor signals, the control system is able to execute the PWM commutation by switching the three-phase inverter. There are two PWM modes Sine-Wave Mode and Square-Wave Mode. The Square-Wave Mode includes PWM-PWM and PWM-ON approaches to improve the efficiency of the motor drive. Complete protection functions including over-voltage, over-current, over-temperature, and short-circuit protections prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
