The electric spark machine USES ac motor or dc motor!
The external power supply is ac, but the electric spark machining is dc, and there is a rectifier in the interior, and the dc resistance communication. By a half wave of positive and a negative half wave voltage is composed of alternating current (ac), and there is only one direction (positive or negative) of a certain voltage is dc pulse width; By the pulse of dc power induction, the induction is still a dc pulse, and if the ac is ac, a cycle will have a minimum of two ignition cycles, no drops, please take it.
The upstairs talk is too absolute. The control mode of the spark machine is relatively simple, and the power of the motor is smaller, under 100W. Most electric spark machine is made of dc servo motor and electronic ruler.
I remember that it was the ac motor. Please take it. Thank you.
