SANYO 1100W vacuum cleaner motor drive circuit

Shown is the motor drive circuit of the S AN YO IlOOW vacuum cleaner . As can be seen from the figure, the AC 220 V power supply supplies power to the vacuum cleaner circuit through the power switch S. The AC power supply supplies current to the drive motor through the bidirectional thyristor. By controlling the conduction period of the bidirectional thyristor vs, the energy provided to the drive motor can be controlled, thereby achieving control. The purpose of driving motor speed. The orientation thyristor T2 and the Ti electrode can be connected in two directions, so that AC signals can be passed. The condition for the bidirectional thyristor to conduct is that when there is voltage between the T1 and Tz poles, there is a pulse signal at the trigger pole G.
