Abstract
The utility model discloses a rotation speed regulator for a single-phase ac motor. More specifically, a printing circuit plate is arranged in a case body, and the printing circuit plate has the special operation principle that the single-phase voltage of 220 volts is commuted via semiwaves and descended via an electric resistor R4 to supply power for a voltage stabilizing tube D3 and for the usage of an integrated circuit. The smooth voltage can be transferred by the voltage stabilizing tube via the parallel connection of the voltage stabilizing tube D3 and a capacitor C1, and the adjustable voltage supplied by a potentiometer RK and input by the integrated circuit via foot 12 can be adjusted to control double-direction controllable silicon V, so the purpose of rotation speed control can be achieved via the transformation of a turnon angle.
