Abstract

The present invention relates to an AC motor used wirelessly and charged with DC; and especially refers to an AC motor that can be charged with AC and store electricity in the CD battery, thereby upgrade the efficiency of motors. When the present invention is incorporated into the electric appliances, such as vacuum cleaners and mowers, users can move their electric appliances around. No power cord is needed any more and, therefore, the present invention is a practical design for electric appliance users.

Claims

1. An AC motor used wirelessly and charged with DC is provided with a power-inputting, controller, AC motor, high-frequency transformation circuit, high-frequency control circuit, AC-DC switching circuit, stabilization circuit, automatic control circuit, battery, DC-AC power converter, and power converter. Of which:

the power-inputting means the power cord that connects to the receptacle for power supply;

the controller means a switch that allows users to choose either power-inputting or CD-AC power converter as the source of power for AC motor;

AC motor means a conventional motor;

high-frequency transformation circuit and high-frequency control circuit control and adjust the voltage to the required level by high-frequency method;

AC-DC switch circuit converts the AC transmitted by power-inputting into DC;

stabilization circuit stabilizes the DC that has been adjusted;

Automatic control circuit stores the DC in the battery;

and DC-AC power converter adjusts the DC stored in the battery into AC, thereby allows users to switch the controller in order to supply power to the AC motor.

2. An AC motor used wirelessly and charged with DC as stated in claim 1, the present invention is designed for the electric appliances such as vacuum cleaners and mowers.
