Abstract
The utility model discloses an electric saver of an industrial sewing machine. The electric saver comprises a current transformer, a signal rectification amplifying circuit, a conduction angle regulating circuit and a bidirectional thyristor. The input end of the current transformer is connected with a power supply wire, the output end is connected with the bidirectional thyristor by the signal rectification amplifying circuit and the conduction angle regulating circuit, and the output end of the bidirectional thyristor is used for connecting a sewing machine motor driven by the directional thyristor. The electric saver is used and installed on the sewing machine; when the load of an electric motor is light, the current, the regulating of a conduction angle, the output voltage and the motor current are all reduced. If the load is increased, the current transformer induces that DC voltage signal of a signal rectifying circuit is also increased; therefore, the conduction angle regulating circuit is deepened, the conduction angle of the bidirectional thyristor is increased, the voltage output to the motor becomes high, the heavy-load voltage of the motor becomes high, the light-load or idle-load voltage becomes low, the rotating speed of the motor is remained unchanged, the current is reduced, and the purpose of electric saving is achieved.
