Abstract
PURPOSE: To enhance the efficiently of a shading motor during its operation by providing the same number of turns of the exciting coil as that of the shading coil of the motor and shorting the shading coil at starting time.
CONSTITUTION: The number of turns of the shading coil 10 of a shading motor having a rotor core 2 and an exciting coil 4 is not provided with one turn as the conventional one, but provided with substantially the same as that of the coil 4. In addition, an external impedance 30 is connected through a switch 20 between the terminals of the coil 10. When the switch 20 is closed at starting of the motor, induced current occurs at the coil 10 to produce moving magnetic field in the gap to thereby generate a starting torque thereat. After starting the motor, the switch 20 is opened.
