POWER SUPPLY CIRCUIT AND MOTOR DEVICE |
摘要 |
A power supply circuit has an input terminal for electrically connecting to an active wire of an AC power supply, an earth terminal for electrically connecting to a neutral or ground wire of the AC power supply, and a voltage decreasing unit. The voltage decreasing unit has an adjustable capacitor unit with adjustable capacitance for decreasing an AC voltage applied to the input terminal and an output terminal for outputting the decreased AC voltage. An electric motor is combined with the power supply circuit to form a motor device.
