The first power-saving power switch inside the main switch is closed for conduction, and the second AC power switch inside the sub-switch is opened to be turned off, so that the second power-saving power switch inside the sub-switch is closed As a conduction, the current limiting AC motor is powered by the AC power source via the power saving controller of the current limiting AC motor power saving device, and the main brush can supply power to the NS electromagnet stator and the SN electromagnet inside the brush AC motor. The main coil rotor and the main coil rotor (power supply main coil) simultaneously drive the main coil rotor and the sub coil rotor to rotate, and the electromagnetic induction between the sub coil rotor and the NS electromagnet stator and the SN electromagnet stator can further generate electricity ( The secondary coil generates electricity), and the load operation (AC power-saving power supply motor) is driven in a power-saving manner, and does not affect the normal operation of the load, and the motor is utilized. In other words the concept of power, will be able to reach "limiting energy-saving AC motor can save power" power supply function of.
