Abstract

A performance enhanced power economizer is used to directly save power from a main power source of an overall power consumption system and enables all machines in the whole power consumption system to reach the power-saving effects during operation. The present invention mainly uses a non-phase-controlled special winding to absorb the noise waves and harmonic waves in the power, which are caused by overload in order to eliminate the waste caused by noises and increase the power factor of the power use system. A special winding, together with an electromagnetic balance principle, is used to balance the phase of a three-phase power and voltage in order to ensure a smooth operation of an electric machine without deviation and improve the machine efficiency, while reducing the waste.

In the clutter, the harmonics are absorbed to increase the power factor, and the parental balance is changed to reduce the magnetic moment imbalance, improve the mechanical efficiency of the motor, and improve the power supply quality to save electricity. In the afternoon [prior art], the way to improve the power quality is to increase the power factor by means of capacitors and electronically controlled return buds to control the capacitor axis. But its control is complicated. There are many components in the circuit, and the quality control of each component is not easy and there are problems. Therefore, maintenance and maintenance are often required, which is not the ideal way. U.S. Patent No. 5,592,062 is a power factor control loop for a single induction motor in which four control groups are provided by a power supply unit 1 , a power supply adjustment unit (1), a receiving unit 12, and a microprocessor H 13 Matching is very complicated. Its control loop is as shown in the figure. Wherein, the power is generated by the capacitor diode 1 in the power supply circuit 1 through the capacitor 1〇2, the resistor 1〇3, and generates a DC 5 volt DC voltage, which is matched by the resistor 14 and enters the micro-processing s13iMCLR contact to provide “starting”. The power group 111 of the power supply adjusting unit 11 is located between the alternating current and the transistor 112, and the semiconductor diode 113 is connected to the transistor Π2 and outputs a DC voltage matched to the power supply circuit 1 to be processed. The micro-processing 13 output is used to control the receiving unit 12 to start the motor. Through the interaction of the four modules 10, 11, 12, 13, the input power of the motor is as close as possible to the output power, that is, the power factor of the motor is raised as much as possible. In order to achieve the purpose of electric power, in this device, as long as any one of the electronic components has a problem or is damaged, the device is ineffective and its reliability is very poor. Moreover, such a complicated device can only handle a single device. The power saving problem of small motors is really uneconomical.
