With the development of the economy, electrical appliances are constantly being invented, and many household appliances are gradually being invented, such as refrigerators. No matter what the brand or price changes, people pay attention to the working efficiency of the motor. Motors are the power devices of automation equipment, pumps, and fans, and are also the main components of household appliances such as air conditioners, washing machines, and refrigerators. The electrical energy consumed by motors accounts for about 50% of the world's total electricity consumption, so improve the efficiency of motors. It is the point of energy saving. Types of motors include AC induction motors and brushed DC motors, but these motors all work on the same principle.

In recent years, electrical and electronic technology, which has become the backbone of household appliances, has been highly developed and widely used. The motor is the core driving component of the electromechanical energy conversion of household appliances [1], and is widely used in the field of household appliances. The performance index of the motor It directly affects the performance of the electrical appliance, and the service life of the motor also directly affects the service life of the electrical appliance.

Characteristics of existing home appliance motors

One, single-phase induction motor. Although new types of motors are emerging on the market, single-phase induction motors are still mostly used in current home appliances. Single-phase induction motors are simple in structure, energy-saving and easy to produce, with relatively low cost and relatively mature technology.

Second, the single-phase variable induction motor. In home appliance motors, variable-speed motors have certain applications, which can be seen in the application of washing machines, but at present, single-phase variable-speed induction motors are gradually being replaced by other motors.

Three, three-phase induction frequency modulation motor. Relatively speaking, the production process of three-phase induction frequency modulation motor is relatively mature, and the reliability of operation is relatively high.

Fourth, the permanent magnet synchronous water pump motor. The characteristic of this type of motor is that the pump and the motor are integrated, the rotor of the motor is a two-stage annular permanent magnet, there is no electronic controller, and it is started by the whole building, and the direction of rotation is difficult to determine.

As there are more and more types of household appliances, and some electrical appliances have increasing requirements for motors, there are still some problems with household motors due to economic development. Home appliance motor products are developing in the direction of high performance, permanent magnetization and mechatronics. Due to the wide application range of three-phase asynchronous motors, various failures will occur after long-term operation.

We take air conditioners as an example to analyze how to save energy. First of all, it is necessary to improve the maintenance structure of the room. For some rooms with poor door and window structure and relatively large gaps, some emergency measures can be taken, such as sealing the gap with tape and pasting a layer of transparent plastic film outside the glass window. When the air conditioner is cooling, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect will be better. Don't turn on and off frequently. This not only consumes electricity, but also can easily cause damage to the engine if the machine is switched on and off frequently. It is also necessary to keep the air outlet smooth. Do not pile up large pieces of furniture to block heat dissipation and increase insignificant power consumption. It should be noted that whether the air conditioner saves electricity or not depends on each The energy efficiency ratio of the air conditioner, the higher the energy efficiency ratio, the more energy saving.

Since the motor is an important part of household appliances, it is necessary to ensure the service life of the motor, so as to ensure the service life of the household appliance. Of course, we should also do a good job of energy-saving measures for the motor system, such as selecting reasonable equipment selection, speed regulation of the motor and using the motor. Doing a good job in the energy-saving work of the motor system can also further promote the technological progress of my country's motor industry and related industries. Promote the development of our country's economy.
