[ technical field ] A method for producing a semiconductor device

The utility model relates to a wireless remote control intelligent integrated motor.

[ background of the utility model ]

The single-phase alternating current asynchronous motor is widely applied to small household appliances, and the single-phase alternating current motor serves as a power source in various household appliances such as an exhaust fan, a bath heater, an air purifier and a cooling fan. Because the efficiency of the small single-phase asynchronous alternating current motor used in the household appliance is extremely low, generally between 10 and 25 percent, and various defects of high noise, difficult speed regulation and the like exist, in recent years, a plurality of products are changed into high-efficiency variable frequency motors to replace the traditional single-phase alternating current motor. The high-efficiency variable frequency motor can easily achieve the efficiency of more than 65%, greatly improves the energy utilization rate, accords with the energy-saving and emission-reducing directions of social development and national requirements, can perform various intelligent controls, and is the future direction of the motor development in the household appliance market.

The high-efficiency variable frequency motors in the market at present have two types, namely a traditional high-power alternating current variable frequency motor applied to 380V industrial electricity and a low-power direct current variable frequency motor.

In addition, the size and the mounting hole position of the direct current variable frequency motor are different from those of the traditional single-phase alternating current motor, and the power supply mode needs to be changed, so that the direct current variable frequency motor cannot be used for directly replacing the original alternating current motor on a product, a new structural design must be carried out on the direct current variable frequency motor, and structural spaces such as a power supply, a driver, a control panel and the like are arranged. Therefore, the application of the direct current variable frequency motor to household appliances is limited, and the cost of replacing the traditional alternating current motor by the direct current variable frequency motor is greatly increased.

The existing alternating-current variable-frequency motors are three-phase alternating-current motors used for inputting industrial electric power AC380V, cannot be applied to the environment of household commercial power AC220V, are designed in high power, and are not applied to the market of household appliances with power of tens of watts (AC is alternating current).

In order to meet the living demands of people, household electrical appliances often need to carry out some speed regulation control on a motor. The traditional single-phase alternating current asynchronous motor is difficult in speed regulation, an additional speed regulation controller needs to be added, and a low-cost and low-noise stepless speed regulation mode cannot be realized.

In order to solve the problems, the utility model provides a wireless remote control intelligent integrated motor. The stepless speed regulation of the motor can be directly realized in a remote control mode without an additional controller.
