    AC Universal Motor EMC Optimization Technology for 5G and WIFI Application

    2022-03-09 15:37:49 80

    1. 5G technology is widely used in home appliances

    With the continuous promotion and popularization of 5G technology in the market, the intelligence of home appliances is also constantly improving, such as remote control, WIFI function, and 5G technology is also popularizing in home appliances. The use of 5G technology on some household appliances such as household juicers, blenders, and soymilk machines is largely for office workers or business people who are away from home to be able to remotely control or control them from home by mobile phones, so that they can enjoy food when they are at home. At home, the mobile phone controls the machine and handles some functions such as housework at the same time; it saves time and facilitates life to a large extent; at present, the juice machine, blender and soymilk machine on the market generally use the series motor as the driving motor.


    2. EMC new standard for AC universal motor

    At present, there are many kinds of such household appliances on the market, and they basically use the addition of electronic devices on the controller circuit board to solve the EMC solution. At the same time, due to the continuous updating and popularization of 5G and WIFI technology, the European Union has promulgated a new version of the standard for EMC, requiring EMC to The upper limit of the frequency of space radiation is increased from 1GHz to 6GHz. The original AC Universal motor cannot pass the test or the high cost of household appliances caused by the addition of a large number of electronic parts to solve the EMC problem has always been a difficult problem for the existing market.

    3. Motor EMC Optimization Technology for 5G and WIFI Application

    In order to solve the problems of increasing the upper limit of the frequency of space radiation from 1GHz to 6GHz and the high cost of home appliance EMC in the existing market, Power Motor has improved the production equipment and process by adopting a new type of commutator and motor structure on the series motor. In order to solve the problems of increasing the upper limit of the frequency of space radiation from 1GHz to 6GHz and the high cost of home appliance EMC in the existing market,Power Motor has improved the production equipment and process by adopting a new type of commutator and motor structure on the series motor service life is generally more than doubled and can reach more than 200 hours; the 6GHz EMC is solved on the motor, which greatly saves the cost of finished home appliances, and also optimizes the finished home appliance circuit boards, saving space and improving the competitiveness of home appliances in the market.


    4. EMC technical optimization direction of home appliance motor 

    The existing design of the AC Universal motor from Power Motor is to optimize the new commutator and motor structure, and improve the production equipment and process; because the new commutator has the problem of slow production efficiency of the motor rotor, the follow-up Power Motor will continue to test other solutions to solve this problem; at the same time, with the continuous changes in the market and the intelligent development of home appliances, the market's functional requirements for home appliances are also increasing. In the follow-up, Power Motor will conduct in-depth research on the forward and reverse functions of series motors to meet the requirements of the new 6GHZ EMC. It is required to take into account the market demand for high power and long life of the motor at the same time.
