I. Home appliance market and EMC demand pain points
With the continuous promotion and popularisation of 5G technology in the market, the degree of intelligence of home appliances is also increasing, such as remote control, WIFI function, and 5G technology is also being popularised in home appliances. The use of 5G technology on some home appliances such as home juicer, blender, soymilk machine, to a large extent for the working class or out of business people can remote control or at home mobile phone can control, realize the home to enjoy the food or at home mobile phone control machine at the same time to deal with some of the functions of the house and so on; a large degree of time saving, convenient life; the current market juicer, blender, Juicers, blenders, soya bean milk machines on the market generally use series excitation motors as drive motors.

At present, there are many types of such home appliances on the market, basically using the controller circuit board to increase the number of electronic devices to solve the EMC programme, and at the same time, due to the continuous updating of 5G and WIFI technology and the popularity of the application, the EU has issued a new version of the EMC standard, the EMC requirements of the upper limit of the frequency of the radiation of the space from 1GHz to 6GHz, the original series motor can not be passed the test or to solve the EMC to increase the number of electronic parts caused by the cost of home appliances. A large number of electronic parts caused by the high cost of home appliances has always been the existing market is difficult to solve the problem.

Second, Saixing in the EMC optimisation of technical precipitation
In order to solve the existing market EMC of home appliances on the space radiation frequency limit from 1GHz to 6GHz and high cost of various problems, Sai Xing motor in the series excitation motor through the use of new commutator and motor structure, improve the production equipment and technology, from the commutator design, motor structure and process to make adjustments, while adjusting the winding equipment and tooling accessories and motor rotor welding, etc., to solve the commutator changes Bring the hidden danger of premature failure of the motor life, and at the same time make the life of the motor is generally extended by more than double, can be up to 200 hours or more; in the motor to solve the 6GHz EMC, greatly save the cost of finished home appliances, but also optimise the finished home appliance circuit board, save space, and improve the competitiveness of home appliance products on the market.

Third, the development direction of EMC optimisation
Series excitation motor Sai Xing motor existing design is to optimize the new commutator and motor structure, improve the production equipment and process; due to the new commutator there is a slow production efficiency of the motor rotor problem, the follow-up Sai Xing electric opportunity to continue to test other solutions to solve the problem; at the same time, with the continuous changes in the market, home appliances, the development of intelligent home appliances, the market for home appliances, the function of the requirements of the product also continue to increase, the follow-up Sai Xing electric opportunity to In-depth study of the series excitation motor forward and reverse function to meet the new 6GHZ EMC requirements while taking into account the market demand for high power and long life of the motor.
