According to relevant information, the pace of life continues to accelerate.Today, around 75% of the world's population is suffering from "sub-normal" disease. With the development of the national economy and living standards, people have also begun to pay attention to their own  health question. Massage health care is a traditional Chinese skill, it is through non-drug ways to help us get rid of the "sub-health" state. Modern medical research has proved that circular massage on special acupoints is effective.Such as our respiratory system, digestive system, nervous system and blood circulation. The ring system has the function of maintaining and improving disease resistance and can help us get rid of the "sub-health" problem as soon as possible. There are two main ways of health care, one is manual massage, the other one is automatic instrument massage, such as electric massage chair. Be compared to Manual massage, automatic machine massage with its low cost, action hand

In recent years, the diversity of law and other characteristics have been welcomed by more and more people.In the automatic massage equipment, the electric massage chair is the most popular one a kind of massage machine.

At present, most of the popular electric massage chairs in the market are using Brush DC motor due to its mature structural design, Simple control, cheap price and other characteristics. It has been widely used. With the popularity of motor massage chairs in the market, the disadvantages of brush motors also gradually emerged, such as running noise problems, motor life questions. The problem of electromagnetic radiation generated by the motor rotation process and so on. For structural reasons of brushed DC motors, these problems cannot be solved completely. For example: brush DC motor electromagnetic radiation is mainly caused by the constant commutation of the internal brush and commutator blade during commutation, and the brush and commutator blade are an essential part of the brush DC motor, so it is accompanied by the generation of electromagnetic radiation at all times during the rotation process.

Compared with the brushless DC motor, the brushless DC motor eliminates the mechanical commutation mechanism of the brushless DC motor and adopts the commutation mechanism of electronic commutation, thereby overcoming the electromagnetic radiation problem caused by the commutation of the brushless DC motor, and has the advantages of more reliable operation stability, durability and good speed regulation performance. The brushless DC motor is now used to replace the brushed DC motor, and at the same time, for the characteristics of the electric massage chair, a set of control system matching the brushless DC motor has been developed, replacing the common brushed motor on the existing market, so as to solve the problems of short life, poor reliability and electromagnetic radiation of the brushed motor. Each control circuit board is small in size, low in cost, easy to transplant to the existing massage chair system, and easy to promote.
