Abstract
This article rests on the motor control technology and the monolithic integrated circuit technology development, embarks day by day from the people serious healthy problem, designs a section of function to be formidable, the low in price, the operation reliable and is advantageous for the massage which machine the people use. It has contained two big core technologies:
1.the PWM velocity modulation control direct current machine, PWM (Pulse Width Modulation, pulse-duration modulation) is loses using microprocessor's digit carries on the control to the analogous circuit one kind of very effective technology, the widespread application from the survey, corresponds to the power control and in transformation many domains.
2.The monolithic integrated circuit is nearly ubiquitous in present's electronic products, we may realize each kind of function through the software, the inexpensive cost is it does not become two electing. under the two big technology's supports, the massage machine may with ease realize its function, becomes the health care equipment's first choice.
