Whether it is for a fit body or a healthy body, exercise is an indispensable thing. Exercise can not only enhance our physique and improve our sub-health state, but also increase the strength of our muscles and the beauty of body lines. In addition, it can also stimulate the secretion of dopamine, which is conducive to the release of stress and the improvement of mood.

However, for a novice, whether you just got a fitness card or go for a night run on your own, you will encounter a problem. If you do not perform a good warm-up and full-body stretching exercise before exercise, your legs are prone to twitching after exercise. In addition, improper exercise can cause the doubling of muscle soreness and cannot be resolved. It can only recover slowly over time, so stretching and massage before and after exercise is very necessary.

Want to relax your body completely, but are too embarrassed to ask others for help or go to a professional masseur to be too expensive and troublesome? Buying a professional massage gun can help solve these problems. It can not only help stretching but also massage the muscles to speed up the decomposition of lactic acid in the muscles.

However, many novices are confused when they face the various massage guns and various publicity gimmicks on the market.

Here are the two questions most asked and confused.

Is the more gears of the massage gun, the better?

Of course not. There are many massage guns on the market that are adjustable with 20 gears and 30 gears as a selling point. In fact, the difference between each gear is only 100rpm. The difference between 100rpm is actually very weak, especially when it is used. The difference between three or four gears is not much different for users. Therefore, for users, 3-5 gears are enough to meet various daily needs.

What is the difference between a brushless motor and a brushed motor?

The advantages and disadvantages of brushless motors:

Advantage:

1. Low running sound

In daily life, we need to reduce noise to protect our sound environment. The most important thing now is to use it in quiet places such as hospitals, banks, airports, schools, etc., where quietness is required. Even if it is used at home, low noise is a relatively rigid demand for users. To

3. Long life

Because it replaces the commutator and carbon brush with a controller, it is several times or even ten times that of a brushed motor. The life of carbon brushes has a certain limit. For example, the carbon brushes will wear out after a thousand hours. Only the brushes can be replaced, but the motor can be replaced. To

4. High speed

Because of the use of magnetic field induction, there is no substantial contact speed that can be made faster. 

Shortcoming: 

1. High cost

The cost of the controller increases by at least one hundred yuan. Take the micro motor as an example. The cost of the original commutator and carbon brushes is much lower. The high-quality fascia guns that use brushless motors as the power system generally sell for $310-465, and the cheapest ones cost $62-78.

Our massage gun uses a high-quality brushless motor, equipped with a smart electronic display and a unique anti-allergic silicone massage head. In order to open the market, the sale price of this fascia gun is only 35 US dollars, and can be provided according to customer needs Customized service, this product has both excellent quality and favorable price.

2. If the environment used is in a place with a high magnetic field or has been in contact with or very close to a high magnetic field, the motor will lose its function

Because the rotor part of the motor itself is made of magnets, it becomes magnetic only after magnetization. The high magnetic field will change the magnetic field of the rotor or eliminate part of the magnetic motor will not work normally.

Advantages and disadvantages of brushed motors

Advantage:

1. Simple structure

The brush motor has simple structure, easy production and processing, convenient maintenance, and easy control; the DC motor also has a fast response, large starting torque, and can provide rated torque performance from zero speed to rated speed.

2. Smooth operation, good starting and braking effect

The brush motor is speed-regulated by voltage regulation, so the starting and braking are stable, and it is also stable when running at a constant speed. The brushless motor is usually controlled by digital frequency conversion. First, the AC becomes DC, then DC becomes AC, and the speed is controlled by frequency change. Therefore, the brushless motor does not run smoothly when starting and braking, and the vibration is large, only when the speed is constant. Will be stable.

3. High control accuracy

Brushed motors are usually used together with gearboxes and encoders to make the motor output more powerful, with higher control accuracy. The control accuracy can reach 0.01 mm, which can almost stop the moving parts wherever you want. All precision machine tools adopt DC motors to control precision.

Shortcoming:

1. There is friction between the brush and the commutator, resulting in reduced efficiency, increased noise, and easy heat generation. The service life of a brushed motor is several times shorter than that of a brushless motor.

2. Maintenance is troublesome, and the brush needs to be changed constantly.

3. Because of the large resistance, the efficiency is low and the output power is low.

4. The friction between the brush and the commutator will cause sparks and cause great interference.

Therefore, if you don’t mind the loud noise and want an affordable price, you can buy a massage gun with a brush motor as the power system. If you want to meet the requirements of high quality, low noise, long service life, etc., and the budget is relatively sufficient, you can buy a massage gun with a brushless motor as the power system.
