First, the principle of the muscle fascia gun

The fascia gun uses its internal special high-speed motor to drive the “massage head”, generating high-frequency vibrations to the deep muscles, reducing local tissue tension, alleviating pain, and promoting blood circulation.
The fascia gun transmits force and vibration to the fascia of the human body through high-frequency vibration (2000-3200 times/min), thereby increasing the blood flow of the tissues, relaxing the muscles, and can make the human tissues relative displacement through resonance , Reduce tissue adhesion, restore the elasticity of muscles and fascia, relax the tense and stiff fascia, and relieve some of the discomfort symptoms of the human body.

Second, which is better, a brush motor or a brushless motor for the Fascial Gun?

1. There are many differences between a brush motor and a brushless motor. From the name, we can see that the brush motor has carbon brushes, and the brushless motor does not have carbon brushes. When the motor with brush motor works, the coil and commutator rotate, but the magnet and carbon brush do not rotate. The alternating change of the coil current direction is completed by the inverter and the brush that rotate with the motor.
2. A brush motor is a rotating motor that converts electrical energy into mechanical energy (motor) or converts mechanical energy into electrical energy (generator) with a built-in brush device. The brush motor is the basis of all motors. It has the characteristics of fast starting, timely braking, smooth speed regulation in a large range, and relatively simple control circuit.
The brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product. Since the brushless DC motor runs in a self-control mode, it will not add a start winding to the rotor like a synchronous motor that is started under heavy load under variable frequency speed regulation, and it will not oscillate and lose step when the load changes suddenly.
3. The brush motor is a traditional product with relatively stable performance. The brushless motor is an upgraded product, and its life performance is better than that of the brush motor. However, its control circuit is more complicated, and the requirements for aging and screening of components are stricter. Although the motor has a long life, the control circuit is prone to malfunctions. Therefore, the selection of brushless motors must undergo rigorous reliability tests to ensure quality. However, with the continuous upgrading of technology, the brushless motor technology has become quite mature. At present, all the current controllers are brushless, and those with brushes have been basically eliminated.
4. In the actual production process, because the brushed and toothed DC motor is a high-speed motor, the teeth of the gear are small and easy to wear, but the force is large and the climbing ability is strong. The brushless DC motor saves two or three years of the trouble of changing the carbon brushes during use. However, due to the process of controlling the brushless motor, extremely high precision is required. Moreover, the price of brushless motor controllers is also higher. In contrast, a DC motor with brushes and gearless, although it is necessary to replace the carbon brushes, it is very easy to replace the carbon brushes, and the control of the motor is relatively simple, the motor runs smoothly, and the safety factor is high.
