Which is better for the brush motor or the brushless motor of the muscle massage gun?

 

Muscle massage gun is an effective method to treat soft tissue pain imported from abroad. It is through high-frequency vibration, deep penetrating muscles, directly hit the deep muscles, and then play a role in effectively alleviating muscle tension, to achieve the purpose of pain relief. The key to playing the role of the massage gun lies in the motor. There are two types of brushless motors and brushed motors on the market. So which is better, a brush motor or a brushless motor for the electric massage gun?

 

Which is better, a brush motor or a brushless motor for the gunmassage gun?

1. There are many differences between a brush motor and a brushless motor for the body massager gun. 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. The brush motor of the fascia massage gun is a rotating motor that contains a brush device that converts electrical energy into mechanical energy (motor) or converts mechanical energy into electrical energy (generator). 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 of the portable massage gun 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 and variable frequency speed regulation, and it will not oscillate and lose step when the load changes suddenly.

 

3. The power massager gun’s 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, fascial gun massagers using 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 professional massage guns on the market now use brushless controllers, and those with brushes have basically been eliminated.

 

4. In the actual production process, the brushed and toothed DC motor of the percussion massage device 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.
