The main difference between brushless motors and brushed motors

Brushless motors are commonly used to control devices with high requirements and high speeds, such as aircraft models, instruments, etc. Strictly control the motor speed to achieve high speed. In addition, the cost of motors and advanced hand dryer controllers was relatively high, so other equipment was later used.
1. A brushless motor consists of a motor body and a driver, and is a typical electromechanical integrated product. Due to the device operating in automatic control mode, it will not add another starting winding to the rotor like synchronous motors that start under heavy loads under variable frequency speed regulation, and there will be no oscillation or step loss during sudden load changes.
2. When the brush motor is working, the coil and commutator rotate, but the magnet and carbon brush do not rotate. The alternating change of coil current direction is achieved through the rotation of the commutator and brush with the motor.
3. Brushed motors are traditional products with stable performance. Brushless motors are upgraded products with better lifespan and performance than brushed motors, but their control circuits are complex and require strict screening for component aging.
4. Brushless motor equipment can be used in high demand dust-free workshops such as the brewing industry, meat processing industry, soy product processing industry, beverage processing industry, pastry processing industry, pharmaceutical industry, etc.
5. Brushed motors can only be used in places with low requirements, such as toilets, and cannot be used in dust-free and explosion-proof workshops.
6. Brushless motors can work continuously for about 20000 hours, with a typical lifespan of 7-10 years. Brushed motors can work continuously for about 5000 hours, with a typical lifespan of 2-3 years. In terms of energy conservation, the power consumption of brushless devices is only one-third of that of carbon brushes.
The above is an introduction to the differences between brushless motors and brushed motors. By understanding the knowledge of each product, we can fully utilize each product. If you have any other questions, you can follow our website and we will update you at any time.
