What is the difference between a brushless motor, a brushless motor and a brush motor
Brushless motor without carbon brush, drive circuit, chip design and programming, in used in the field of automation, brushless motor is don't need encoder, brushless motor by sensing the Honeywell to the rotation of the induction motor, the induction signal feedback to the control chip.
Brushless motor, strictly speaking is including servo motor, stepper motor and general brushless motor, practical application, we usually refer to the brushless motor are ordinary brushless motor, because of the expensive servo and stepper price, can only be used in the field of automation to apply daily.
The difference between a brush motor and a brushless motor:
1, brush motor
It adopt carbon as the two contacts of the motor power supply, using speed control switch and controller to control, through the gear second deceleration and an overrunning clutch to achieve electric bicycle 0-20 km / h stepless speed regulation. Currently the have high gold and brush motor speed, motor speed reduction gear strength strong, good wear resistance, design reasonable, so the repair rate is low; and maintenance to replace the motor gear and the cost is less, effectively reduces the electric bicycle maintenance costs; and brush electric machine can be through an overrunning clutch and flywheel to achieve easy human riding. Brush motor is the use of brush mechanical reverse!
2, brushless motor
The speed control system of the speed control system is higher than the speed control system of the brush high-speed motor, and the controller is easy to be used in the control system. With no brush motor electric bicycle speed must be to 35 km / hour or more, in order to play the best efficiency, but we know electric bicycle as a non motor vehicle management, speed must be in the 20 km / h following, so there is no brush motor is selection of electric bikes and reduce the working efficiency, desirable is not strong. Now it is used the main point is that the noise is small. Brushless motor is the use of electronic circuits to change!
The following from a few aspects to talk about the difference between a brush motor and brushless motor:
1, the scope of application:
No brush motor equipment can be used in the dairy industry, brewing industry, meat processing industry, soybean processing industry, beverage processing industry, pastry industry, pharmaceutical industry, precision electronics factory, some higher requirements such as dust-free workshop, like Dior electrical production and non brush motor (DIHOUR) for dry hands, the use of factory more.
Motor carbon brush: can only be used in all kinds of toilet and the area requirements are not too high, and like a dustless workshop and explosion-proof workshop cannot be used!
2, service life:
Brushless motor: can work continuously for 20000 hours or so, the normal service life of 7-10 years.
Brush motor: 1000-5000 hours of continuous work, the life of 1-2 years.
3, the use of effect:
Brushless motor: 90-95m/s high-speed operation, the actual effect can reach 5-7s dry hand time.
Brush motor: running speed and drying time is far lower than the brushless motor.
4, energy saving:
Relatively speaking, the power consumption of brushless motor is brushless 1/3.
5, future maintenance
Carbon brush motor wear, not only replace the carbon brush, also replaced the switch gear motor peripheral accessories, the cost is much higher. The most important is that the overall function will be affected.
6, noise and service life
Noise emitted by motor carbon brush than non brush motor was much higher, and with the future of the carbon brush wear, brushless motor, noise will be more and more big, and no brush motor is not affected.
