What is a brushless motor, brushless and brush any difference?

Brush motors and brushless motors difference:

1, brush motor

It uses a brushless motor power supply as the two contacts by the governor and the controller is controlled by the second reduction gear and clutch to achieve the electric bike 0-20 km / h stepless. Currently used in high-speed motor that has a brush of high gold content, strong reduction gear motor strength, wear resistance, reasonable design, it is a lower failure rates; and less maintenance and replacement gears and motors cost effective to reduce the electric bike maintenance costs; and a brush motor can be achieved easily by human riding clutch and flywheel. Brush Motor is the use of the brush mechanically commutated!

2, brushless motor

Its speed control system cost than brush motor speed control system for a high-speed controller in use prone to failure. When equipped with a brushless motor bike traveling speed must be to 35 km / hour, in order to play its best efficiency, but we know that as a non-motor vehicles electric bicycles to manage, it must speed of 20 km / h or less, it is brushless motor is electric bicycles chosen to reduce the work efficiency, it is desirable not strong. It is now used in the main point is noise. Brushless motor that uses electronic line-commutated! Polarity detecting element detects!

Here to talk about several aspects of brush motors and brushless motors difference:

1, the scope:

Brushless motor device can be used: the dairy industry, the brewing industry, meat processing industry, soybean processing industry, beverage processing industry, pastry industry, pharmaceutical industry, precision electronics factory, and some more demanding clean room and so on, like Dior electrical capacity brushless motor (DIHOUR) dry hands, use the factory more.

Brushless motor: can only be applied to all kinds of toilets and other requirements are not too high for the region, but as clean room and workshop explosion can not be used!

2, life:

Brushless motor: can work for about 20,000 hours, regular life 7--10 years.

Brushless motor: it can work for about 5000 hours, regular life 2--3 years.

3, using the results:

Brushless motor: to 90-95m / s speed operation, the actual results can be achieved time 5-7s of dry hands.

Brushless motor: time running speed and dry hands is much lower than the brushless motor.

4, energy aspects:

In contrast, the power consumption of the brushless motor is brushless 1/3.

5, future maintenance

After the brushless motor wear, not only to replace the carbon brushes, also changing accessories and other electrical switch gear surrounding the cost much higher. Most importantly, the overall functionality will be affected.

6, noise and life

Noise emitted than brushless motor brushless motor much higher, and with the future of the carbon brush wear, brush motor noise will become increasingly large, and the brushless motor is not affected.
