Electric bicycle motor brush is good, or no good brush, and what is the difference between the two?
Brushless low speed motor is selected by electric bicycle, also known as brushless gearless motor. It is more current and weak in electric bicycle starting and climbing. It is seldom used by manufacturers at present.Brush speed motor (3600 RPM / minute) is currently most of the domestic electric bicycle manufacturers selected, it adopt carbon as the two contact of motor power, the use of speed controller to control and turn, through two gear deceleration and overrunning clutch to achieve electric bicycle 0-20 km / h stepless speed regulation. The currently used brush high speed motor motor reduction gear high gold content, strong intensity, good abrasion resistance, reasonable design, so the repair rate is low; and the maintenance and replacement of gear and motor cost less, reduce the maintenance cost of electric bicycle; and brush electric machine can be achieved easily by overrunning clutch and flywheel human riding.
The motor is the main driving part of the electric bicycle, which is the heart of the electric bicycle. The motor has a direct impact on the performance of electric bicycles.According to industry experts, at present, the domestic electric bicycle motor mainly has brush motor and brushless motor two kinds; brush motor and high speed and low speed points.
Brushless motors are currently used by electric bicycle manufacturers, usually brushless brushless motors. Its speed control system cost is higher than the speed control system of the brush high speed motor, and the controller is prone to malfunction in use. Electric bicycle with brushless motor driving must reach a speed of 35 km / hour or more, in order to exert the best efficiency, but we know that the electric bicycle as a non motor vehicle management, must be in the speed of 20 km / h, the brushless motor is electric bicycle with reduced work efficiency, it is not strong. The main thing that is being adopted now is the small noise.
