Type freight electric vehicle controller

Currently, the principle of the cargo trikes controller circuit employed substantially the same or similar.
Brushed and brushless DC motors were powered by pulse width modulation PWM speed control method , just choose the drive difference circuits, integrated circuits , power transistor switching circuits and certain related functionality. Differences components and circuits on the same controller not constitute a performance. Controllers are two structurally, we call it separate and integral .
1 Separate : the so-called separation means separating the controller body and the display portion . The latter is mounted on the handlebar , the controller main body hidden in boxes or electric box , not outside. This approach allows the controller and power supply , shorten the distance between the motor connections , body appearance is concise.
2 -one : a control section and a display section into one, housed in a fine special plastic box. Box installed in the middle of the handlebar , there are varying amounts of open holes on the box panel , diameter 4 ~ 5mm, topical transparent waterproof membrane . Hole corresponding position with light-emitting diodes to indicate the speed , power and remaining battery power .
