Electric Bicycle Controller Depending on the motor

Electric car controller is the electric car's brain, used to control the electric car motor to start running the device, without his electric car will be in a state of paralysis, can not work properly. Electric car charger agent to introduce you, electric car controller is divided into brush controller and brushless controller two different operating principle of different controllers, there are differences in the use of methods.

Electric car charger agent first introduced to you two different controllers, the controller is based on different motor manufacturing. Brush controller motor must be a brush motor, that is, the motor input current is DC, the controller only need to provide different sizes of current can speed, and simple design, easy to understand. The brushless controller control motor must be a brushless motor, in fact, is a three-phase AC motor, the controller converts the DC into three-phase AC power, through the sensor components in the motor commutation, never reached the normal operation of the motor the goal of. Complex design, high cost.

Electric car controller agent stressed that the brushless controller is a brush controller on the basis of the transformation made by the update, than the brush charger long life, starting a strong power, maintenance-free. Electric car brushless controller is the most popular electric vehicle power source. When we buy electric cars we have to look at the circuit diagram in detail, there are two lines of the motor is a brush controller, eight lines must be a brushless controller. Any thing has his life, of course, electric car controller is no exception also need our daily maintenance and maintenance! Here let Xiaobian simple to tell you about:

Electric vehicle controller life and maintenance, usually pay attention to the appearance of the controller is conducive to heat dissipation, heat dissipation conditions will be extended life.

Special attention, the controller lead plug cleaning will also extend the service life, which is also affecting the controller of the weak links, when the controller lead plug received rain soaked rain, the timely cleaning with water or alcohol to avoid oxidation Rust, to prevent the connection caused by false controller failure. The main phenomenon of high voltage failure is the indicator light does not shine, which features a fuse blown, rectifier diode D1 breakdown, capacitor C11 drum package or burst. Q1 breakdown, R25 open circuit. U1 7 feet short to ground. R5 open circuit, U1 no starting voltage. Replace the above components can be repaired. If U1 7 feet above 11V voltage, 8 feet 5V voltage, indicating U1 basic normal. Should focus on the detection of Q1 and T1 pin whether there is Weld.
