What are the consequences of the wrong connection of an electric bicycle battery?
An electric bicycle driven by a direct current motor when the line is reversed:A may be turning, not turning, or accompanied by humming. Brushless motor.B, it's possible to reverse. Old fashioned brush motor.C, if the wrong connection time is too long: the motor, controller may burn down
This should be divided into circumstances, and now more and more complex electric cars, more sophisticated. However, "advanced" is also a direct current motor to drive the wheel of the machine". Therefore, the focus on the DC motor, the line as long as the aging is not excessive, or "wrong time" too long, or should not be too serious.
Recommendations and related knowledge:1, not familiar with or without relevant knowledge, do not start hand in hand with professionals.2, familiar with the professional knowledge, pay attention to distinguish a brush or brushless connection, the most stupid way is how to remove, how to install wiring, general original line (not modified) will have their own color, correspondence is.Special note: the electric wire of the motor is called the phase line, not the daily power line, that is, there is no saying "ACC" or "Chang (+)" on the car. The brush motor is unidirectional, and the brush is three-phase.3, answer: (at present the most non brush as an example)Brushless motor: its coil lead line is usually 3, and the hall lead has 5, a total of 8 root, these lead must correspond with the controller corresponding lead, otherwise the motor can not rotate normally. There is a knowledge of the controller's correlation with the phase angle of the brushless motor. Such as the controller to phase angle, braking potential, adaptive current, etc., its function is more complex. Generally speaking, there are many kinds of models on the market at present.The answer is varied. But the wiring principle is similar. If the single finger motor line, as long as the positive and negative poles are not reversed, the 3 (lead line) coarse corresponding to the other 3. Basically in order of color in order to butt (specifically due to vehicle design standards prevail, here only for example), each time after the completion of the key to open and turn the handle, to see whether the motor rotation "state" is normal. Until the normal direction of rotation.
