Now we go out of the tools is more and more, the distance is not far, riding a small electric donkey or stepping on a balance car, electric skateboard and so on is particularly convenient.

But sometimes it is inevitable that the car suddenly does not work, and the confusion is particularly troublesome. At this time, is there any simple method that can help us make a rough judgment and let the small problem be solved by itself? Big problems can also be divided into priorities, easy to find someone to repair?

Today, I will share with you a way to quickly judge the most critical part of the motor wheel on the car, without the need for special tools and knowledge, ordinary people can quickly judge，the steps are as follows:

First of all, the car will be powered off the motor wheel overhead, followed by the motor wheel and the controller connector separate, let the motor three thick wire connector separate, use the hand to move the motor wheel to make it rotate, note that the motor wheel resistance should not be large, and then the motor three thick wire of any two wire metal head directly short close together, then use the same force as before to move the motor, Pay attention to the resistance of the motor wheel at this time.

Normal if the motor three thick lines two to two short-circuit, three kinds of connection under the motor wheel rotation resistance is significantly greater than no short-circuit, then it proves that the motor wheel is good, the cause of the fault is likely to be caused only by poor line contact, at this time only check the motor and controller, controller and other control switch between the key contact is bad, More than 90% of problems are eliminated almost immediately.

If the three thick lines of the motor are shorted, as long as there is more than one motor wheel rotation resistance does not increase in the middle, it can be judged that the motor wheel line is broken or damaged, at this time, you should go to a professional repair shop to ask the master for detailed maintenance.
