One is the flexible fault: the so-called flexible fault refers to sometimes appears, sometimes does not appear, or the fault has no obvious rule to follow, such as the controller in the copper wire welding, sometimes contact well. Normal operation of motor; Sometimes the motor will start powerlessly if it is not in good contact.
This kind of fault must first analyze the related aspects and measure the relevant parameters. If there is no clue for the time being, the simplest and most effective method is to change the parts, for example, electric bike wheel.
A kind of rigid fault: the so-called rigid fault, refers to this kind of fault once it occurs always unchanged, the fault range does not expand, does not transfer, the fault phenomenon does not change.
If the power brake is damaged, it is impossible to cut off the power supply of the motor, and can be replaced by a new product. This kind of fault is relatively easy to repair. The general understanding of a bit of theoretical knowledge can judge first and then change the parts to improve the rate of maintenance.
The maintenance has one principle that is to minimize the principle. The simple question itself has been minimized, the complex problem is to grasp the key point of the problem, find a solution to the breach.
If a car does not rotate the steering motor, the display work is not normal, the display can be disconnected first, only connected to the motor, battery and controller can be measured parameters analysis, such as the normal operation of the motor. Check the monitor again.
