Electric Car are now very common, so the application of Electric Car is increasing. However, we will also encounter some common faults during use. Let's take a look at them together:
1. Loud noise is a common problem. The main reasons are:
① Large bearing clearance in the motor.
② Motor rotor sweeping.
③ Loose and falling magnets.
④ Axial movement inside the motor.
⑤ Oxidation, ablation, oil stains, unevenness, and loose commutator segments on the commutator surface of the brushed motor.
2. The lack of display on the instrument panel is a common fault in Electric SUV Car. The main reasons are that there is no voltage between the positive and negative leads of the instrument, the wires or connectors are short-circuited, or the instrument is damaged.
3. If the wheels turn as soon as the power is turned on, and the incremental speed is very fast, this fault is called "flying car", which is mostly caused by the poor contact cycle of the ground wire of the handle, or it may be a controller failure.
4. The horn is out of control. It is mostly caused by damage to the horn, damage to the switch, or short circuit of the connecting wire or connector. These aspects are mainly checked during maintenance.
These are the main common faults of Electric SUV Car. Everyone must operate them correctly according to the instructions so that their performance can be fully demonstrated.
