Is it necessary to repair the broken motor of electric vehicle?

The motor of electric vehicle is broken and can be repaired.

It may be that the internal coil is burnt out, so it is better to replace it directly, but it requires some knowledge of maintenance principles, and most maintenance masters generally recommend replacing it directly considering the cost of manpower, material resources and time. After repair, the durability of the motor is not high and the maintenance cost is expensive. If it is damaged again, it may cause the controller to burn out.

In addition, in order to avoid troubles and disputes, the maintenance master will still choose not to repair the motor. Some customers feel a little thankless about the maintenance price and the troubleshooting methods after maintenance, and the motor is in a scrapped state, which will rust, wear, degauss, reduce endurance and increase load, so maintenance is really unnecessary. If it is used for a short time, it still needs to be maintained.

Repair of battery car motor fault;

1, the most economical thing is to find a repair shop. Motor damage may be Hall damage, coil burning or short circuit. Motor disassembly of Hall wire and coil is troublesome. The repair shop will suggest replacing the universal controller directly (without Hall line controller). If the coil burns out, it may be suggested to replace the motor. If it can be repaired, you can refuse to replace it and insist on maintenance.

2. The common faults of the motor are usually checked from its three components. First, check the motor body, then the position sensor, and finally the drive control circuit. There are many suspicious factors of fault, such as poor contact of motor winding, broken wire or short circuit, demagnetization of main magnetic pole of motor, coil burning, rust in water, etc. Position sensor: Hall element failure, poor contact, burning out, etc.

Drive control circuit: controller burnt out, overload, overvoltage or short circuit damage, poor line contact, etc. These should be checked one by one. The maintenance of the motor is complicated. Non-professionals should try not to repair it themselves to avoid damaging other components.
