The motor is an important part of an electric vehicle. If it does not work well, the electric vehicle will go on strike. What should I do if the electric vehicle motor fails? The editor will give you tips.

①The fuse is blown

This is a small problem, just replace the fuse for a small fee.

②The power switch is broken

Replace the power switch. This is a bit more troublesome and requires tools.

Judgment method: Turn on the power switch and use a multimeter to measure the resistance between the input and output of the power switch. If the resistance value is zero, it is normal. If the resistance value is infinite, the power switch is broken and the power switch should be replaced.

③Hall turn is broken

Diagnosis method: Use a multimeter to measure the output voltage of the green wire at the output end of the handlebar. If there is a voltage output of 1-4.2, the handlebar is normal. If there is no voltage output, the handlebar burns out and needs to be replaced.

④The controller is broken

Detection method: Use a multimeter to measure the red wiring at the output of the controller (connected to the plug of the handlebar) with a multimeter in the DC voltage file. If there is a voltage output of about 5 volts, the controller is normal. If there is no voltage output, the controller is burned out and needs to be replaced. Device.

⑤The thread is loose

Please check each plug of the motor again to see if there is any bad contact. Or the battery box is not in place when it is put into the frame, and the contacts are not in good contact.

⑥ The motor burns out

This is the situation that everyone is most afraid of, and replacing the motor is very expensive.

Detection method: disconnect the connection between the motor and the controller, connect the rest of the wires, slowly rotate the motor, measure the Hall wire with a multimeter to see if there is a voltage change in the signal, if there is no change in one phase, it is the motor Hall The components are burned, causing phase loss, and the motor needs to be replaced.
