What's the matter with the failure of the new energy drive motor?

[MacEmerson]

Reasons for the failure of the new energy drive motor: damage to the power transistor in the controller, damage to the motor. Damage to the power transistor in the controller: Because the phase line (the connection line between the controller and the motor) is disconnected, the motor rotation will become lighter. The motor will only lock up when the phase line is short-circuited, and the phase line will short-circuit when the power tube in the controller is broken down. Motor damage: When the car starts, only the electromagnetic switch of the starter makes a strange noise, but the crankshaft does not rotate. This phenomenon belongs to the fault of the battery disconnection. The user can replace it. When the engine fault light is on, the vehicle can be started and turned off three times in a row, or the negative terminal of the engine battery can be disconnected and then reconnected after 30 seconds.
