How much do you know about the maintenance and servicing of electric motors in new energy vehicles? The drive motor is a critical component of new energy vehicles, so its maintenance, servicing, and fault diagnosis are of great significance. Only by enhancing technical skills related to the maintenance and servicing of drive motors can we promote the further development of new energy vehicles.
The daily maintenance of drive motors in new energy vehicles is crucial for ensuring their safe operation and extending their service life. The key points for the daily maintenance and servicing of drive motors in new energy vehicles are as follows:
First, check the coolant level in the motor controller and observe the coolant colour. If the coolant level is low, add coolant as required. If the coolant has an unusual odour or the colour has changed significantly, promptly visit a repair station to have the coolant checked and replaced. Inspect the motor cooling water pipes, especially the joints, for signs of ageing or cracking.
Second, inspect the drive motor’s fastening bolts and wire harness clips to ensure there is no loosening of bolts or clips.
Third, perform daily cleaning of the drive motor and its controller, removing any surface dirt. Carefully inspect the motor and controller surfaces for any damage or cracks. If cracks or mould spots are found, check for leaks. If unsure, promptly visit a service centre for inspection.
In addition to daily maintenance, regular maintenance and servicing of the drive motor is also essential to ensure stable operation. Use a lift to raise the vehicle and carefully inspect the exterior for cracks, scratches, dents, or leaks. Check if the paint marks on the motor mounting bolts have shifted. If shifted, tighten them to the standard torque.
How much do you know about the maintenance and servicing of electric motors in new energy vehicles? Following the above steps for motor system maintenance not only helps reduce the risk of faults but also enhances the driving experience. It is recommended that drivers incorporate these maintenance steps into their regular maintenance schedule to ensure vehicle performance and safety.
