What are the causes of motor overheating in new energy vehicles?

[JackRose]

Here are the reasons for motor overheating in new energy vehicles: 1. Internal motor failure: caused by bearings. Bearings support rolling speed, and once the gap between steel balls increases, it can lead to carbon burning inside the motor, friction between the stator and rotor, increased effort and heat, greater friction, and rising temperatures. In this case, high-quality bearings need to be replaced. 2. Braking system issues: Friction from the braking system in electric vehicles can cause motor overheating due to the following faults. 3. Brake line problems: Long-term use can lead to rusting at both ends of the brake line due to water ingress or damage to the outer casing at the bottom, resulting in improper braking and increased motor temperature.
