The part of new energy vehicles uses ceramic bearings
In new energy vehicles, ceramic bearings are mainly used in the motor part of electric drive systems. Specifically, the following are some common application scenarios:
1. Electric motor: The electric motor of new energy vehicles is one of the core components of the vehicle, usually using permanent magnet synchronous motors or asynchronous motors. In the supporting and load-bearing parts of the rotor and stator of the electric motor, ceramic bearings can provide high hardness and wear resistance, ensuring the operation and long service life of the motor.
2. Motor reducer: Due to the fact that the motor of new energy vehicles usually has high speed and low torque, in order to match the power demand of the entire vehicle, it is necessary to convert the high-speed rotation of the motor into the torque and speed required for the wheels through the reducer. Ceramic bearings can play a role in supporting and transmitting torque in reducers, while possessing the characteristics of high wear resistance, low friction, and high speed.
It should be noted that there may be slight differences in the ceramic bearings used in new energy vehicles by different vehicle models and manufacturers. The above mentioned are some common applications, and the specific application needs to be determined based on the specific vehicle model and manufacturer's design selection.
