The core design logic of multi-level sealing rings lies in constructing a composite sealing system of "barrier-absorption-compensation" by arranging sealing units with different functions in layers.
The drive motor rotor dynamic balancing plate plays a dual role as a "microscopic quality inspector" and a "precision surgeon." Its ability to capture and correct micron-level mass eccentricity does not rely on brute force alone, but rather on a high-sens
The material must have good chemical corrosion resistance to resist the erosion of media such as lubricating oil and coolant inside the motor and prevent the risk of leakage caused by material degradation.
The assembly of the front cover and the stator is usually achieved by using locating pins or stop structures for initial positioning, and then by using bolts for final fixation.
The compression of the sealing ring needs to be precisely controlled to avoid accelerated aging due to over-compression or leakage caused by insufficient compression.
In the core power system of new energy vehicles, the drive motor is not only the hub of energy conversion but also a key component determining the overall driving experience.
