Emu motor pressure ring: the “invisible guardian” of high-speed trains
In the modern high-speed railway system, the EMU motor is the core power source of the train, and the motor pressure ring, as a key part of the motor, is not well known but plays an indispensable role in the stable operation of the motor. It is the “guardian” of the motor rotor, ensuring the safety and reliability of the motor at high speed.
Function and importance of motor pressure ring
The primary function of the motor pressure ring is to fix and support the motor rotor. During the operation of the EMU, the rotor of the motor rotates at a very high speed, which generates substantial centrifugal force and thermal stress. If there is no fixed pressure ring, the rotor core may be displaced or deformed, which will affect the regular operation of the motor and even cause serious safety accidents. The pressure ring firmly fixes the rotor core to the rotating shaft by applying pressure to ensure its stability during high-speed operation.
In addition, the motor pressure ring also needs to withstand the mechanical and thermal stress generated by the rotor during operation. The motor speed of high-speed EMUs is usually up to thousands of revolutions per minute, which puts a high demand on the strength and durability of the compression ring. Therefore, the pressure ring is not only a fixed part of the motor but also a “fuse” for the safe operation.
