[0002] High-voltage motors are electric motors with a rated voltage of more than 1000V. Such motors are widely used in industrial production, transportation and other fields. In high-voltage motors, due to the high voltage and relatively small current, the heating and loss of the wires are reduced, thereby improving the working efficiency and reliability of the motor.

[0003] After high-voltage motors are manufactured and shipped from the factory, they need to undergo a pressure test on their motor casings to ensure the motor's stability during use. During the test, the motor casing to be tested needs to be placed on the sensor of the test bench, and pressure is applied to the casing to test the motor casing's pressure resistance.
