Description

Technical Field

[0002] The controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reversal of the motor. It consists of a program counter, instruction register, instruction decoder, timing generator and operation controller.

[0003] According to the current international definition of reliability, reliability refers to the ability to complete specific functions under specific time and conditions. Therefore, the reliability of the electromagnetic controller refers to the ability of the electromagnetic controller to successfully complete the work required by the entire system when the electromagnetic control system operates in a normal and safe state and does not affect the stability of the electromagnetic system.

[0004] In the prior art, when testing the electromagnetic controller, only the electromagnetic compatibility test is performed to check whether the electromagnetic generated during the use of the electromagnetic controller affects the use of other electronic components. At the same time, whether the electromagnetic generated by other electronic components when working affects the use of the electromagnetic controller, that is, the electromagnetic compatibility test, but the working environment of the electromagnetic controller is not tested. If the use environment of the electromagnetic controller is relatively harsh, it is easy to cause damage to the electronic components inside the electromagnetic controller, resulting in damage to the electromagnetic controller, which reduces the scope of the test.
