3. Stator vacuum testing machine detail pictures
4. After-sales service
4.1. Self-check: check the machine run smoothly or not and locate the fault modular automatically.
4.2. Check the fault via remote control
When the machine is in trouble, the after-sales service is not subject to the remote restrictions.
4.3. Modular design makes the after-sales quickly
Standard equipped with modular board card, which can be sent to the customer site immediately after positioning the failure.
5. The principle of testing the stator at vacuum environment
The movement of free electrons will generate static electricity, in order to generate a large amount of static electricity, a lot of free electrons need to move, which can be achieved by increasing the friction area and friction speed. And the atoms in the object move easily at higher temperature. For example: Clothes are easier to be dried at high temperature state. The same can be said for free electrons, which can easily move at high temperatures and carry positive and negative charges. Similarly, the lower the barometric pressure, the less bound the electron is subjected to, and the free electrons are easier to get out of their bondage and "muting" to one another. Therefore, in some electrical experiments, high temperature, low humidity and low pressure make the experiment succeed easier.
