High-Speed Electric Motor 1, Before each experiment, the friction wheel must be polished and polished with ordinary oil, otherwise it will affect the correct effect of the experiment 2, to do four tests, 1, ordinary oil test, 2, adding anti-wear agent oil test, 3, oil test, 4, repair test. Before each test must be grinding wheel clean, otherwise the test results are not accurate, grinding wheel clean standard is normal operation without noise 3, the weight of the weight on behalf of the pressure on the contact point, the size of the ball marks on behalf of the wear resistance of lubricants or anti-wear agent. Changes in the amount of weight equivalent to change the size of the pressure on the contact point 4, until the normal operation of the motor can be placed on the weight gently, the time interval of about 3-5 seconds. Added to the weight of ordinary lubricants to lose lubrication is locked, the engine stops rotating so far. At this moment, turn off the power immediately to prevent the motor from burning out 5, check the amount of weight (lubricity), observe friction pad wear (abrasion resistance), Manufacturer: MERHOVO
