Inverter maintenance detection commonly used method, the dynamic test

ac electric motor stator copper winding 
Specifications
1. Material: silicon steel  
2. 20 years manufacturing experience 

3. competitive price,high quality
Dynamic test: after 3 phase induction motor the normal static test result, can dynamically test, namely the electrical commissioning. Before and after the electricity must pay attention to the following: 1, the electricity before, must confirm whether the input voltage generator is wrong, the 380 v power access to 220 v level of frequency converter will be Fried machine (Fried capacitors, varistors, module, etc.). 2, check the inverter after sowing mouth has been properly connected, whether there is loose connection, connection exception can sometimes water pump price lead to frequency converter failure, serious when a frying machine, and so on and so forth. 

Y2 series high power China ac motor

Specifications
1. effiency: IE2 and IE1 
2. 20 years manufacturing experience 
3. 12 months guarantee 

4. low noise and vibtration 
3, detect fault display content, such as transistors and preliminarily concluded that the failure and the reason. single phase induction motor 4, such as fault, not ac induction motor shown first to check whether there is abnormal parameters, and the parameter after resetting, the no-load without (motor) magnetic generator start frequency converter, and test the water pump price U, V, W three-phase output voltage value. Such as a lack of phase, three-phase imbalance, and so on and so forth, is a fault module or driver board, etc. 5, the output voltage is normal (shape phase, magnetic acmotor2.blogspot.com generator three-phase equilibrium), under the condition of load test. Test, it's best to full load test.
