1 those who understand electric machinery principle ask what how change electric machinery of alternating current fan into ～ ～ ～ to change direction
My electric machinery wiring is, red, green, yellow, now red yellow receive capacitor, next, red green receive 220V alternating current, fan turned now, the wind that but blow,goes out returns way, how to let electric machinery turn over directional movement?
The problem is additional: AC 220V
Capacitance wiring is not moved, green line is not moved, get off line of power source input from red line, it is OK on Huang Xian to receive.
Is rotor of 2 fanner electric machinery used need not go up oily?
Electric machinery gives out heat badly.
The bearing of fanner electric machinery is oiliness bearing, new can not cheer inside a year, answer every year later last time
Why does 3 fanner electric machinery have 3 lines, what are these 3 lines, how to receive, I want to measure stand or fall how to be measured with avometer
My fanner is slower than before I just had been cleaned again put oil still is slow 5 archives resemble the 1 archives when before same, which is I also do not know bad I just got an avometer I think the volume falls, do not know how to be measured, if be measured so that I can change east east, do not know capacitance or electric machinery to broke a short circuit or me to wash the electric machinery that receive a fault namely now. The line between capacitance.
The problem is additional: You say this measures electric machinery by turns with avometer 3 wiring head, block value is the least give priority to winding (receive power source) , block value is the greatest for (auxiliary winding) receive capacitance that avometer needle a wiring, a needle is nodded again (receive) which. Won't be I still used won't avometer express a needle 2 times to receive thrum / ?
Above all you twist one lower shaft whether of the activity, if inactive you can use left and right sides of small hammer fluctuation to be patted a few times, if axial activity if still be no good, gauge electric capacity, what hold the polar contact phone of avometer is polar, if avometer finger is not moved or can be moved and won't clear, change capacitance, receive wrong line if capacitance is in good condition also likely, measure electric machinery by turns with avometer 3 wiring head, block value is the least give priority to winding (receive power source) , block value is the greatest for (auxiliary winding) receive capacitance, remaining that is public head (receive power source and capacitance) , when line encircles block to be worth, among them addition of value of two groups of block is equal to advocate winding block value, criterion electric machinery coil has break a short circuit.
Why does 4 fanner electric machinery have 5 lines?
Why does domestic fanner electric machinery have 5 lines?
Be because there are 5 windings,be because,still can is speed change other perhaps? Thank! ! !
