It got me about a week to rewind this engine. Most period i invested on calculation of fresh winding. I acquired a great deal of complications with calculation but we solved them and i obtained same guidelines of winding as were on previous one.
I got a lot of troubles with winding fresh winding too. Very first i made coils as well small, and i couldn'capital t insert final coils in slot machines. I couldn't entry to them because additional winding had been too little. Then i determine to create bigger one particular but i found problem once again. This period winding had been too big and i couldn'testosterone levels close the cover of engine.
Three-Phase AC Winding Calculations (single-speed windings) Kinds of diagrams This calculations program includes all necessary details for rewinding three-phase motors: the type of windings, number of layers, parallel circuits, span and number of turns per coil, number and cross section of turn in a slot, as well as the winding diagram. A single phase transformer is a type of power transformer that utilizes single-phase AC, which means the transformer depends only on a voltage cycle that operates in a unified time phase. It is used for power distribution. It accepts single-phase AC power and outputs single-phase AC power, at a higher or lower voltage level.
3rd period i successful rewind motor. Because distance between stator and cover was quite small, i chose to do a little little bit bigger first coils, and a little little bit smaller final coils. You can se that on measurment of level of resistance where, winding resistances aren't similar. But in next dimension we can see that resistances do not dramatically have an effect on on electric powered motors efficiency.
I made all exams with two different voltages. Engine was made for voltage 380V, but right now we have got 400V in EU.
In upper desk there is usually information from producer in very first series. In 2nd line is dimension at 380V and 3rd series at 400V. If we compare all data we can observe that motor isn't bad at all. All parameters are extremely close collectively.
I got all electrical equations and positioning furniture from book:Neven Srb ELEKTROMOTORI
I wish you enjoined my demonstration of rewinding a three phase engine. If you possess any queries please question, and i will test to remedy ass soon as probable. Thank you for your attention.
