The windings of an AC motor are called?
Windings
How are start windings placed with the run windings?
yes
What song by W.C. Handy is known as "the jazzman's hamlet"?
St. Louis Blues
What are the types of winds?
Local wind and Global wind
What is the three phase transformer?
it has three primary windings & three secondary windings.
What is the difference between lap windings and wave windings?
Lap windings has four current paths, the same as the number of the field poles, while the Wave windings has only two paths, regardless of the number of poles. Lap windings are also used for applications requiring lower voltages at higher currents, while Wave windings are used for applications requiring higher voltages at lower currents
What are start and run windings of a motor?
Start winding determines the direction of rotation. Start windings are considered "secondary windings" and run windings "primary". Usually, the start windings disconnect from the power circuit and dry film capacitor(s) at about 75% of the motors full speed. There are some motors with oil filled capacitors that keep the secondary "start" windings in the power circuit but only disconnect the dry film caps. The primary "run" windings are always in the power circuit. There are more, could write a couple of pages on the whole workings.
Which type of winding use in power transformer?
The transformation ration for a transformer is (Vs/Vp) = (Ns/Np).Which means, Voltage ∞ No. of turns.So, we can say if we have to increase voltage, then we have to increase the no. of turns, and as the no. of turns increase the space between the core and the winding reduce.So, from above we can say that the HV windings are closer to the core than the LV windings.AnswerThere are two configurations for windings in transformers.The first is called 'concentric' or 'tubular', in which the low-voltage windings are placed innermost (i.e. closest to the core) with the high-voltage windings outermost.The second is called 'sandwich', in which the windings are arranged in ring bundles, with alternate rings of high- and low-voltage windings placed one above the other.The first configuration is used with 'core' type cores, with half the LV/HV windings placed around one limb of the core, and the other half of the windings placed around the second limb. The second configuration is used with 'shell' type cores, with the ring bundles placed around the centre limb.
Why would you megaohm a motor?
To determine whether there are any electrical shorts among windings, or from windings to case ground.
