If the windings weren't insulated then there would be no reason for the current to go all the way through the wires. It would just go staright across from one terminal to the other.

How do i know that they have electromagnet in the motor?
because it will contain a magnet inside that spins with copper windings like a car alternator
The windings of an AC motor are called?
Windings
What happend when you start motor without starter?
The windings of the motor will be gonebecause of high current diectly goes to the windings of motor.
How high can a transformer be rated?
The limiting feature of a transformer is the thermal breakdown of the insulating varnish on the wire. Once this breaks down, some of the windings will short circuit, which will lead to rapid breakdown of the transformer. For small high voltage transformers, the windings are carefully laid down with insulating foils between adjacent windings so as to limit dielectric breakdown.
How Synchronous motor work with principal?
A synchronous motor comprises of a stator windings and a rotor with a squirrel cage and inside that is windings(coils). At starting, this motor is an induction motor running with slip. After the rotor has reached a certain speed, a DC current is applied to the windings inside the squirrel cage. A fixed field is induced in these windings. This field locks in with the synchronous rotating magnetic flux of the stator windings. The rotating stator windings then pull the rotor along. The amount of excitation current can be used to control the power factor of the motor, making this a popular type of motor for high power use with a constant mechanical load.
Why alternator space heater used?
Alternators windings do not carry any current when it is not in motion. In high humid environment, the moisture ingress in the windings can reduce the resistance between the winding conductor and the body. When a moist alternator is started, the alternator windings may burn due to short circuit with body. To avoid this, the winding can always be kept warm by using heaters called "space heaters".
What is the function of the overload protector?
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.
What is the function of overload protector in refrigerator?
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.
Where is the alternator stator found?
Lines inside of case, big ring of copper windings
What is interpole winding in DC machine?
For a D.C motor it is the field windings which must always be in series with the armature windings.
Why would you megaohm a motor?
To determine whether there are any electrical shorts among windings, or from windings to case ground.
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
