No, if anything motors need time delay fuses in the start up phase of their rotation. The motor will draw up to 300% of their full load amperage. Time delay fuses get the start up current past this phase of start up.
why three phase induction motor is delta connected
120 degrees
Yes the Induction motor works on Electromagnetic induction principle.
Polyphase is a general term that includes all electric power systems using three or more phases.
The three coils are actually called UVW. They are called that because they are for the three phases of a 415v supply.
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
AC Induction Motor
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
There doesn't have to be but capacitors are sometimes used to correct the power factor.

yes
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
