What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Application of induction motor in industry?
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
What type of induction motor used in ceilinf fan?
Could be a single phase induction motor of 20-40 watts.
What type of induction motor is used in table fan?
Motor used in Table Fan is Split phase Motor(Continuous Running with Capacitor).It has Two winding Running coil + Starting Coil. Running coil connected Direct to Supply Starting coil Connected is series with capacitor than parallel with power.
Is a three phase induction motor self starting?
A three-phase motor has a steady rotating magnetic field generated by the stator coil, and the rotor just follows the field.
How does a generator use electromagnetic induction?
A generator uses electromagnetic induction by moving a coil of wire through a magnetic field. As the coil moves, it cuts through the magnetic field lines, inducing a current in the coil according to Faraday's law of electromagnetic induction. This current is then transferred out as electrical energy.
Why wattmeter shows negative reading during no load condition of 3phase ac induction motor?
no load means the motor is acting like a coil
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Which device transfers electrical energy from a primary coil to a secondary coil induction?
A transformer is a device that transfers electrical energy from a primary coil to a secondary coil through electromagnetic induction. It functions based on the principle of Faraday's Law of electromagnetic induction.
Applications of 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.
What is a decripition of Nikola Tesla induction electric motor?
AC Induction Motor
How relay is used to control induction motor?
If you want to control induction motor using a control relay give neutral directly to the one point of coil of relay & one point of coil of contactor then give control supply through push button to second point of coil of relay. use one NO point of relay and give supply to coil of contactor. and also use one NO of contactor for holding the contactor & take OFF (NC) in the starting to stop motor after complition of work. It is jut like an Direct On-line starter.
Difference between transformer and induction motor?
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.
Can a Squirrel Cage Induction motor can be converted to Slip Ring Induction Motor?
yes
