The induction motor is the special kind of motor which runs below and above the synchronous speed. which the synchronous motor runs nearly equal the synchronous speed. The operation of synchronous motor runs with dc field excited hence separate dc field current is given to the field circuit. where as the induction motor the field and main field is drawn from the same supply hence no excitation is required. But due to this separate starting mechanism has to be required in case of the single phase induction motor.

Does the value of the exciting current of your 3-phase motor depend on the rotor speed?
An induction motor has no excitation, so the question is about a synchronous motor. The rotor speed is determined by the supply frequency. For a given supply frequency and mechanical load, the excitation current can be adjusted to give the best power factor.
Do you need starter for 0.5HP three phase induction motor?
You never need a starter for a three-phase motor.
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 excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
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.
Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.

Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
Do you need starter for 0.5HP three phase induction motor?
You never need a starter for a three-phase motor.
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
Is reluctance motor is a synchronous motor with dc excitation?
yes
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.
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
What is excitation of a DC motor?
DC Voltage
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
