What are the advantages of open end winding induction motor over conventional induction motor?
Open ended induction motor - i assume you are talking about split phase induction motor. With these motors old style speed controlling method using external resistors can be used. However this is now obsolete.
Can induction motor start at no load?
yes
How many poles are required on motor starters for the following motors a240-volt single-phase induction motor b440-volt three-phase induction motor?
For a 240-volt single-phase induction motor, a two-pole motor starter is typically required, as it connects to the two live conductors of the single-phase supply. For a 440-volt three-phase induction motor, a three-pole motor starter is needed, as it connects to the three phases of the three-phase supply.
What is a CSIR motor?
A CSIR motor stands for Capacitor Start-Induction Run motor, which is a type of single-phase induction motor commonly used in household appliances like refrigerators and air conditioners. It uses a capacitor to provide the starting torque needed to initiate rotation, then operates as a standard induction motor once up to speed.
What type of motor is used in table fan?
Table fans typically use an AC induction motor, which is cost-effective, efficient, and reliable for driving the fan blades. The motor is designed to provide the necessary torque and speed for the fan to effectively circulate air in a small space.
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
Does a induction motor need excitation?
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.

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
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
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.
Disadvantages of a squirrel cage motor?
Squirrel Cage Induction Motor Disadvantages:Some of disadvantages or demerits of squirrel cage induction motors are listed below:Main disadvantage of squirrel cage induction motor is that they have poor starting torque and high starting currents. Starting torque will be in the order of 1.5 to 2 times the full load torque and starting current is as high as 5 to 9 times the full load current. In slip ring induction motors, higher starting torque can be attained by providing an external resistance in the rotor circuits during starting of the slip-ring induction motor. This arrangement in slip-ring induction motors also reduces the high inrush currents during starting of induction motor.Squirrel cage induction motors are more sensitive to the supply voltage fluctuations. When the supply voltage is reduced, induction motor draws more current. During voltage surges, increase in voltage saturates themagnetic components of the squirrel cage induction motor.Speed control is not possible in squirrel cage induction motor. This is one of the major diadvantages of squirrel cage induction motors.The total energy loss during starting of squirrel cage motor is more compared to slip ring motors. This point is significant if the application involves frequent starting
What type of motor is used in ceiling fan?
single-phase induction motor is used in ceiling fan.
