What is effect of frequency on induction motor speed?
secret......... They are proportional..
What are different between induction motor and synchronous motor?
In an induction motor, the speed is dependent on applied voltage and can be varied as per requirement. In a synchronous motor, the speed depends on number of poles and frequency of supply. If frequency is constant, its speed will remain constant. Industrially...Induction motors are most preferred because of their robustness and efficiency
What is the effect of low voltage on induction motors?
The effect of low voltage on induction motors raises the current that the motor will draw.
Why the squirrel cage induction motor is one of the most reliable machines in industry?
because the squirrel cage induction motor is cheaper and high starting performance is not required.
How does induction motor start?
induction motor start by magnetic motor
What is effect of frequency on induction motor speed?
secret......... They are proportional..
How do the change in supply voltage and frequency affect the performance of a 3 phase induction motor?
Both of these two values have an effect on the revolutions per minute of the motor. It is these two values that the principal of the Variable Frequency Drive operates on. Not using a VFD, the nameplate ratings of the motor must be adhered to.
What is the Effect of reduced the frequency from supply frequency on induction motor?
The main difference will be the motor's torque will be decreased, potentially making it undersized for its' purpose. The motor's speed will also be decreased since n=(120f)/P.
How does a high frequency induction motor work?
In a high frequency induction motor, EMF is induced leading to current flow. Torque in the rotor coil increases. As frequency increases, Impedance of the Rotor increases and currency reduces.

How does induction motor start?
induction motor start by magnetic motor
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
What is the effect of induction motor on power factor?
An induction motor has a lagging power factor. Motors of more than about 2 HP are designed to have a power factor of 0.85 or higher.
What are the different methods to control the speed of a squirrel cage induction motor?
We can control the speed of the Induction Motor by 1)By changing Applied Voltage, 2) By changing the Applied Frequency, 3) By changing Number Of Stator Poles.
