All the posts written about induction motor is useful for engineering students and the professional engineers working in the field. I tried to cover every practical aspects in the posts. Happy Readings !!!
Different Ways to Improve Starting Torque of A.C. Induction Motors
A.C. induction motor starting torque is very low as compared to DC motor starting torque. Also, during acceleration, the induction motor produces torque pulsation. As … Read more
Why do 3 phase induction motors not need a neutral?
3 Phase induction motor is a balanced three-phase load. Therefore, the induction motor draws a balanced current if the supply voltage and the impedance of … Read more
Why can’t an Induction Motor run at synchronous speed?
The induction motor can’t run at synchronous speed because it is not possible to run the motor without load. Even the motor is at no … Read more
What is the slip value of a 3-phase induction motor at synchronous speed and starting speed?
When the stator of the induction motor is fed three phase supply, the synchronous rotating field is generated. The flux generated in the stator gets … Read more
Change of Resistance in Wires by Stretching
We shall understand with an example how the resistance of a wire changes with stretching its length. Example-1 –Change of Electrical Resistance with wire stretching … Read more
Advantages and Disadvantages of Induction Motor
There are some of the advantages of induction motors compared to DC motors and synchronous motors. We will also discuss disadvantages of induction motors compared to … Read more
What is no load Current of Induction Motor?
The current drawn by the induction motor when it is not coupled to the driven equipment is called the no-load current of the motor. The … Read more
Why Three Phase Induction Motor Self-Starting?
When a three-phase supply is fed to the stator of an induction motor, the stator draws current from the 3-phase supply, which produces the magnetic … Read more
Dispersion Coefficient of Induction Motor
The power factor and dispersion coefficient of an induction motor have a relationship. The smaller the dispersion coefficient, the better the power factor. Power factor … Read more
