What is Form Factor? Form Factor Formula & its Derivation
What is Form Factor? Definition: The ratio of the root mean square value to the average value of an alternating quantity (current or voltage) is
What is Peak Value, Average Value and RMS Value?
Peak Value The sinusoidal waveform starts from zero, attains peak value, and again comes down to zero in a positive half cycle. In the next
Why Insulated Bearing is used for VFD driven Motor?
The insulated bearing for the motor is used to prevent the circulating current through the motor bearing. The circulating bearing current can damage the bearing.
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
