Torque Slip Characteristics Of Induction Motor
Torque slip characteristics of induction motor show detailed information about torque and slip. There are three operating zones of induction motor. We shall discuss these
Induction Motor
Cogging and Crawling of Induction Motor
What is Cogging and Crawling? The phenomenon of cogging and crawling of the induction motor happens due to improper motor design or operation by feeding the
Effect of Unbalanced Voltage on Induction Motor
The induction motor is most vulnerable if the voltage is higher or lower than its rated voltage. The performance of the motor depends on the
Dynamic Braking in Variable frequency Drives
Dynamic braking is the method of stopping the motor by dissipation of heat in the resistor. When VFD drives a motor, the motor acts as
Effects Of Harmonics in Induction Motor
Harmonics in induction motors adversely affects motor performance, leading to temperature rise and increased losses, decreased torque, and noise problems. Due to simplicity in construction
VVVF Drive- Why V/f Ratio is Kept Constant in VFD?
VVVF( Variable voltage variable frequency) control is used to control the speed of the induction motor. The VVVF drive controls the voltage and frequency simultaneously
