Polar Plot for Frequency Response: One of them is the Polar Plot for Frequency Response representation. The transfer function in the frequency domain is obtained by substituting jω for s…
Periodic Intermittent Duty: The class of duty making use of the ability of electric motors to operate with overload is called Periodic Intermittent Duty. The load on the motor is…
Short Time Intermittent Duty: Another class of duty for normally occurring loads is Short Time Intermittent Duty in which the load requires a constant power for a short interval of…
Continuous Duty Motor: There are two types of Continuous Duty Motor — continuous duty at constant load and continuous duty with variable load cycle. In the former the load torque remains…
Electric Motor Cooling and Heating: The geometry of an Electric Motor Cooling is too complex to predict accurately the heat flow and temperature distribution. This is a difficult task. A…
Synchronous Speed on Variable Frequency Supply: As has already been discussed, the speed of a synchronous motor can be varied by supply frequency variation similar to an induction motor. The…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
Square Wave Voltage Source Inverter Fed Induction Motor Drive: Square Wave Voltage Source Inverter Fed Induction Motor Drive is a kind of dc link converter, which is a two stage…
