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…
Transient Response of Closed Loop Drive System: The Transient Response of Closed Loop Drive System is of fundamental importance and must be investigated in detail. The time response of a…
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…
Chopper Fed DC Drives: The variable voltage to the armature of a dc motor for speed control can be obtained from a dc chopper which is a single stage dc…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter…
Single Phase DC Series Motor Drives: In the Single Phase DC Series Motor Drives the field is connected in series with the armature. The field current is the same as…
