Types of Electrical Drives: Types of Electrical Drives has the following major parts: load, motor, power modulator, control unit and source. There are large number of loads and each load…
Starting Method of Induction Motor: Transient processes involved with the Starting Method of Induction Motor in a variable speed drive require a detailed study. The electric motor and connected load…
Characteristics of Synchronous Motor: Characteristics of Synchronous Motor are constant speed motors. The speed of the motor is decided by the number of poles and frequency. Compared to an induction…
Torque Speed Characteristics of Induction Motor: From Eq. 1.27 it can be observed that the maximum torque is independent of rotor resistance. However, the slip at which the maximum torque…
Pulse Modulation: Pulse modulation may be used to transmit analog information, such as continuous speech or data. It is a system in which continuous waveforms are sampled at regular intervals.…
Data Logger Summary: In general, a data logger is a comprehensive and highly advanced Data Logger Summary. It is made versatile and flexible, to render it suitable for widely varying…
Radio Frequency Modulation: Radio Frequency Modulation - The simplest method of measuring frequency deviation utilises an FM receiver with a BFO as the measuring instrument. The only coupling used is…
Vector Impedance Meter (Direct Reading): If some knowledge of the reactive and resistive factors is needed, in addition to obtaining a direct reading of the magnitude of the impedance (Z),…
