This handy reference is intended for practicing electrical design engineers and technicians engaged in daily practical work. It contains several electrical values necessary for the design of control systems. It also includes essential basic fundamentals and the circuitry commonly encountered while designing control circuits. The book has been compiled bearing in mind safety aspects and international practice, as recommended by national and international agencies. Salient Features: Importance has been given to the three-phase induction motor (squirrel cage); Tables, fundamental principles and useful information on materials have been included. Brief descriptions of various types of motors and commonly encountered faults are given. A series of typical circuit diagrams are included along with a brief description of their working. Design guidelines for control cabinets, panels, etc. are given.An oscillator circuit excites transistors which alternately conduct through each leg of the main winding. ... This flux practically remains constant at all speeds of the motor giving rise to linear speed-torque and current-torque characteristics ... Current 2. AC Wound Rotor (Slip Ring) Induction Motor Characteristics similar to those of AC squirrel cage motors; the stator winding is stationary; the rotor windingsanbsp;...
