Ward-Leonard Motor Generation System Introduction: A control system generally controls‚ regulates‚ and updates its output continuously based on present inputs‚ nature of the system‚ and the past outputs. In other words‚ there is a feedback mechanism that is inherent in the system‚ and is called a closed loop control system. For example‚ adding an emitter resistance to a common emitter amplifier‚ results in a negative feedback mechanism in the amplifier system – if the output current increases

Chapter (9) Single-Phase Motors Introduction As the name suggests‚ these motors are used on single-phase supply. Singlephase motors are the most familiar of all electric motors because they are extensively used in home appliances‚ shops‚ offices etc. It is true that singlephase motors are less efficient substitute for 3-phase motors but 3-phase power is normally not available except in large commercial and industrial establishments. Since electric power was originally generated and distributed
