Soft starter and soft stopping for speed control for induction motors
Introduction
The project is entirely on the design and development of a soft starter converter that will satisfy and implement the soft starting and soft stopping for speed control of an induction motor. Soft starters also called solid state starter are used for gentle starting and stopping of induction motors. Pumps, centrifuges, compressors, escalators, belt conveyors, mills, fans, stone crusher and saws are typical applications. If a motor is not adequately protected the sudden change in rotation torque and speed, which occurs on starting and stopping will jolt the equipment linked to it. Over the long term this can lead to increase in mechanical wear of gearboxes, clutches, transmission and conveyor systems. Abrupt starting and stopping can also damage goods being handled by the mechanical equipment. For instance, the filling and distribution of glass bottles and containers loaded on to a conveyor holds a potential for a minor disaster. One sudden jerk during starting and stopping will surely cause the entire process line to engage in a mass of broken glasses and dripping liquids or sticky product. With pumps soft starters eliminate pressure shocks in pipes and valves when the pipe pump starts or stops. This poses a particular safety hazard when the transfer of volatile and/or inflammable liquid is involved.
Background Information
Soft starter controllers provide the soft starting and stopping of induction motors with no beyond high maximum currents, motor heating or mechanical shocks. However this is more vital for most of large machines because there is entirely reduced starting torque and reduced impacts on mechanical parts, however this result in an increase in the equipment lifespan. Also the soft starting and soft stopping result in mass energy saving the power supply since the starting currents and voltages are low, meaning the amount of power dissipated at the start is
