Σύνοψη

Advanced Motor Control Engineering introduces modern, new technology for controlling which employs methods and techniques having nothing to do with relays and generally with any mechanical logic devices, any more. Instead, power electronic devices are used. These are controlled by analogue or digital circuits which are either programmable or one function ci'rcuits. If programmable, personal computers perform their programming.
The scope of the present project it to introduce,
analyze and apply a method for the starting of three phase induction motors utilizing power electronics. The method is known as "SOFT STARTING OF AN INDUCTION MOTOR".
The primary emphasis in this project is given in designing and developing the control circuit used for driving the power circuit. Together with the representation of the various parts of the control circuit, a detailed analysis of those parts is provided.
The soft starting of an induction motor, is an advanced
method, which comes to substitute the previous methods where mechanical starters and relays were used. The new method is cheaper, its construction takes less space and it can be made to provide ways of protection of the motor, such as overload, phase failure. Also, the torque of the rotor and hence, of the shaft is increased smoothingly, eliminating sudden movements and large surges of current in the stator windings are avoided.
