Development of contactless switching devices for asynchronous machines in order to save energy and resources

To limit the inrush currents in stator windings, various schemes for starting an asynchronous electric motor are used. In addition, existing devices have a complex control system, which creates certain difficulties installation and operation. But analysis of scientific literature materials from sources testifies to insufficient study this problem. work, advantages disadvantages new type contactless starter compared with contact non-contact starters types. An original circuit thyristor simplified design has been developed manufactured, ability smoothly start power consumption machines. Computer simulation pulse-width modulation Matlab Simulink program carried out: pulse current is supplied controlled electrode on basis opens passes current, resistance set decrease input signal level. The proposed based combination logical control, remote motors, save energy resources. Modern methods implementing generator RLC filters, proposed, task monitoring asynchronouselectricmotors set.
