Abstract:
Electromagnetic starters are switching devices operating with electromagnetic actions that are designed to start and protect the electric motors of the excavator and drilling machines. Everyone knows that earlier electromagnetic starters have been used widely, but progress developments have shown that semiconductor elements are positive since these elements include self selectivity and reliability when starting and stopping electric motors during a voltage fluctuation or avalanche voltage. This article deals with the switching of electric motors of the EKG-8I excavator and safe control of electric machines during switching.
