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

open access: yesE3S Web of Conferences, 2023
To limit the inrush currents in the stator windings, various schemes for starting an asynchronous electric motor are used. In addition, the existing devices have a complex control system, which creates certain difficulties in installation and operation ...
