The article describes the history of 50 years of research on eddy current starters conducted at the Faculty of Electrical Engineering of the Wrocław University of Science and Technology. Descriptions of the construction of the developed eddycurrent starters are presented. The significant advantages of eddy current starters are: simple structure, small dimensions, low production costs, high operational reliability, no moving parts and no coolant, no need for service and maintenance. The eddy-current starters can be operated as the rotor starters at the connection to the slip-ring induction motor or as the stator starters at connection to the stator terminals of squirrel-cage induction motor or to the armature terminals of synchronous motor. As a result, the advantageous stepless waveforms of the starting torque of the motor are obtained and the value of the starting current of the motor is reduced. The composition of research team for studies of eddy-current starters was presented. The profiles of the main participants of the research team were described and the topics of their research were given. The developed Ph.D. thesis, scientific articles, technical reports and patents were mentioned. The most important industrial implementations of eddy-currents are listed and discussed.
