Main Fundamentals of Electronic Matching

It is important to state that the firing angle that each thyristor pair counts is controlled electronically in order to apply a variable voltage to the motor terminals during the acceleration process. At the end of the starting period, normally adjustable on average, between 2 and 30 seconds, the voltage can reach its full value […]

Three Phase Electric Motors

Approximately in the year 1889, was invented by the Russian electrical engineer Dobrowolsky the first three-phase electric machine, with 80 watts of power and yield of approximately 80%. The device could be considered as an ideal component for use in the industry, because it presents satisfactory performance, effective starting and operation process without noises or […]
