Abstract :
For economical reasons and to eliminate the DC motor´s mechanical commutator, the first kilns are now in operation driven by robust squirrel cage AC motors which are fed from PWM inverters. After discussion of design considerations and criteria, the basic circuits and data of the first two AC kiln drives, one single and one double drive, are presented. Each of the two kilns has over one year of operational experience
