Measured efficiency improvements of induction motors with thyristor/triac controllers

Autor: Ewald F. Fuchs, W. J. Hanna

Publikováno v: IEEE Transactions on Energy Conversion. 17:437-444

The deployment of inexpensive thyristor/triac controllers improve the efficiency and do not increase the power factor of induction motors (as measured at the input of pole transformer) operating under variable torque and constant speed constraints. C
