Significant improvements in the performance of the triac voltage control of split-phase fan motors can be achieved by increasing the rotor resistance and winding ratio. These improvements include a reduction in the maximum main winding current and an increase in the speed stability throughout the control range. The analysis of the motor performance with(More)
Fan speed control of permanent capacitor run motors using triacs creates unbalance resulting from both amplitude and phase. The use of a force-commutation triac has greatly reduced this unbalance by advancing the fundamental of the main winding current at reduced speeds. The extra harmonics generated only slightly reduce the benefits of less unbalanced(More)
