Abstract :
Performance equations on T- and L-connected tapped-winding capacitor motors with both the extra-main and the auxiliary windings arranged arbitrarily in space from the main winding are presented in this paper, using the revolving-field theory. Also shown is the fact that these general equations can be employed to yield performance on conventional T- and L-connected capacitor motors. By displacing the windings at locations other than conventional, it has been found that the motor effeciency increases considerably for both high and low-speed operations as well as the manufacturing cost goes down. The variations in the net torque developed and the efficiency as a result of changing the locations of the extra- main and/or the auxiliary winding are shown for the purposes of illustration.
