Abstract:
The dissertation deals with the performance-prediction of the single-phase Induction motor with two asymmetrical
stator* windings not in space quadrature, -taking into account the effect of space-harmonies. Crossfield theory in a generaz.sod form has been applied as dealt
in reference with a modification* A transformer analogue
analyser type equiva.ent circuit is also developed. The
m ,chine is shown to be equivalent to a machine with two at .i t or-winding s in space quadrature for full, i load ru~rning
(i.e. near synchronous spe ds) and a simpler and handy equivalent circuit is determined, neglecting the space*» harmonics iitthout 'pprec.able error.
The performance of a single phase induction motor bei
having non#quadrature stator-windings has boon analysed$ with
stress on start4.ng torque torque, starting-
c p:,citor requirr3nt, suppression or reduc4ion of asynchronous dips in the torque-speed characteristic, running and
plugging op3rations
