Induction motor operated with pole amplitude modulation technique is
to give two speeds or more. The motor parameters are modified for each
speed. These parameters are function of the motor number of poles,
number of stator series turns per phase, stator winding factor and type of
operation.
The parameters of a tested motor are calculated taking into account the
above factors at two speeds 1500 & 3000 r.p.m. The performance
characteristics of the motor are calculated based on the equivalent circuit
and compared with experimental results.
