This paper discusses loss minimization in the vector-controlled induction motor from
the point of view of a two phase induction motor. A vector-controlled drive with loss minimization
function was developed and evaluated for step changes in load torque ranging from full load to quarter
load. A loss minimization scheme based on motor core loss resistance was formulated and integrated
into the vector control scheme in which the rotor flux magnitude is aligned to the synchronously
rotating direct axis component. The objective of the scheme is to regulate the motor flux such that
minimum losses occur for any load torque applied on the motor. The performance of the developed
system is carefully examined and compared to the performance of a conventional vector-controlled
two phase induction motor drive which operates at rated flux regardless of changes in load torque.
Simulation results demonstrate significant reduction in power losses for light loads applied to the
induction motor under the proposed drive scheme. Specifically, it was observed that the reductions in
loss levels are 17.5%, 52% and 75% for full load, half load and quarter loads respectively with respect
to the loss levels in the same motor under the conventional drive scheme.
Keywords: Losses; minimization; induction motor; two phase; vector control.
