Abstract
This paper presents the methodology of Single Phase Induction Motor (SPIM) speed controlling by Multi frequency and new Binary Rate Multipliers (BRM) technique that gives rise to suitable energy supply to motor at any instant. Knowing the voltage and current, power is calculated by vector space method. The result is feedback to two Proportional-Integral (PI) controllers for processing by means of frequency 40 to 80 Hz and BRM which gives the patterns up to 256 forms. It shows fast time response of returning to normal state, both loading and no load, not exceed 1.0 seconds. The superiority of this technique is that, both apparent and reactive power decrease while running at no load and full load power factor increase up to 0.444 and 0.633 respectively. Thus, higher efficiency is achieved.
