Capacitor Optimization of the Single-Phase Capacitor-Run Induction Motor

Abstract:

Capacitor matching in single-phase capacitor-run induction motor (SPCRIM) is investigated in this paper. Combining symmetrical components method with resultant current method, capacitor value is calculated. Relationship between turn ratio of main winding and auxiliary winding, main winding current, auxiliary winding current and capacitor value is analyzed by simulation. SPCRIM is optimized on the ground of the theoretically calculated capacitor value and turn ratio of the main and auxiliary windings with FEA (Finite Element Analysis). Results show that calculated capacitor value contributes to the determination of turn ratio of the main winding and auxiliary winding, and with appropriately calculated capacitor value and turn ratio, small winding current can be got.
