Abstract

Shaded Poles Motors and Single-Phase Capacitor Induction Motors are the most common low cost solutions for household appliances. Alternative high efficiency motors are the Electronically Controlled (with or without Permanent Magnet) Motors. This paper proposes a fractional Permanent Magnet Brushless DC Motor (PM BLDCM) with exterior-rotor and concentrated winding for variable-speed fan (domestic hood). It fulfils all the main application constraints (low torque ripple in order to reduce noise and vibration, efficiency, simple structure, robustness, small size). Comparisons between simulation and experimental results confirm the goodness of the proposed design procedure. In comparison with the line fed Single-Phase Capacitor Induction Motors, the experimental results show that the PM BLDCM drive is a suitable high efficiency solution for household appliances such as domestic hoods.
