Design of an Axial Flux Permanent Magnet Synchronous Motor for a Pedestal Electric Fan Application

Electrical energy is very important todays. In summer season, the use of the electric fans is increasing which will increase the electricity consumption. By using high efficiency electrical devices, the electricity consumption and the electricity bill will be reduced. An electric fan is a common household appliance whose main component is an electric motor. Generally, the electric motor used in the electric fans is an induction motor. To support energy conservation in terms of saving the electrical energy, it is important to use a high efficiency electric motor. The axial flux permanent magnet motor is proven to be a high performance electric motor which can be applied in various fields. In this study, a single-side axial flux permanent-magnet motor is designed to be used as a main component for a pedestal electric fan. The finite element method from the Ansys Maxwell-3D software is used to obtain the motor performances at 900 rpm, 1200 rpm and 1400 rpm. From the results, the developed average torque at 900 rpm is 0.1742 Nm, at 1200 rpm is 0.1730 Nm and at 1400 rpm is 0.1723 Nm. In term of the efficiency, the motor is better operated always at 1400 rpm, often at 1200 rpm and rarely at 900 rpm.
