| Summary: | This thesis focuses on the fabrication of a prototype Low Power Motor (LPM) for indoor ventilation. The proposed motor consists of electromechanical system (actuator), spring, motion translator, position controller and proximity sensor. The principle of the LPM is based on the integration of the mechanisms of the solenoid actuator which produces linear motion further converted to rotational motion by using a motion translator. The motion translator consists of oscillating stator magnet and permanent magnet array. Power delivery is controlled by using the position control approach. With this prototype, the circulation or movement of air for indoor ventilation is suitable for rural dwellers. This is achieved by utilizing a limited power resource over an extended period of time. This research begins with a review of electromechanical system (actuators/motors) and permanent magnet arrays. Simulations of electromechanical system were performed by means of model developed in Matlab/Simulink environment. Experimental tests of the prototype were carried out to compare with simulation results. The developed prototype was tested on a commonly sized blade normally used for ventilation. It is able to produce a rotational speed of 350 rpm at 4.4 W of power, which should be sufficient for indoor ventilation and cooling of simple homes and buildings. |
