Description

Abstract:

Within the past couple of years, advances in battery technology have led to the electric car revolution. Society is slowly shifting away from petroleum-powered vehicles and towards an all-electric standard. As such, two main components are now crucial to the development of these vehicles: batteries and electric motors. The latter is of particular interest as the technology has been vastly unchanged for quite some time. Delving into the world of electric motors, one finds that brushless DC motors and induction motors are the standard in industrial applications. However, these motors are not completely efficient at all RPM ranges. The torque output is highest at lower ranges of RPM and gradually decreases as the rotor spins faster and faster. This issue is due to hysteresis and eddy currents in induction motors. Brushless DC motors exhibit the same problems in addition to permanent magnets causing a decrease in torque efficiency. The aim of this project is to address these issues by creating a variable squirrel cage for induction motors and a variable magnetic field for brushless DC motors. This will in turn lead to more efficient electric motors as a whole.
