Abstract
The transportation sector is the biggest consumer of gasoline and always increase in every year. Electric vehicle (EV) is an effort to reduce fossil energy usage. The electric vehicle being developed is a Golf cart. Golf cart EV uses the electric motor as its driving force. Types of electric motor often used is an induction motor. This research aims to design a low-voltage induction motor as the propulsion force with desired performance and operating characteristics. The design process uses ANSYS Maxwell RMxprt simulation software. The design proposed for Golf Cart EV uses three phases, 48V induction motor, with phase frequency of 50 Hz, output power of 3HP, and is using class C NEMA design. The design process is done by firstly determining the specifications of the motor, then calculating the main dimensions, windings, as well as the stator and rotor slots. When operating in its rated voltage, the induction motor has efficiency, power factor, and slip values consecutively are 86.07%, 0.82, and 3.62%. Motor characteristics can be seen from locked rotor torque, locked rotor current and breakdown torque from induction motor design information whose values consecutively are 222%, 605%, 308% of the rated value.
