Influence of Voltage System-Level to the dimensions and performance of Squirrel Cage Induction Motor Three Phase 50Hz 5HP for Electric Vehicles

The transport industry is Indonesia's largest consumer of fossil energy. Electric vehicle (EV) is an attempt to decrease the use of fossil fuels. Types of electric motor often used is an induction motor. In this paper, the parameter design and performance of squirrel cage induction motor 5 HP for EVs are investigated by changing the voltage system, 48 V for low voltage system and 360 V for high voltage system. The design process is performed using simulation software. With the same design factor, main dimensions of two voltage system designs have same size. The different design located on stator winding and slot. In stator winding, wire gauge diameter and number conductors per slot are different. In stator slot, low voltage system needs a wider slot than the higher voltage system. The performance from ANSYS Maxwell simulation of high-voltage and low-voltage induction motor three-phase frequency 50 Hz output 5 HP for golf cart electric vehicles voltage system does not have a significant difference. The two design have efficiency, power factor, rated torque and slip about 87%, 0.93, 24.5 Nm and 3%.
