Inverter
- The system converts DC power from the batteries to AC power that is used to drive the motor
- A 3-phase PWM signal is sent to the motor to interpret the motor's resolver
- Silicon Carbide MOSFET’s were chosen due to great thermal conductivity, compact design, and lower heat generation
Heat Exchanger
- Traction inverter: enclosed cooling system with fans
- Motor: internal cooling system with released coolant along with a temperature sensor
- Batteries: water-cooling system
Resolver
- Analog device used to identify the angle of rotation of the motor
- Uses two fixed inductor coils positioned 90 degrees out of phase from each other
- Using the magnitude of these two outputs an exact position of the motor can be determined
mathematically which is used to then send current through the appropriate motor coils
Motor Mount
- Constructed with 80/20 components composed of 1/4-inch steel
- Capable of withstanding torque generated by the motor, support enough weight, and is easily maneuverable for testing.
