The grounding conductor is sized to safely carry fault current for the short time until the breaker trips - it is also sized to keep the voltage drop due to fault currents in the ground below harmful levels. The motor wiring is sized to continuously carry the full load and to keep the voltage drop at full load during start-up within a few %.
