LESSON 1: VEHICLE OVERVIEW
•
Alternating current is supplied from the TIM to the motor through
high voltage cables.
– Current flows through the stator windings generating a
magnetic field.
– The magnetic field causes the rotor to spin.
– Varying the amount of current controls torque.
– Varying the AC current frequency controls speed.
– During deceleration and braking, a negative torque is produced,
and the motor acts as a generator and regenerates charge in the
traction battery.
