6.3.2. Motor Drives

Try these first

1. 1.

   Define motor drives in the context of electric vehicles.

   Hint

   Think about what controls motor functions in an electric vehicle.

2. 2.

   What do MOSFETs and IGBTs do?

   Hint

   Recall the names of common power semiconductor devices.

3. 3.

   What is the primary function of a motor drive in an electric vehicle?

   • To control the battery
   • To manage motor speed and torque
   • To recharge the battery

   Hint

   Think about what needs to be controlled in a motor.

4. 4.

   Regenerative braking captures energy during which process?

   • True
   • False

   Hint

   Consider where energy goes when a car slows down.

5. 5.

   Calculate the percentage increase in range if regenerative braking captures 10% of the energy that would normally be lost. Assume the original range is 300 miles.

   Hint

   Determine 10% of the original range and add it.

6. 6.

   Discuss how the effective control of speed and torque in motor drives could impact the user experience in electric vehicles compared to traditional combustion engines.

   Hint

   Consider how power delivery differs between electric and combustion engines.
