Week 3 Session 7
Types of Motor Use in EV :
- Permanent Magnet Synchronous Motor(PMSM)
- Brushless DC Motor(BLDCM)
- AC Induction Motor(ACIM)
- Permanent Magnet Switched Reluctance Motor(PMSRM)
- Interior Permanent Magnet Motor(IPMM)
Brushless DC Motor(BLDCM)
Advantage
- It gives the maximum torque at low speed.
Disadvantages
- Bulky structure
- Low efficiency
- Heat generation at brushes
Usage
It is used by the Fiat Panda Elettra.
Permanent Magnet DC Motor :
Advantages
- No rooter copper less
- More efficiency than the induction motors
- It is lighter
- Smaller
- Better heat dissipation
- More reliable
Disadvantages
- Short constant power range
- When speed increases torque decreases
- Expensive
Usage
This type of motor is used in the Toyota Prius (2005).
Permanent Magnet Synchronous Motor(PMSM)
Advantages
- can be used without using gear systems in a different speed range
- More efficient
- Compact
- Best suitable for in-wheel application
- Gives high torque even at least speeds
Disadvantages
- During the in-wheel operation at high speed it losses the high amount of iron
Usage
Toyota Prius, Nissan Leaf, Soul EV
Permanent Magnet Switched Reluctance Motor(PMSRM)
Advantages
