Types of electric motors in electric vehicle

1. DR :AHMED SAMIR MTE E0962 Abdelrahman tag Types of electric motors in electric vehicle

2. ELECTRIC VEHICLE

3. Content Dc Series Motor . Brushless Dc Motor (BLDC) . Permanent Magnet Synchronous Motor (PMSM) . Three Phase Ac induction Motors . Switched Reluctance Motor (SRM) .

4. DC SERIES MOTOR DC BRUSHED MOTOR DC ELECTRIC POWER IS SUPPLIED B / W ONE END OF SERIES FIELD WINDINGS & ONE END OF ARMATURE

5. DC SERIES MOTOR DC BRUSHED MOTOR DC ELECTRIC POWER IS SUPPLIED B / W ONE END OF SERIES FIELD WINDINGS & ONE END OF ARMATURE

6. Adventages & disadventages Adventages EASY SPEED CONTROL * HANDLE INCREASE IN LOAD Disadventages HIGH MAINTENANCE BRUSHES & COMMUTATORS

7. Used in trains

8. BRUSHLESS DC MOTOR ( BLDC ) PERMANENT MAGNETS ARE USED Rotor THEY DO NOT HAVE BRUSHES COMMUTATION IS DONE ELECTRONICALLY

9. Adventages & disadventages Adventages LOW MAINTENANCE HIGH STARTING TORQUE HIGH EFFICIENCY Disadventages HIGH COST OF PERMANENT MAGNETS HIGH HEAT WEAKENS MAGNETS

10. Used in light weight . Kinetic green speego

11. PERMANENT MAGNET SYNCHRONOUS MOTOR ( PMSM ). AC SYNCHRONOUS MOTOR . FIELD EXCITATION IS PROVIDED BY PERMANENT MAGNETS ON ROTOR .

12. Adventages & disadventages Adventages HIGH POWER DENSITY HIGH EFFICIENCY Disadventages High cost

13. Used in hybrid & electric cars . TOYOTA PRIUS . NISSAN LEAF .

14. THREE PHASE AC INDUCTION MOTORS . PRINCIPLE OF ELECTROMAGNETIC INDUCTION 3 PHASE SUPPLY , A ROTATING MAGNETIC FIELD IS SET UP WHICH ROTATES AROUND STATOR AT SYNCHRONOUS SPEED

15. Adventages & disadventages Adventages SELF STARTING ROBUST & WITHSTAND TOUGH ENVIRONMENT LOW COST . Disadventages POWER FACTOR IS LOW DURING LIGHT LOAD .

16. USED IN TESL MODEL S

17. SWITCHED RELUCTANCE MOTOR ( SRM ) . VARIABLE RELUCTANCE MOTOR ROTOR ALWAYS TRIES TO ALIGN ALONG THE LOWEST RELUCTANCE PATH SWITCHING INVERTER IS USED FOR THIS OPERATION

18. Adventages & disadventages Adventages * SELF - STARTING STARTING TORQUE IS HIGH HIGH TORQUE / INERTIA RATIO disadventages COMPLEXITY IN CONTROL NOISE LEVEL IS HIGH

19. USED IN INTERNAL PERMANENT MAGNET SYNCHRONOUS RELUCTANCE MOTOR ( IPM - SYNRM ) . TESLA MODEL 3

20. DEPENDING ON THE REQUIREMENT THE MOTOR TYPE IS SELECTED and USED IN ELECTRIC VEHICLES
