3. Content
1. Dc Series Motor .
2. Brushless Dc Motor (BLDC) .
3. Permanent Magnet Synchronous Motor
(PMSM) .
4. Three Phase Ac induction Motors .
5. 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
