2. Electromechanics focus on the interaction of electrical and mechanical systems as a
whole and how the two systems interact with each other.
This process is especially prominent in systems such as those of DC or AC rotating
electrical machines which can be designed and operated to generate power from a
mechanical process or used to power a mechanical effect.
Electromechanical devices are ones which have both electrical and mechanical processes. Strictly
speaking, a manually operated switch is an electromechanical component due to the mechanical
movement causing an electrical output.
ELECTROMECHANICAL SYSTEM USES AND PURPOSES
Electromechanical system is a system that integrates electronics, mechanics, pneumatic, hydraulics,
and computer control systems to create new & improved automated manufacturing production
systems

4. Are there significant differences
between different EV motors?

5. There are many types of motors but in that, there are 4 different types of motors
used widely and currently, most of the EVs manufacturers use:
Brushed DC Motor
Permanent Magnet Brushless DC Motor (BLDC)
Permanent Magnet Synchronous Motor (PMSM)
Axial Flux Ironless Permanent Magnet Motor

6. Types of
Electrical Motors.
THE ELECTRIC MOTORS ARE
AVAILABLE IN 3 MAIN SEGMENTS LIKE
AC MOTOR, DC MOTOR, AND SPECIAL
PURPOSE MOTORS.

7. DC MOTORS
MAY RUN FROM
96 TO 192
VOLTS
DC AC
MOTORS
AC MOTOR, THREE-PHASE
AC MOTOR RUNNING AT
240 VOLTS AC WITH A
300-VOLT BATTERY PACK.
A TYPICAL MOTOR WILL
BE IN THE 20,000 WATTS
TO THE 30,000-WATT
RANGE.

8. It is used by the Fiat Panda Elettra.
USAGE:
BRUSHED DC MOTOR
It gives the maximum torque at low speed.
ADVANTAGES:
Bulky structure Low efficiency
Heat generation at brushes
DISADVANTAGES:
A brushed DC motor is an internally commutated electric motor designed to be run from a direct
current power source and utilizing an electric brush for contact.

10. No rooter copper less
More efficiency than the induction motors
It is lighter
Smaller
Better heat dissipation
More reliable
Short constant power range
When speed increases torque decreases
Expensive
THIS TYPE OF MOTOR IS USED IN THE TOYOTA PRIUS (2005).
PERMANENT MAGNET BRUSHLESS DC MOTOR (BLDC)
ADVANTAGES:
DISADVANTAGES:
USAGE:

13. PERMANENT MAGNET SYNCHRONOUS MOTOR (PMSM)
PMS motors is the way in which the rotating magnetic fields in the rotor and the stator
are produced and interact. In synchronous permanent magnet motors, there is a native
rotating magnetic field, created by permanent magnets (hence the name of the motor)
in the rotor. The rotating magnetic fields of the rotor and stator in these motors are
locked and there is no slip.
The permanent magnets in the rotor are one of the key elements that increase the
power density and improve the efficiency of the motor. The increased power density
means high power in low volume.

14. More efficient.
Lower cooling needs
Gives high torque even at least speeds.
High production cost
Need for rare earth materials
Theoretical danger of demagnetization
Toyota Prius, Nissan Leaf, Soul EV.
the synchronous permanent magnet motor is the king of efficiency - it can reach
up to 94-95% and when there is only one motor in the car, then this is the type of
the motor used.
Advantages:
Disadvantages:
Usage:

15. No stator core
Weightless
More power density
Minimize copper loss
Good efficiency
Variable speed machines
Rotor is capable of being filtered to the lateral side of the wheel
