2. How do speed
control motors
work???

3. • PRINCIPLE OF SPEED CONTROL
• When the voltage applied
to the motor is increased
and decreased, the slip
(s) changes, then the
rotational speed (N) will
change.

4. SPEED CONTROL
TECHNOLOGY
- It is the controlling
and limiting of speed
with the use of speed
control motors and
devices.

5. Benefits of using Speed Control
Technology in the road
• Avoidance of Car Accidents
• Safe Driving in the road
• Preventing overspeeding of
vehicles
• Road Safety
• Helps passengers to cross in
the road

7. SPEED CONTROL
TECHNOLOGY
-Speed control motors
and devices are used to
control the speed of
pumps, fans, blowers,
vehicles, etc.

8. • Tacho-generator
- Is used to detect the
speed of the motor
• Potentiometer
- Is used for easy speed
control adjustment.

10. • Tacho-generator detects the
magnetic poles, and
generates an AC voltage at
12 cycles per revolution
• Since voltage and frequency
increase with a rise of the
rotational speed, the
rotational speed of the
motor is controlled based on
this signal

12. SPEED CONTROL
TECHNOLOGY
• Vehicles are equipped with a
speed control device that limits
the maximum speed by using
electromagnetic brakes in
combination with a motor once
the limit is exceeded.

13. • Speed control is one of
the most useful features
of the motor. By
controlling the speed of
the motor, you can vary
the speed of the motor
according to the
requirements and can get
the required operation.
