5. Limitations of induction / Conventional
Ceiling Fan
Present Conventional Ceiling fan manufacturing
technology is Induction Motor Base
• Loss /current consumption is comparatively very
High,
• Speed unexpectedly vary with change of operation
voltage
• Loss is always same where as speed is vary with
regulator / voltage .
• Two Coils (Starting & Running)
• Harmful when the IPS is used
• Motor temperature may rise up at the time of operation
• Difficult to use remote control system

6. DC Fan
• Size : 1200 / 1600 mm
• Speed : 320 – 350 RPM
• Air Delivery : 231 m³/min
• Watt Loss : 08 - 36 W (Max)
• Speed control : PWM / Remote Control
• Power Factor : N/A (Because DC)
• Frequency : N/A
• Input Voltage : 240 V
• Operating Volt : 132 – 260 V

7. Benefits of Power Saving Ceiling Fan
My Power Saving Ceiling fan manufacturing
technology is DC Motor Base
• 36W power consumption (Where Conventional
fan –> 75-120W)
• Very easy to get five star mark from BSTI.
• Remote control.
• We can use as Silent alarm.
• Smart mode (time vs speed control).
• Also Controller by Mobile Apps (optional) (most
opportunity for business to earn permanently)
• Long lasting.
• No speed variation due to voltage variation.

8. Benefits of Power Saving Ceiling Fan
• Power consumption will be reduced with speed
decrease where conventional fan doesn't ( at
Lower speed – 8 W, at mid speed - 24 W and
High Speed - 35 W)
• Also use with Battery as well as solar system
(optional).
• Noiseless.
• No heating increase.
• Night Mode Light facilities can be added
(Optional)
• No need capacitor and regulator.
• High torque and speed – Max 350 RPM (Where
Conventional fan –> 290-320 RPM)

9. Benefits of Power Saving Ceiling Fan
• Time setting facility is available
• Smart looking
• Optimized weight
• Reduce the carbon footprint which very good
for health
• Loss will lower where as speed is lower .
• Only one Coil (Running)
• No problem when the IPS is used
• Motor temperature will not rise up too much
• Very Each to use remote control system

12. Benefits as 1st technology Power
Saving Ceiling Fan - (Next Target)
My Power Saving Ceiling fan Convert
technology is DC Motor Base
• Reuse the Armature
• Re-cycle of Body, Blade, Copper, Plastic
Canopy
• Scrape Sell – Rod, Rotor,
*** Replace Conventional fan with new power
saving fan for 2000 BDT where old fan price may
consider only 1500 BDT or less as brand and raw
materials.

Note:
1. So the price of fan will be cover with electric bill within 3 or 4 years.
2. 0.596 kilograms of CO2 are currently produced for each kilowatt hour of electricity generated.

14. Household in Bangladesh – 35,200,000 Nos according to 2021 Statistic so minimum Number of
fan more than 35,200,000 Nos Which need to convert
• As Existing New Market as continue for
conventional Ceiling Fan
• Have to make plan to convert all existing fan
to energy/power saving fan with average
profit but high quantity.
