Frequently Asked Questions
what is the main difference between conventional moter and bldc motor?
Brush-Less Direct Current (BLDC) motor is a new technology that manipultes DC current using microcontrollers and MOSFET to create pwm signals in DC current thus modifying input signal of the coils in the motor. The pulse width modulation of the input signal is altered to increase and reduce the speed of the fan. BLDC technology uses permanent magnets to create a permanent magnet field for the fan. A conventional fan uses a simple capacitor and AC current to drive the motor of the fan. There are no permanent magnet or Printed Circuit board inside the fan. However the rotor of the fan is non magnetic and the magnet is induced in it when AC current is being run through the fan.
How can a BLDC motor consume less energy as compared to the conventional motor?
In a BLDC motor, we use printed circuit board (PCB) and permanent magnets. The board has two parts the first part convert AC current at 220 VAC 50 Hz to DC current. The second part uses microcontroller couple with MOSFETS to create customise signals in DC current instead of AC current at a very short distance is far more efficient as compared to AC current. Usually the DC current directly at the product supply reduces power losses. However, in case of AC power supply, AC power is best for transmission over long distances but they can be used to operate appliances as well. we require a capacitor to crudely modulate the ac signal for the motor, but through this inefficient process the losses are to high as compared to bidc technology.
Why does a BLDC fan / Hybrid Econopower / ACDC Inverter takes a jerk at the starting of the fan?
First of all, there is nothing to worry about regarding this jerk. In the bldc motor, we use segments of permanent magnets with opposing poles when the power is turned on these poles have to align with the poles on the stator this alignment of poles causes the fan to take realignment jerk before the fan Starts.
What re the advantages of BLDC motor overconventional motor?
There are many advantages of bldc technology over conventional motor. The most important one’s are as follows:
- The bldc technology is far more efficient as compared to conventional motor.
- The bldc technology, consequently, is far more energy conservative and environmentally friendly as compared to old conventional technology.
- The speed regulation of a conventional fan is far more difficult as compared to the speed regulation of a bldc fan. The speed dimmer coupled with the uninterrupted power supply (UPS) may cause humming noises on conventional fan. The bldc fans available in the market have remote controlled speeds. (Do not use fan dimmer or speed regulators for bldc technology).
- Conventional fan requires the voltage to be stable at 220VAC for it to work on optimum conditions however in case of bldc technology the switch mode power supply (SMPS) regulates a consistent output of power even if the input power is variable up to variation of +100V.
After paying different amount, can we replace ovr conventional fans with Hybrid Econopower fans?
No, the Difference in cost no way indicates that the two technologies are any way similar. Yes, if you wish to upgrade your fan from conventional fan to bldc fan we can buy your old fan back at a depreciated cost and the amount we owe you can be adjusted in the purchase of newer fan. This opportunity is for the existing customer of our brand only.
Can we use wi-fi to control the blidc fan in event that we lose are remote?
As of the end of 2023, the existing models of Lahore fan there is no wi-fi provision however in the future models we will be able to provide the customer with Wi-Fi option along with the remote option. Wi-Fi requires additional hardware which is going to be it costly as compared to the conventional RF remote but rest assured, the current RF remote of Lahore fans is for better than any existing remote in the market with longer range and prompt response.
How many watts are used by AC/DC inverter at 220VAC WAPDA AND 12 volt in the event of no WAPDA?
Power (Watts) = Voltage (Volts) x Current (Ampare) Our acdc inverter fan utilizes 55-60 Watts at top speed in any case. That means if volts are 200-240 VAC the ampares are 0.2-0.3A. However, in case of 12VDC, the ampares are 4.5-5 A.
Our fan has two power sources one is 220 VAC from WAPDA and other one is12 volt DC from solar power. Can the AC/DC inverter fan convert automatically on 12 volt or not?
Yes. The advanced microcontroller inside the printed circuit board of the fan has programming that identifies whether the WAPDA power supply is available or not. In case the WAPDA power is lost, the PCB switches to other power supply of DC source automatically..
