What is BLDC technology? How is BLDC technology different from the older induction technology?

BLDC stands for Brush Less Direct Current. In this technology, the PCB (brain of the fan) converts AC current to DC current. As compared to an induction motor in which the stator and rotor both are made out of copper winding, in BLDC fans the rotor windings are replaced with permanent magnets. Hence, instead of the winding, these magnets are responsible for generating the electromagnetic field. Since, the magnet replaces the winding there is lesser power consumption and lower heat loss. This helps in saving energy consumption and electricity.

Since, the BLDC motor does not have any brushes between the winding there is lower friction/wear and tear. This results in longer life of the motor.

BLDC motors are used in electric vehicles and machine drives due to its efficiency & reliability.

Are BLDC fans noiseless?

As compared to an induction fan, the BLDC motor operations are significantly quieter. But any fan will always have air cutting sound. Thus, in comparison BLDC fans are noiseless but NOT noise free.

What is the benefit of BLDC technology?

BLDC technology has multiple benefits as compared to an induction fan.

  • Energy Saving: BLDC fans consume 26-35 W power as compared to induction fans that consume in the range of 55-75 W. This results in electricity consumption of 50-70% as compared to an induction fan.
  • Low noise Operation: BLDC fans have 5-10 dB lower noise as compared to an induction fan.
  • Consistent Performance even with fluctuating voltages: BLDC fans can operate smoothly even with fluctuating voltages. The speed of BLDC fans do not change when the voltage fluctuates whereas that is not the case for induction fans.
  • Convenient Operation: BLDC fans can also be operated by remote. Remote controlled operations can help you control your fan from anywhere in the room. The remote also has features like timer mode, boost mode, and fan scheduling.
  • Smart fans with IoT: Some of the BLDC fans are also IoT enabled. This means that these fans can be controlled via a mobile phone or can be paired with Google Home or Amazon Alexa to control via your voice.
  • Runs 2x longer on inverter: Since the BLDC fan consumes 50% lower power as compared to an induction fan, it runs 2x longer on inverter. This is very helpful in areas which have frequent power cuts.
  • Longer motor life: Since the rotor in BLDC motor is replaced by a magnet instead of winding, there are no brushes in this motor. This results in lower heat loss due to friction. Thus, the BLDC motor has higher longevity as compared to an induction fan.

How much electricity does BLDC motor save as compared to an induction motor?

A BLDC fan consumes 50% lower power as compared to an induction fan. A typical BLDC fan consumes 26-35 W power whereas an induction motor consumes 55-75 W power. BLDC fan consumes Rs. 1500-1700 lower electricity as compared to an induction fan.

Do BLDC fans operate with a remote?

Orient offers a wide range of BLDC fans. We have models that are operatable with remote and with regulator depending on your preferences. Remote models work only with remote, and to ensure proper functioning we would suggest you bypass the regulator during installation. Non-remote models (regulator-based models) work seamlessly with existing step regulators in the market.

Can BLDC fans be controlled with a regulator?

Yes, Orient offers a wide range of models that can be operated with a regulator. Models like I-Falcon, Hector 500, Ecotech Supreme, and I-Float have remote as well as regulator variants. You can choose either of them based on your preferences. Regulator models work seamless with existing step regulators in the market.

BLDC fans jerk when they start. Is this common?

Yes, this is a common occurrence. Fans work on the concept of electromagnetic force generated by the rotor (in this case magnet). It is very important that the stator (winding) and rotor (magnet) align correctly for the fan to function in any BLDC fan. The initial jerk is due to this alignment happening between the stator and rotor.

BLDC fan cannot be controlled with my regulator. Why does that happen?

If your BLDC fan is a remote variant, i.e. it can be controlled via a remote, you will not be able to control it with a regulator. During the installation of any remote fan, it is advised to bypass the regulator.

Do BLDC fans have a capacitor?

No, BLDC fans do not need a capacitor. The function of the capacitor is to give an initial torque to the fan. In a BLDC fan, that is done by the PCB (brain of the fan).

Are BLDC fans star rated?

Yes, the BLDC range of Orient is 5-Star rated as per Bureau of Energy Efficiency (BEE) norms.

Is the star rating of the BLDC fans certified?

Yes, all Orient BLDC fans are certified by the Bureau of Energy Efficiency (BEE). The proof of the certification can be found on the BEE stickers on any of our product boxes, and motor body.

Can I operate different ceiling fans with the same remote?

This depends from model to model. Multiple fans of models like Ecotech Prime, I-Falcon (Remote), Ecotech Supreme, I-Float IoT, Aeroquiet BLDC, and Aeroslim can be controlled with the same remote. For models like Hector 500 (Remote), I-Falcon Deco, Hector Deco, Jazz BLDC, and Wendy BLDC they have an option of controlling a single fan with a single remote or having multiple fans being controlled with the same remote.

What is boost mode?

Boost mode enables the highest speed of the fan, that is when you click the Boost option fan will then run on Speed 6 to give instant high air delivery. This is not possible in an induction fan.

I have heard that BLDC fans have lower air delivery as compared to normal ceiling fans. Is that so?

Orient BLDC fans have air delivery in the range of 220 – 260 CMM. This is at par with the induction fans. Due to lower noise, customers feel that there is lower air delivery but that is not the case. The lower noise is due to the BLDC motor and not lower air delivery.

My area has voltage fluctuations. Will a BLDC fan function properly in my area?

Yes. BLDC fans are deigned to sustain high voltage fluctuations. Orient BLDC fans give consistent performance even with voltage fluctuations. Remote operated models can sustain voltage fluctuations in the range of 120 – 280 V whereas regulator operated models can sustain voltage fluctuations in the range of 140 – 270 V.

This ensures that you get the best air delivery and comfort even with voltage fluctuations. On the other hand. An induction fan has varying speeds with different voltages.

My area has power cut issues. Will a BLDC fan work with generator?

Yes, Orient BLDC fans can work with any inverter. In fact, Orient BLDC fans give 2x run-time on inverters as compared to an induction fan. Since the BLDC fan consumes 50% lower power, it runs 2x longer on inverter.

My fan is making a noise. What can be the reason behind it?

The noise in a fan can be of multiple types.

  • Whooshing sound: This sound is usually produced due to air cutting. Since the blades of the fan cut the air, they tend to produce this sound. This sound is normal during operation of the fan.
  • Tik-Tik noise: This noise can be due to improper installation. An easy way to get this corrected is to get it tested by an Orient service professional and get it re-installed.
  • Scratching sound: This noise is usually made when there is dust accumulation on the bearing or the bearing gets old. The solution for this is to get the fan un-installed for cleaning and greasing of the bearings.
