Text: The ZXBM1004 and ZXBM2004 devices are both variable speed fan motor pre-drivers. This concludes the explanation regarding the making of a simple BLDC ceiling fan circuit, if you have any related doubts let me know through your valuable comments.Formula for fan motor winding Datasheets Context Search Catalog DatasheetĪbstract: Formula for fan motor winding 24V FAN CONTROL BY USING THERMISTOR 2-phase hall effect driver hybrid motor driver 2-Phase Motor hall 2-phase fan motor driver AN43 ZXBM1004 ZXBM2004 However it must be noted that motors rated with higher voltage will give higher efficiency for this particular application. You can use any BLDC for that matter, and power the DC circuit and the motor with an SMPS. The main objective of using a BLDC fan is to implement a capacitor less motor (or brushless motor) where the rotor does not carry any winding, which in turn ensures virtually zero friction and therefore extremely high efficiency compared to the normal capacitor type ceiling fan units. Here the secondary winding ratio could be suitably doubled for getting the required 24V instead of the specified 12V in the design.įor the 5V supply you can use a 7805 IC based stage, and achieve the 5V requirement for the BLDC controller card. In case you decide building the SMPS yourself, you could perhaps try the concept explained in this 12V, 2 amp SMPS circuit. Parts Listįrom the above shown BLDC ceiling fan controller circuit, we can understand that the circuit will require a DC power for operating, and this may be fulfilled through any standard SMPS unit, the best example being your laptop charger which can be effectively used for operating the proposed 24V BLDC motor, through the given controller circuit. The 10K pot serves as the speed control knob for the ceiling fan. The diagram looks pretty straightforward, and you just need to connect the parts as displayed in the diagram, using a well designed PCB. To control this motor and apply it like a ceiling fan, we can use the 50V driver circuit link as indicated in the previous paragraph, and modify the attached diagram to suit the ceiling fan control parameters, as indicated below: Circuit Diagram Let's assume we select a 24V 2 Amp BLDC for our ceiling fan, as shown in the following example, make sure it includes sensors with it: Since acquiring a 24V BLDC motor appears to be much easier than a 220V counterpart due to its easy availability in the market, we'll discus the proposed BLDC ceiling fan circuit using a 24V BLDC motor. On the other hand if a lower rated BLDC motor in the range of 12V to 50V looks easier to obtain, one could think of selecting the following alternative design, which was also posted recently in this website: The BLDC controller specs can be selected as per the available BLDC motor's specs, for example if you find it comfortable procuring a 220V or 310V BLDC you could probably go for a controller design having matching specs, such as the following circuit which was posted sometime back in this website.Ĭompact 3-Phase IGBT Driver IC STGIPN3H60 To achieve this, you may have to acquire or make the following modules:Ģ) An SMPS for powering the BLDC controller circuitĤ) propeller or blade fitting for the motor. In fact making a BLDC based ceiling fan circuit may be much easier than a capacitor-start type of fan, and could be done by even by an ordinary hobbyist having basic knowledge of electronics. Just as the traditional incandescent lamps today are almost replaced with the much efficient LED lamps, it's now time for the ceiling fans to become smarter and more efficient.
