JLCPCB Solution: Air Multiplier
An air multiplier, sometimes called a bladeless fan, is a fan that blows air from a ring with no external blades. Its vanes are hidden in its base and direct the collected airflow through a hollow tube or toroid, blowing a thin high-velocity smooth airflow from holes or a continuous slot across the surface of the tube or toroid. The first concept was created by Toshiba in 1981.-Wikipedia
Step 1: AC to DC Circuit
![JLCPCBAC to DC.png](//image.easyeda.com/pullimage/hYfCQJenurYgunh4aICOy42Sxqd2vGGigRTJa6Qx.png)
Input AC 220V; need to output 15V DC power supply, this is the very classic MP150 non-isolated power supply circuit. By adjusting the current of the control terminal to change the amplitude, to achieve precise adjustment purposes.
PCB Manufactured by [JLCPCB](JLCPCB) the largest PCB prototype in China, they can provide PCB samples for 5 pcs by $2 within 2 days.
Step 2: Power Detection and Buck Circuit
![Power detection and buck circuit.png](//image.easyeda.com/pullimage/SA9Zx2crJ8NidMXYEvQCE7XIsBZHob2dzeAOwUSz.png)
The input voltage can be directly detected by MCU after voltage division and can be used for circuit protection.
15V dc voltage through 78L05 buck voltage to 5V, for MCU use
Step 3: MCU

Here we use SN32F7051BF. You can get it on [LCSC](LCSC)
MCU is responsible for gear setting and switching, indicating the running status, the most important role in motor control.
Step 4: Brushless DC Motor

The above is a three-phase full-bridge drive circuit for a brushless motor. It uses six N-channel MOSFETs (FMD3N50E5) as power output components, and the output current can reach tens of amperes during operation.
Use IR2101 as the drive of MOS tube, IR2101 is a dual-channel, gate drive, high-voltage high-speed power driver. SCM drives IR2101 by outputting controllable PWM signal
Step 5: Brushless Motor Zero Crossing Problem
![jlcpcbBrushless DC motor.png](//image.easyeda.com/pullimage/OFWmhkJniRZ6P26mnzWtCfbLkMM6RsMnS0jcqGji.png)
The brushless motor senses the position of the permanent magnet's magnetic pole through the hall element and transmits it to MCU. The MCU timely switches the current direction in the coil to ensure the magnetic force in the right direction to drive the motor
Step 6: Brushless Motor Zero Crossing Problem
![jlcpcb zero.png](//image.easyeda.com/pullimage/9rOkZlDYxpuSSnL1jcqrOcuKpuuusddZghI9Dtrq.png)
The brushless motor senses the position of the permanent magnet's magnetic pole through the hall element and transmits it to MCU. The MCU timely switches the current direction in the coil to ensure the magnetic force in the right direction to drive the motor
Step 7: Indicating Operating Status
