Bldc ceiling fan controller circuit diagram.

Dc ceiling fans are very common and used everywhere. In the above ceiling fan speed control wiring diagram i shown the main winding running winding and i connect run wire of motor to the speed control switch and you can see it in above diagram that connection of run wire of motor in switch l point and and 1 and 2 for capacitor. The circuit is built around an ne555 ic1 a drv10866 ic2 and a few other components. 1 shows the circuit of a sensor less bldc motor driver.

A bldc fan s speed can be varied smoothly without the usual steps associated with a normal ac fan. It features the drv10983 24v three phase motor driver to drive motors with sinusoidal current and sensorless control. This video demonstrates a highly efficient bldc ceiling fan using complete microchip solutions such as microcontrollers power management solutions control. From 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.

This reference design is a complete solution for a brushless dc ceiling fan controller that runs from ac power. Here in this video i will express the principle and circuit of a dc ceiling fan.
