Bldc Ceiling Fan Controller Circuit Diagram

Circuit of brushless dc motor driver.

Bldc ceiling fan controller circuit diagram.

Here in this video i will express the principle and circuit of a dc ceiling fan. Brushless dc motor driver circuit. 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 video demonstrates a highly efficient bldc ceiling fan using complete microchip solutions such as microcontrollers power management solutions control.

This reference design is a complete solution for a brushless dc ceiling fan controller that runs from ac power. 1 shows the circuit of a sensor less bldc motor driver. 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 ucc28630 converts 90 265 vac into 24 vdc.

The circuit is built around an ne555 ic1 a drv10866 ic2 and a few other components. It features the drv10983 24v three phase motor driver to drive motors with sinusoidal current and sensorless control.
