bldc ceiling fan controller circuit with remote price in bangladesh

A BLDC (Brushless DC) ceiling fan controller with a remote receives signals from a remote control to manage the fan's speed and functions. It converts the incoming AC power to DC and then uses a microcontroller to generate a Pulse Width Modulation (PWM) signal, which drives a three-phase inverter to power the brushless DC motor. This system provides efficient, stepless speed control and features multiple protection circuits for overcurrent, overheating, and other potential issues.

Key Components and Functionality

1. AC to DC Power Supply (SMPS):

The initial step involves converting the main AC power supply to a stable DC voltage for the controller and motor.

2. Microcontroller (MCU):

This is the "brain" of the system, receiving commands from the remote control.

3. Remote Control (Transmitter):

The user interacts with the fan through the remote, which sends signals (e.g., IR or RF) to the controller.

4. PWM Generator:

The microcontroller generates a PWM signal to control the motor's speed, allowing for smooth and precise adjustments.

5. Inverter/Motor Driver:

This component takes the PWM signal and converts it into the three-phase AC power required to drive the BLDC motor at the commanded speed.

6. BLDC Motor:

The brushless DC motor itself, which runs on the controlled power from the inverter.

7. Protection Circuits:

These integrated circuits monitor the system for faults like overcurrent, overvoltage, and dry-burning conditions, ensuring the safety and longevity of the fan and controller.

How it Works

1. Signal Reception:

When a button is pressed on the remote, a signal is sent to the receiver in the ceiling fan.

2. Signal Interpretation:

The microcontroller receives this signal and interprets it to determine the desired fan speed or function.

3. Speed Control:

The microcontroller then adjusts the duty cycle of the PWM signal sent to the inverter.

4. Motor Drive:

The inverter uses this PWM signal to vary the voltage and frequency supplied to the BLDC motor, thus controlling its rotational speed.

5. Efficient Operation:

The result is a highly energy-efficient fan that can be precisely controlled remotely across a range of speeds.
