4000W AC 0-220V 20A PWM Pulse Width Modulator Motor Speed Regulator

Description

What it is

The 4000W AC 0-220V 20A PWM Speed Controller for Electric Motor is an electronic device that allows the control of the speed of an AC electric motor by varying the amplitude of the PWM (Pulse Width Modulation) signal sent to the motor.

Features

• Maximum Power: 4000W (linear load)
• Input Voltage: AC 100V-220V
• Maximum Current: 20A
• Dimensions: 91 * 59 (excluding handle) * 34MM

What it is for

This PWM controller is ideal for regulating the speed of electric motors, controlling a burner, or any other device that requires a wide range of power. It is particularly useful for makers working on electronic energy projects. Examples of use: building a temperature control system with an electric burner, adjusting the intensity of the flame through the PWM controller.

This PWM modulator is ideal for regulating the speed of electric motors, burner control, or any other device that requires a wide range of power. It is particularly useful for makers working on electronic energy projects.

What you need

• Arduino Uno
• USB Cable
• Compatible Electric Motors
• Position Sensors (optional)
• Fuse

Steps

1. Connect the PWM modulator to AC power 100V-220V.
2. Connect the module power supply to a fuse to protect the system from overloads.
3. Use the input and output connectors to connect the motor or device to the PWM modulator.
4. Connect the PWM modulator data line to the Arduino for control.
5. Write an Arduino sketch that sends PWM signals to the module.
6. Adjust the speed and power parameters through the Arduino software.
7. Check the output with a multimeter or oscilloscope.
8. Optimize the regulation based on project requirements.

Example code

//Esempio di codice Arduino
void setup() {
  pinMode(9, OUTPUT);
}

void loop() {
  analogWrite(9, 128); //Regolare il valore tra 0 e 255 per variare la velocità del motore.
}

Mini project

Build a temperature control system with an electric burner. Use the PWM modulator to regulate the intensity of the flame.

Common mistakes

• Do not verify the compatibility of the motor or device before installation.
• Omit the fuse protection.
• Set a PWM value that exceeds the module’s capabilities.
• Do not test the system with low load before using it at full capacity.

Recommended accessories

• Arduino Uno
• Electric motors compatible 20A
• Temperature sensors
• 16A fuse

Frequently asked questions
