1200W PWM Motor Speed Controller with Potentiometer
1200W PWM Motor Speed Controller with Potentiometer
The 1200W PWM Motor Speed Controller with Potentiometer is a high-power, pulse-width modulation (PWM) based motor speed controller designed to regulate the speed of DC motors. This component is ideal for applications requiring precise speed control, high power handling, and ease of operation.
The 1200W PWM Motor Speed Controller with Potentiometer is designed to control the speed of DC motors by generating a PWM signal that switches the motor on and off at high frequencies. The potentiometer allows for manual adjustment of the motor speed, providing a convenient way to set the desired speed.
The controller works by converting the input voltage to a PWM signal, which is then sent to the motor. The PWM signal is generated based on the position of the potentiometer, allowing the user to adjust the motor speed in real-time.

Component Documentation: 1200W PWM Motor Speed Controller with PotentiometerOverviewThe 1200W PWM Motor Speed Controller with Potentiometer is a high-power motor controller designed to regulate the speed of DC motors up to 1200W. It features a built-in potentiometer for manual speed adjustment and PWM (Pulse Width Modulation) output for precise motor control. This component is suitable for a wide range of applications, including robotics, industrial automation, and DIY projects.Technical SpecificationsInput Voltage: 12V - 24V DC
Output Power: 1200W
PWM Frequency: 15 kHz
Potentiometer Range: 0 - 100% ( variable speed control )
Operating Temperature: -20C to 85C
Dimensions: 70mm x 50mm x 30mmConnection DiagramThe motor speed controller has the following connections:VCC (Input Voltage): Connect to a 12V - 24V DC power source
GND (Ground): Connect to the negative terminal of the power source and the motor
OUT+ (Output Positive): Connect to the positive terminal of the motor
OUT- (Output Negative): Connect to the negative terminal of the motor
POT (Potentiometer): Connect to a potentiometer or a variable resistor for manual speed control
PWM (Pulse Width Modulation): Connect to a microcontroller or a logic level signal for PWM controlCode Examples### Example 1: Arduino Uno Control with PotentiometerIn this example, we will use an Arduino Uno to control the motor speed using the built-in potentiometer.```cpp
const int potPin = A0; // Potentiometer connected to analog input A0
const int pwmPin = 9; // PWM output connected to digital pin 9void setup() {
pinMode(pwmPin, OUTPUT);
}void loop() {
int potValue = analogRead(potPin);
int pwmValue = map(potValue, 0, 1023, 0, 255);
analogWrite(pwmPin, pwmValue);
delay(10);
}
```In this code, we read the analog value from the potentiometer and map it to a PWM value between 0 and 255. We then write the PWM value to the digital pin connected to the motor speed controller's PWM input.### Example 2: Raspberry Pi Control with PythonIn this example, we will use a Raspberry Pi to control the motor speed using Python and the RPi.GPIO library.```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
pwm_pin = 18 # PWM output connected to GPIO 18
GPIO.setup(pwm_pin, GPIO.OUT)pwm_frequency = 50
pwm = GPIO.PWM(pwm_pin, pwm_frequency)while True:
for dc in range(0, 101, 1):
pwm.ChangeDutyCycle(dc)
time.sleep(0.01)
for dc in range(100, -1, -1):
pwm.ChangeDutyCycle(dc)
time.sleep(0.01)
```In this code, we set up the PWM output on GPIO 18 and create a PWM object with a frequency of 50 Hz. We then create a loop that varies the duty cycle of the PWM signal from 0 to 100% and back to 0, effectively creating a speed ramp.Note: Make sure to adjust the pin connections and frequencies according to your specific setup and requirements.
