The DC 9-60V Motor Controller is a versatile device designed to regulate the speed and direction of DC motors operating within a voltage range of 9 to 60 volts. It provides precise control over motor performance, making it ideal for applications requiring variable speed, smooth acceleration, and bidirectional operation. This component is widely used in robotics, electric vehicles, conveyor systems, and other motor-driven systems.
The DC 9-60V Motor Controller is designed to handle a wide range of motor control requirements. Below are its key technical details:
Parameter | Specification |
---|---|
Input Voltage Range | 9V to 60V DC |
Output Current | Up to 30A (varies by model) |
Control Mode | Pulse Width Modulation (PWM) |
PWM Frequency | 15 kHz to 25 kHz |
Speed Adjustment Range | 0% to 100% |
Direction Control | Forward and Reverse |
Efficiency | ≥ 90% |
Operating Temperature | -20°C to 50°C |
Dimensions | Varies by model (e.g., 100x60x30 mm) |
The motor controller typically includes the following terminals for connections:
Pin/Terminal Name | Description |
---|---|
VIN+ | Positive input voltage terminal (connect to power supply +) |
VIN- | Negative input voltage terminal (connect to power supply -) |
M+ | Positive motor terminal (connect to motor +) |
M- | Negative motor terminal (connect to motor -) |
PWM Input | Optional input for external PWM signal (for speed control) |
Direction Control | Optional input for controlling motor direction (e.g., forward/reverse) |
Potentiometer | Built-in or external potentiometer for manual speed adjustment |
The DC 9-60V Motor Controller can be controlled using an Arduino UNO to provide a PWM signal for speed control and a digital signal for direction control. Below is an example code snippet:
// Define pins for PWM and direction control
const int pwmPin = 9; // PWM output pin for speed control
const int dirPin = 8; // Digital output pin for direction control
void setup() {
pinMode(pwmPin, OUTPUT); // Set PWM pin as output
pinMode(dirPin, OUTPUT); // Set direction pin as output
}
void loop() {
// Set motor direction to forward
digitalWrite(dirPin, HIGH); // HIGH for forward, LOW for reverse
// Gradually increase motor speed
for (int speed = 0; speed <= 255; speed += 5) {
analogWrite(pwmPin, speed); // Write PWM value (0-255)
delay(100); // Wait 100ms
}
// Gradually decrease motor speed
for (int speed = 255; speed >= 0; speed -= 5) {
analogWrite(pwmPin, speed); // Write PWM value (0-255)
delay(100); // Wait 100ms
}
// Reverse motor direction
digitalWrite(dirPin, LOW); // Set direction to reverse
delay(2000); // Run in reverse for 2 seconds
}

Q1: Can I use this controller with a 12V motor?
A1: Yes, the controller supports a wide voltage range (9-60V), so it is compatible with 12V motors.
Q2: What happens if I exceed the current rating?
A2: Exceeding the current rating may damage the controller. Use a motor with a current draw within the specified limit.
Q3: Can I control multiple motors with one controller?
A3: No, this controller is designed for a single motor. Use separate controllers for multiple motors.
Q4: Is it safe to use this controller outdoors?
A4: Unless specified as weatherproof, the controller should be used in a dry, protected environment.
Q5: Can I use a battery as the power source?
A5: Yes, as long as the battery voltage is within the 9-60V range and can supply sufficient current.
