How to Use Greartisan DC 12V 45RPM Turbo Worm Geared Motor : Examples, Pinouts, and Specs

The Greartisan DC 12V 45RPM Turbo Worm Geared Motor (part number JSX180-370) is a high-quality geared motor that provides a slow rotation speed of 45 rotations per minute (RPM) at a stable 12V DC supply. The worm gear mechanism ensures high torque and reduces gear backlash, making it suitable for applications requiring precise motion control and load-driving capabilities.

• Robotics
• Automatic window/door openers
• Miniature winches
• Hobby projects
• Custom actuators

The Greartisan JSX180-370 motor has two terminals for power connection:

1. Power Supply: Connect a 12V DC power supply to the motor terminals, ensuring correct polarity.
2. Control: To control the motor's direction, reverse the polarity of the power supply. This can be done using a DPDT (Double Pole Double Throw) switch or an H-bridge circuit.
3. Speed Control: To control the speed, use a PWM (Pulse Width Modulation) signal. This can be achieved using a microcontroller like an Arduino UNO.

• Do not exceed the recommended voltage as it may damage the motor.
• Ensure proper heat dissipation to prevent overheating during prolonged use.
• Use a suitable motor driver when interfacing with microcontrollers to protect the control circuitry.
• Incorporate an appropriate fuse or current protection device to prevent damage from overcurrent conditions.

// Example code to control Greartisan DC 12V 45RPM Motor with Arduino UNO
#include <Arduino.h>

const int motorPin = 3; // Connect to the motor control circuit

void setup() {
  pinMode(motorPin, OUTPUT);
}

void loop() {
  analogWrite(motorPin, 128); // Set speed at 50% duty cycle (adjust value between 0-255)
  delay(1000);                // Run for 1 second
  analogWrite(motorPin, 0);   // Stop the motor
  delay(1000);                // Wait for 1 second
}

Note: The above code assumes the use of a PWM-capable pin and a motor driver or transistor to control the motor speed.

• Motor not running: Check power supply and connections. Ensure the voltage is 12V DC and polarity is correct.
• Low torque or speed: Verify that the motor is not overloaded and the power supply can deliver sufficient current.
• Overheating: Ensure adequate ventilation and check for any mechanical binding in the application.

• If the motor does not operate, double-check wiring and connections.
• Use a multimeter to verify the power supply voltage and motor resistance.
• For direction control issues, ensure that the H-bridge or DPDT switch is functioning correctly.

Q: Can I run this motor at a voltage lower than 12V? A: Yes, but the speed and torque will be reduced accordingly.

Q: Is it possible to control this motor with a simple on/off switch? A: Yes, but you will not have speed or direction control.

Q: How can I reverse the direction of the motor? A: Reverse the polarity of the power supply to the motor, or use an H-bridge circuit for electronic control.

Q: What is the maximum load this motor can handle? A: The motor has a rated torque of 10kg.cm and a stall torque of 30kg.cm. Do not exceed these values to prevent damage.
