Product Description:

Power your demanding robotic and automation projects with our 30 RPM 12V DC Johnson Geared Motor (Grade B). This workhorse motor is renowned for delivering high torque at a very low speed, making it an excellent choice for applications requiring controlled, powerful movement in a compact form factor. While designated "Grade B," it still offers excellent performance and durability for a wide range of hobbyist, educational, and light industrial uses, providing a cost-effective alternative without compromising on essential functionality.

At its core, this Johnson geared motor combines a high-speed DC motor with a robust metal gearbox. This gearbox precisely reduces the motor's high base RPM to a steady 30 Revolutions Per Minute (RPM) at its nominal 12V DC operating voltage, while simultaneously amplifying the output torque significantly. This makes it ideal for tasks that require substantial force to drive loads or overcome friction in mechanical systems.

Common applications for the 30 RPM 12V DC Johnson Geared Motor (Grade B) include:

• Mobile Robotic Platforms: Excellent for driving wheels on line-follower robots, obstacle-avoiding robots, AGVs, and other mobile chassis where controlled speed and high pushing/pulling force are needed.

• Robotic Arms & Actuators: Provides the necessary torque for precise control of robotic arm joints, grippers, or automated dispensing mechanisms.

• Pan/Tilt Systems: Enables smooth and deliberate movement for surveillance cameras, sensors, or other devices requiring controlled angular positioning.

• Automated Machinery: Suitable for use in vending machines, automatic actuators, cleaning machines, or small conveyor systems.

• DIY Projects: Perfect for custom-built mechanisms like automated gates, smart feeders, or any project where reliable, high-torque, low-speed motion is paramount.

The Johnson geared motor typically features a durable construction with a metal gearbox for long service life and often comes with an off-centered side shaft and multiple M3 mounting holes for easy integration into your designs. While "Grade B" motors might have minor cosmetic differences or slightly less extreme torque figures compared to "Grade A" versions, they maintain critical performance specifications, making them a reliable and economical choice.

Upgrade your projects with dependable, high-torque motion.

The Johnson High Torque 12V 30RPM DC Geared Motor is a robust, heavy-duty motor designed for applications requiring low speed and high torque. It features a durable metal gearbox and is widely used in robotics, home automation, conveyor belts, smart farming tools, and DIY engineering systems.

This Grade A motor delivers consistent torque, reduced gear backlash, and improved endurance compared to standard variants. Its compact cylindrical design and D-type shaft allow easy integration into mechanical assemblies and frames.

Popular among makers, engineers, and students, it is compatible with Arduino, Raspberry Pi, and motor drivers like L298N and BTS7960.

Key Features:

• High Torque Output: Delivers approximately 15–25 kg·cm torque, ideal for heavy-load applications in robotics and automation.

• Durable Metal Gearbox: Built with premium Grade A metal gears for long-lasting, low-maintenance performance.

• Reversible Rotation: Change direction easily by switching power polarity—perfect for two-way motor control systems.

• DIY & Industrial Ready: Ideal for Arduino, Raspberry Pi, and compatible with motor drivers like L298N, BTS7960, and relay modules.

• Wide Applications: Use in smart farming, conveyor belts, robotic arms, 3D printer modifications, and more.

How to Use:

Wiring & Power Supply:

• Connect the motor terminals to a 12V DC power source.

• To reverse direction, switch polarity of the connections.

• For controlled operation, use an H-Bridge Motor Driver (e.g., L298N or BTS7960) with PWM and direction pins from Arduino or microcontroller.

Typical Applications:

• Robotic arms and mobile robots

• Conveyor belts and pick-and-place systems

• Smart irrigation and greenhouse systems

• Automated gates and lifts

• Mini winches and rotating mechanisms

Arduino Integration (Using L298N):

int motorPin1 = 8;
int motorPin2 = 9;

void setup() {
  pinMode(motorPin1, OUTPUT);
  pinMode(motorPin2, OUTPUT);
}

void loop() {
  // Clockwise
  digitalWrite(motorPin1, HIGH);
  digitalWrite(motorPin2, LOW);
  delay(5000);

  // Counter-Clockwise
  digitalWrite(motorPin1, LOW);
  digitalWrite(motorPin2, HIGH);
  delay(5000);
}
