300RPM 12V DC Center Shaft Metal Geared Motor

300RPM 12V DC Center Shaft Metal Geared Motor provides an excellent balance of speed and torque for medium-sized robotics and automation projects. This geared motor integrates a robust metal gearbox directly onto the DC motor, translating the motor’s high speed into significant turning force (torque) at a manageable output speed of 300 Revolutions Per Minute (RPM). Operating efficiently at 12 volts, this unit is highly favored by engineers and hobbyists for its reliability and its center shaft design, which simplifies mounting and power transmission in wheeled and tracked platforms. You can easily drive light to moderate loads with precision, making this motor a workhorse for applications requiring controlled, powerful movement.

Key Features:

• Optimized Speed and Torque: Delivers a practical 300 RPM output speed coupled with enhanced torque for driving mobile chassis and mechanisms.
• Center Shaft Design: The output shaft sits centrally on the face of the motor, making mounting and alignment straightforward for robotic wheels.
• Durable Metal Gearbox: Features all-metal gears, ensuring longevity, higher load capacity, and greater resistance to wear compared to plastic gear models.
• 12V Operating Voltage: Runs optimally on a standard 12V DC supply, which is common in battery-powered systems and desktop setups.
• Low Noise Operation: Despite the metal gears, the motor operates relatively quietly, suitable for indoor and experimental environments.

Technical Specifications:

• Rated Voltage: 12 V DC
• No-Load Speed: ≈ 300 RPM (Revolutions Per Minute)
• No-Load Current: ≈ 150 mA to 300 mA
• Stall Torque: Varies by specific gear ratio (Typically 3 kg·cm to 5 kg·cm)
• Gearbox Reduction Ratio: Varies (Determines final torque and speed)

Mechanical Specifications:

• Gearbox Material: Metal
• Shaft Type: Center Shaft, Cylindrical or D-cut
• Shaft Diameter: Typically 6 mm
• Mounting: Two or four mounting holes on the faceplate for secure attachment to a chassis.

Dimensions:

• Motor Body Diameter: ≈ 37 mm
• Motor Body Length: ≈ 50 mm (excluding shaft)
• Shaft Length: ≈ 15 mm to 20 mm
• Weight: ≈ 200 g to 250 g

Pinout and Wiring:

• Pin 1 (Positive Terminal): Connect to the 12V power supply’s positive (+) terminal to drive the motor in one direction.
• Pin 2 (Negative Terminal): Connect to the 12V power supply’s negative (-) or ground terminal.
• Direction Reversal: Simply reverse the polarity (swap the connections to Pin 1 and Pin 2) to change the motor’s direction of rotation. Use an H-bridge motor driver (like an L298N or similar) for electronic speed and direction control.

Commonly Used in:

• Autonomous Mobile Robots (AMRs): Providing propulsion for small to medium-scale indoor robots.
• Automated Gimbals and Camera Sliders: Used for precise, controlled movement in photography equipment.
• Educational Robotics Platforms: Forming the basis of drive systems for school and competition robots.

Applications:

• Wheeled Robot Drive Systems: Driving wheels directly or through a simple gear train for mobility.
• Conveyor Belts: Providing the motive force for small-scale material handling systems.
• Linear Actuators and Lifts: Using its torque to move loads vertically or horizontally via screw drives.

Equivalent Models:

• BO Motors: Lower-cost, lower-torque alternatives often used in lightweight beginner kits.
• High-Torque Motors (e.g., 100 RPM @ 12V): Models offering lower speed but significantly higher torque for heavy-duty applications.
• Brushed DC Motor with Planetary Gearbox: A premium, often more compact and robust alternative.

Package Includes:

• 1 x 300RPM 12V DC Center Shaft Metal Geared Motor
