The 3.5RPM 12V Low Noise DC Gear Motor (Grade A) is a compact and powerful gear motor engineered for low-speed, high-torque applications. Designed with hardened metal gears, it provides long operational life, superior wear resistance, and quiet performance.

This motor is ideal for:

Robotic arms
Smart door locks
Conveyor systems
Automated curtain openers
DIY model projects
Mini CNC or gear-driven mechanisms

Thanks to its reduction gear assembly, it outputs very low rotational speed (3.5 RPM) with sufficient torque for lifting or rotating mechanical components with precision. The low noise level and metal gear construction make it suitable for applications that demand quiet operation and durability.

Technical Specifications:

Parameter	Specification
Operating Voltage	12V DC
No-Load Speed	3.5 RPM ±10%
Torque Output	~20–30 kg·cm (varies by load)
Gear Type	Full metal gears
Noise Level	Low noise motor design
Motor Type	Brushed DC motor with gear reduction
Shaft Diameter	6 mm (D-type or round, varies by model)
Shaft Length	Approx. 15–20 mm
Motor Body Length	Approx. 60–70 mm
Weight	~150–180 grams
Direction Control	Reversible with polarity change
Mounting Holes	Yes (standard tapped mounting holes)

How to Use:

Wiring & Power:

Connect the +12V and GND wires to a regulated DC power supply or motor driver.
For direction control, reverse the polarity of the wires.
For Arduino/MCU use, connect via an L298N, L9110, or relay module for safe switching.

Typical Circuit Setup with L298N Motor Driver:

Motor Wire	Connect To (L298N)
Red	OUT1
Black	OUT2
+12V Supply	VCC
GND	GND
ENA	PWM Pin (Arduino)
IN1, IN2	Digital Pins (Arduino)

Arduino Code:

int in1 = 7;
int in2 = 6;

void setup() {
pinMode(in1, OUTPUT);
pinMode(in2, OUTPUT);
}

void loop() {
digitalWrite(in1, HIGH);
digitalWrite(in2, LOW); // Motor rotates in one direction
delay(5000);

digitalWrite(in1, LOW);
digitalWrite(in2, HIGH); // Reverse direction
delay(5000);
}

Applications

Hobbyist Robotics: For controlling precise movements in robots or other mechanical projects.
Low-Speed Precision Mechanisms: For applications where slow, steady movement is essential, such as camera sliders, conveyor belts, or timers.
Quiet Machines: Devices where minimizing noise is important, such as in quiet fans, pumps, or actuators.

This motor could be used in a wide range of applications where precision and low noise are required, and the metal gears will ensure it can handle the mechanical demands without failure.
