N20 Gear motors

What Is N20 Gear Motor?

The N20 gear motor is a compact DC motor with an integrated gearbox that allows it to reduce output shaft speed while delivering higher torque.

The Name Origin of The N20 Gear Motor

In the technological world of DC motors, sometimes a simple name hides a curious story. Let Annie take you to uncover the mystery of the “N20 gear motor “!

The N20 gear motor is a compact direct current (DC) motor, and the term “N20” indicates its physical size. It usually consists of an N20 motor combined with a spur gear reducer. The gear reducer converts the high speed, low torque output of the N20 motor into low-speed, high-torque output, thus providing greater torque for a wide range of applications. You can find the N20 micro gear motor in our range of spur gear motors.

What Are The Advantages of Brushed Spur Gear Motors?

Spur Gearhead: These motors come with a spur gearhead, which provides power and practicality for low-torque operations. The gearhead helps to reduce the output shaft speed while increasing the torque, making them suitable for applications that require precise and controlled motion.

Simple Design and Quiet Operation: The motors have a straightforward design and operate quietly, making them favorable for applications where noise reduction is essential.

Space-saving and Lightweight: With a width of only 12 mm and a weight of 10 g, these motors are compact and lightweight, making them easy to integrate into space-constrained devices or projects.

Bronze Output Bearings: The gearhead is equipped with bronze output bearings, which are known for their resistance to friction and wear-and-tear. This makes the motors suitable for heavy-duty industrial environments where durability is crucial.

Smooth Motion at Any Speed: Thanks to their simplified brushed motor design, these motors deliver smooth motion at any operating speed, ensuring precision and stability in various applications.

Wide Operating Temperature Range: The motors feature high-quality bronze bearings and metal cores, allowing them to operate safely in temperatures ranging from -10°C to 60°C. This broad temperature range makes them suitable for use in different environmental conditions.

Decreased Risk of Machine Failure: Spur gears are less likely to slip during operation, reducing the risk of machine failure and ensuring more reliable performance.

Due to their excellent features and capabilities, these 3V brushed DC geared motors are commonly used in industrial automation, modeling projects, robotics, and other applications that require low-torque and efficient motion control. Their reliable and robust performance in challenging environments makes them a popular choice for many engineering and hobbyist projects.

N20 Planetary gear motor offers a significant gear reduction, allowing for precise control and increased torque output. This makes it suitable for applications requiring precise motion and handling heavy loads. Compact and Lightweight: With its compact design and lightweight properties, the N20 Planetary gear motor can easily fit into small spaces and devices. Its reduced size makes it versatile for various space-constrained applications.

N20 Worm Gear Motor: The N20 worm gear motor features a worm gear mechanism in its gearbox. Worm gears consist of a spiral-shaped “worm” gear that meshes with a cylindrical gear, also known as the worm wheel. This arrangement allows for a high gear ratio, which means it can provide a significant reduction in output shaft speed while increasing torque. N20 worm gear motors are commonly used in applications that require high gear reduction and better holding capabilities since the worm gear design prevents backdriving.

The Application of The N20 Mini Gear Motor

The N20 gear motor is widely used in various products due to its compact size, high efficiency, and high torque output. Here are some common applications of the N20 gear motor:

Robotics: N20 motors are used for joint actuation and motion control in small robotic arms, leg movements, and rotating components like robot eyes and heads.

Camera Gimbal: In photography and filming equipment, N20 motors are used to control the rotation and tilt of camera gimbals, ensuring smooth and stable camera movements.

Smart Home Devices: N20 motors are employed in smart home products to control the motion and positioning of devices such as smart curtains, door locks, and automatic doors. Model Making: N20 motors are popular choices in model airplanes, cars, boats, and other model-making projects, providing power and motion control.

Medical Equipment: Some medical devices use N20 motors for controlling the movement and positioning of small medical instruments. Automation Equipment: N20 motors are utilized in various small automation devices, including vending machines, automatic door locks, and automatic adjustment mechanisms.

What Is The Use of N20 Gear Motor?

The N20 motor is proving to be well suited for compact IIOT(Industrial Internet of Things) applications such as electric locks, webcam panning mechanisms and other similar actuator products that require excellent torque within a limited size and reduced weight.

What size is the N20 gearmotor?

N20 DC motor size 15 x 12 x 10 mm. Depending on the speed ratio, the gearbox length is available in two options: 9mm and 11mm. The N20 gearmotor comes in various sizes, with different shaft lengths and shapes that can be customized according to specific requirements.

What Is The Difference Between N20 and N10 Gear Motors?

The N10 motor is smaller and lighter than the N20 motor. Both types of DC gear motors are available to us. In addition, it is important to mention that torque and stall current exhibit a near linear relationship in these motors, which means that as you increase the torque requirement, the current will also increase proportionally.
