12mm 2.4V 5V 12V N20 Gear Reduction Motor with Encoder NFP-GM1024-N20VA-EN

High Torque N20 Gear Motor Parameters

Do N20 Motors All Use the Same Input Gear Size?

First, N20 gearbox motors do not always use the same input gear size. The term “N20” mainly refers to the motor size and body shape. However, the input gear, gearbox design, and gear ratio can vary between models.

Also, different gear ratios provide different output speeds and torque levels. Therefore, check the motor voltage, gear ratio, speed, and torque before selecting a model.

Key Features

• Compact N20 motor with metal reduction gearbox
• 2.4V, 5V, and 12V DC motor options
• Gear ratios from 50:1 to 1,000:1
• Low-speed and high-torque output options
• Encoder feedback for speed and position control
• Suitable for robots, smart locks, and small drive systems

Single Motor Technical Data

Next, compare the three motor options below. For example, the 12V version has a higher no-load speed, while the lower-voltage versions work with smaller power supplies.

First, review the 2.4V motor data below. As the ratio increases, the output speed drops. At the same time, the available torque increases.

Note: all reduced no-load speeds have a tolerance of ±15%.

Next, the 5V version provides the same gearbox ratio range. Therefore, you can choose the ratio based on the speed and torque needed by your system.

Note: all reduced no-load speeds have a tolerance of ±15%.

In addition, the 12V motor provides higher output speeds at the same ratios. However, a higher gear ratio still lowers the output speed and raises the available torque.

Note: all reduced no-load speeds have a tolerance of ±15%.

Reduction DC Gear Motor with Encoder Reference Size

Can an N20 Gear Motor Drive a 1 lb Robot?

First, the answer depends on the selected gear ratio, wheel size, required speed, and robot load. N20 motors come with many gear ratios and torque levels. Therefore, select the motor from the actual drive requirements rather than the N20 frame size alone.

For example, a higher reduction ratio can provide more output torque for the drive wheels. However, it also lowers the output speed. As a result, the correct ratio depends on the balance between torque and travel speed.

Also, check the motor voltage before selecting the battery and motor driver. These N20 motor options use 2.4V, 5V, or 12V DC base motors. Therefore, the power supply and driver should match the selected motor.

Selection Points

• Confirm the total robot weight.
• Check the required wheel speed.
• Choose the correct wheel diameter.
• Calculate the required drive torque.
• Select a suitable gearbox ratio.
• Match the battery voltage to the motor.
• Allow enough current for starting and load changes.

N20 Gear Motor Encoder Wiring

Next, connect the motor and encoder wires according to the functions below. In addition, confirm the encoder supply voltage before connecting it to your controller.

• Red Wire: DC motor negative pole (−), rated motor voltage
• Black Wire: Encoder positive pole (+), 3.0V
• Yellow Wire: Encoder output signal B
• Green Wire: Encoder output signal A
• Blue Wire: Encoder negative pole (−), GND
• White Wire: DC motor positive pole (+), rated motor voltage

Typical Applications

Finally, the compact size and encoder feedback make this N20 gear motor useful for many small drive systems. For example, common applications include:

• Electronic door locks
• Smart switches
• Hair straighteners
• Small lifting systems
• Smart wearable devices
• 3D printing equipment
• Hair curlers
• Safes
• Electric screwdrivers
• Display stands
