12V 1000rpm Micro Gear Motor N20

 The N20 DC motor is commonly used in small-scale robotics projects, toys, and other automation applications.  

• "N20" refers to the size of the motor. It indicates a standard for this type of motor, specifically its dimensions. Other N-series motors may come in different sizes.
• RPM value indicates the speed. It shows how many revolutions per minute the motor can achieve when running without load. The speed may decrease under load.
• Voltage value is the nominal operating voltage of the motor. This means the voltage specified in the product name corresponds to its rpm and torque values. It can operate at other voltages as well, but performance may vary.
• "DC" motor means it runs on direct current (DC). When power is supplied, the motor spins in one direction. To change the direction, you must reverse the polarity of the connections or add a direction control circuit to the motor.
