Details
This Small DC Motor 3V-6V is a general-purpose permanent-magnet brushed DC motor widely used in school science projects, robotics kits, toys and compact DIY mechanisms. Designed for low-voltage operation, it can run directly from two to four AA cells, a 3.7V Li-ion battery, or a regulated 5V/6V DC supply. The motor converts electrical energy into rotational motion using a brushed commutator and internal permanent magnets, making it simple, inexpensive and easy to control.
For basic use, connect the two motor terminals to a DC supply; reversing the positive and negative connections reverses the shaft direction. For Arduino, Raspberry Pi, ESP32 or other microcontroller projects, use a suitable motor driver such as L293D, L298N, TB6612FNG, a MOSFET driver, or relay module because a DC motor draws more current than a GPIO pin can safely provide. Speed can be varied using PWM from a motor driver, and torque/load performance will depend on supply voltage, battery strength and the mechanical load.
The motor is commonly used with small plastic propellers, toy wheels, pulleys, gears and model-making parts. It is suitable for mini robots, fan prototypes, moving displays, vibration mechanisms, science fair models, electric cars, boats and educational experiments demonstrating polarity, speed control and mechanical motion. As with most generic hobby motors, speed and current can vary slightly between batches and with load.
In the box: 1 x Small DC Motor 3V-6V. Pin notes: the motor has two solder terminals only; there is no polarity marking for permanent direction because polarity reversal simply reverses rotation. Use flyback protection when switching with transistors or relays.
