## Description

Ideal for projects powered directly from solar panels, this 3-6V micro motor offers very low consumption and easy starting in small applications. It works with reverse polarity for quick change of direction of rotation, reaches up to 4500 rpm without load and has a compact housing, suitable for solar toys, mini mechanisms and educational experiments.
Motor type 300, ideal for applications where the power comes directly from solar panels, considering the very low consumption.
Due to its ability to operate with reverse polarity, the motor offers increased flexibility in design and use, being suitable both for applications that require clockwise and counterclockwise rotation.
With a compact construction and performance optimized for solar use, this motor is ideal for integration into small devices, solar toys, and educational experiments that highlight the principles of renewable energy.
Specifications:
Supply voltage: 3-6VDC
Speed without load: 3500-4500 rpm/min
Current without load: about 25mA
Color: Silver
Reverse polarity compatibility: The motor can operate with reverse polarity, allowing reverse rotation
Wire length: 30cm (may vary depending on the batch)
Dimensions mm: 24.5 x 12.5mm (Diameter x Height)
Use:
The motor can be connected to a solar panel (up to 6VDC) or to a battery with the specified voltage of DC3V-6V. The polarity can be reversed to change the direction of rotation of the motor.
Due to the reverse polarity compatibility, you can easily change the direction of rotation by connecting the positive terminal to the negative wire and the negative terminal to the red wire, or vice versa, depending on the colors of the wires.
After making the connections, the motor should start running immediately. The rotation speed can vary depending on the applied voltage and the intensity of the sunlight, in the case of using solar panels.
