These motors are simple DC Motors featuring gears for the shaft for obtaining the optimal performance characteristics. They are known as Center Shaft DC Geared Motors because their shaft extends through the center of their gearbox assembly. These standard size DC Motors are very easy to use. Also, you don’t have to spend a lot of money to control motors with an Arduino or compatible board. TheL298N H-bridge module with onboard voltage regulator motor driver can be used with this motor that has a voltage of between 5 and 35V DC. This DC Motor – 500RPM – 12Volts can be used in all-terrain robots and a variety of robotic applications. These motors have a 3 mm threaded drill hole in the middle of the shaft thus making it simple to connect it to the wheels or any other mechanical assembly. Nut and threads on the shaft to easily connect and internally threaded shaft for easily connecting it to the wheels. These DC Geared motors with robust metal/Plastic gearbox for heavy-duty applications, available in the wide RPM range(Check the list below) and ideally suited for robotics and industrial applications.
