These are simple DC motors, just as the title states. These are a straight DC motor with no gearbox whatsoever.
We offer these simple motors in assorted power ranges at 12VDC motors which are compatible with our range of DC Speed controllers.
With no gearing, these universal motors are designed for scooters or e-bikes using belts and chains (with varying size sprockets) to create high torque or medium torque with higher speeds!
While primarily designed for scooter or go-kart use, these are a popular range for hobbyists and inventors.
While these are low cost motors, there’s nothing cheap about the quality. They are simply motors that are made in such large quantities that they can be produced with a low price point.
The are manufactured in bulk, so while its expensive to get changes made (quantity must be purchased) the stock motor is low cost due to its availability and widespread use.
