The original drive used an 18V battery, and the over-discharge protection was inside the original battery. The actual test of the brushless drive can support a wide voltage range of 10-20V. The definition of wiring has been researched. You can change the speed of the potentiometer. supports forward and reverse rotation. The Hall positioning is offset by a certain angle. Otherwise, there is an error in the no-load current of forward and reverse operation. For the wiring definition, see the introduction box . . It is suitable for various occasions and has strong compatibility. At the same time, it protects the motor and drive plate to be more stable and lasting. Using brushless motor technology, the operation is more stable and quiet, the efficiency is higher, and the service life is longer. It is small and easy to install, does not occupy space, and is convenient for users to use. 18V20V brushless motor driver board It can be widely used in smart home equipment, aircraft models, electric tools, industrial automation equipment and other fields.
