I recently made a Large Scale FPV Car using two 775 DC motors in a dual configuration.
Based on the specifications for those motors on Banggood website, which shows a current consumption of less than 200mA, I used a L298n Motor Driver. But I burned it on the firsts tests. The current was to high for this board. So, I decided to use a BTS7960B motor driver, which claims to be rated up to 43A. It works fine but gets really warm… This fact made me think that the specifications for this motor on Banggood website can’t be correct.
In the PREVIOUS videos I showed you how to make two different tachometers based on two techniques: Laser & LED and Hall effect sensor & magnets. So, in this video, I took advantage of this experiment in conjunction with a power meter to show you that the specifications provided on Banggood website ARE NOT correct.
Have a look at the next video about 775 DC motor:
