The brush volume is small and the use time is relatively short; if the reverse speed limit function is performed again, the motor parameters, winding, poor process design, and second brush wear will be accelerated. To this end, many manufacturers and people of insight are constantly developing and researching the above problems, but so far there are no better ways to improve them.

The lower cost brush holder rotates forward and reverse to the device.
