No matter what the product is in use in detail are very heavy.
Below we said about the use of dc motor controller in detail.
If the product has no special instructions, dc motor controller in use cannot reverse system running under the rated voltage.
Because it is easy to cause the demagnetization phenomenon.
Due to the large current of dc motor controller, temperature change, when assembling and disassembling magnetic circuit open circuit and other reasons, lead to demagnetization.
So the magnetic circuit of the magnetic short circuit protection.
Replacement brush, electric carbon dust around to clean up, clean with alcohol, gasoline commutator.
Above is the use of dc motor controller details analysis, hope to help you.
