The use of dc motor controller details analysis

Dc motor controller in use process, what are the details we need to pay attention to? Below small make up to explain it. 1. If the product has no special instructions, dc motor controller cannot reverse system running under the rated voltage, because it will cause the phenomenon of demagnetization. 2. On magnetic circuit of the dc motor controller for magnetic short circuit protection, because the current is too large, the temperature change and the factors such as magnetic circuit open circuit when disassembling, can cause demagnetization. 3. When change the brush, electric carbon dust around to clean up, and alcohol and gasoline to clean the commutator. Above is the details of the dc motor controller using problem, you know.
