Detail decides success or failure, when using dc motor controller is also very the attention to detail. Below small make up to say with you is some use dc motor controller in detail. 1. If you use dc motor controller products without special instructions, so under rated voltage when using dc motor controller does not allow the system to run, or it will lead to permanent magnet demagnetization. If must be operated by this way, then use it in order to make everyone safe, need to add current-limiting resistance, prevent excessive current. 2. Caused by permanent magnet demagnetization current is too large, the temperature change and reasons when disassembling magnetic circuit open circuit and so on, so should pay attention to when using. For instance, when disassembling of permanent magnet magnetic circuit completes the magnetic short circuit protection, in order to avoid again after demagnetization of magnetization. 3. When change the brush to clean up, such as electric carbon dust around, and use of alcohol, gasoline and other cleaning commutator. At the same time for no-load running in new brush first. The above is the use of dc motor controller details, you know.
