Hoprio 4 Inch Brushless Angle Grinder Machine（220V S1M-100YE2）
Dc motor controller which details need to be careful
No matter what product in use have some details need to be aware of, dc motor controller is an exception. To dc motor controller to better use, need to use the details below. 1. If there is no special requirements of product under the rated voltage of dc motor controller is not allowed to run the reverse connection system. Because once to run the reverse system, can cause permanent magnet demagnetization, if don't want to run in this way, then add current limiting resistor to limit current is too large. 2. Note to avoid excessive current, temperature and magnetic circuit open circuit when disassembling cause permanent magnet demagnetization, especially aluminum nickel and cobalt permanent magnet motor controller, when disassembling the need for magnetic short circuit protection, avoid to cause demagnetization. 3. When the brush replacement, need to on the surrounding electrical carbon dust to clean up, then use alcohol, gasoline to clean the commutator. At the same time should pay attention to when using the new brush no-load running in. More than the use of dc motor controller details at this point, hope to be of help.
