Rare earth permanent magnet brush dc motor is most used on the plane
brush dc motor is still in China at present the most used on the plane
brush dc motor is still in China at present the most used on the plane. The motor while there are some inherent shortcomings, but because of its cost is relatively low, the craft is mature, feature is good, and continues to play an important role in some system, and constantly seeks technological progress. The rare earth permanent magnet excitation can effectively improve the power density; Use a variety of redundancy, form to improve fault tolerance; By multielement alloy metal brush and commutator commutation performance, prolong life; Using hollow cup armature structure reduce the moment of inertia, etc.

"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
