Breakthrough in new rare earth permanent magnet motor technology

Recently, the "New Rare Earth Permanent Magnet Motor Design and Integration Technology Research" project has achieved breakthroughs. This project successfully developed a 2.2 kW ironless motor and a 5 kW transverse flux motor. The developed iron-free motor efficiency reached 89.8%, 11.8% higher than the Y2 series asynchronous motor of the same specification, the power density increased by 103%, and the power density of the transverse flux motor doubled that of the ordinary motor. The two types of permanent magnet AC servo motors developed by this subject can be widely used in CNC machine tools, robots, electric vehicles, elevators, household appliances and other occasions.
At present, some of the results of this project have been transferred to Dalian Machine Tool Group Co., Ltd. and Zhejiang Speed ​​Control Motor Co., Ltd. After the company receives the production, it can quickly form a production scale and realize export.

When you drive the car on the road,a secure fit for the wheels on your vehicle is most important. A lug nut or wheel nut is a fastener which are important to secure a wheel onto your vehicle. You should install the Wheel Nuts properly and tightly.Otherwise, the wheels can gradually move out of alignment and eventually detach from their axles. Anyway, Lug Nuts or Wheel Nuts can help keep your wheels firmly attached to your car at all times.

Loose or missing the Wheel Nuts will cause uneven pressure on the wheel hub and contribute to premature wear of the wheel bearings. And an uneven pressure will occur when your vehicle turns the corners, brakes or ramps up to a high speed.

Wheel Nuts are key to the entire wheel mounting system, to work properly and safely, means that the wheels must make full contact with and fit flat against the mating surface of the hub.
