The world's first permanent magnet motor driven shield machine first launched in Wuhan

Now the railway construction group has successfully maintained a week to develop a new product or a new achievement miracle. 8 3, the world's first use of shield machine permanent magnet motor drive is developed by the railway construction heavy industry success in Wuhan Metro Line 27, which marks the group is an industry leader in the energy saving technology of shield machine.

Railway Construction Group adhere to the "customer satisfaction research, only the value of" development philosophy, continuous improvement, the shield of painstaking research, finally made a permanent magnet motor drive results. It is understood that permanent magnet motor driven shield machine has the characteristics of "energy saving, environmental protection and high efficiency", "simplified driving structure", "saving in shield space", "simple and stable motor control", "high starting torque of permanent magnet synchronous motor" and so on.

"Energy conservation and environmental protection" is the absolute principle". Permanent magnet synchronous motor has high efficiency, and its energy efficiency level is higher than IE3 and GB 2. Assume that the permanent magnet synchronous motor with high power efficiency than asynchronous motor 3%, cutter according to 1000kW power meter, electricity per hour for permanent magnet synchronous motor 30, a day by the cutter of 8 hours of work, every day is boring machine, can save electricity 240 degrees, equivalent to a day can save 500 yuan.

For enterprises, the development of a new product, a new technology is not easy, should not only consider the work efficiency, but also consider the factors of green environmental protection, security and other aspects, but if the new products once developed, its influence and the profit is very considerable.
