摘要
The devices have RE magnets incorporated with electromagnet (EM) used for short stroke and block-shaped brakes. The application of RE magnets results in small volume, light weight, easy installment and maintenance, coil protection, rapid response, large moment, long service life and low production cost. More important is that the devices can save over 99% energy in comparison with the traditional ones and could replace the relays in shop cranes, gantry cranes and other lifting machineries in service in such industries as metallurgy, mining, chemical engineering, port and construction.Market: sufficient in China and good potential in the world.
