The USM is a kind of new electrical motor which develops in recent 20 years, it broke through the traditional concept of electrical motor. It didn"t have the electromagnetism winding and the magnetic circuit, and it didn"t uses the mutually electromagnetism to transform the energy, moreover, the volume of electrical motor is small, the weight is light, the transfer efficiency is high. For it was so small, so light, and so thin, it have begun to use on automobile. But the usage of superconductivity electrical motor is still in the experimental stage at present. The main reason is that the super conductivity material has not realized the high temperature, but with the development of technical, the possibly uses of superconductivity electrical motor in the big horsepower like automobile generator and on actuation electrical motor causes the electrical machinery to be smaller in volume, lighter in weight, and higher in efficiency.
