Problems solved by technology

Although this superconducting synchronous motor has obvious advantages compared with conventional motors, there are still some disadvantages. The most obvious disadvantage is that due to the superconducting coils wound with high-temperature superconducting wires in the rotor, in order to cool these coils, it is necessary Adding a thermal insulation layer to the rotor, and passing the refrigerant into the rotor while introducing the current into the rotor, this complex rotor structure makes the motor larger in size and higher in cooling power, and will reduce the safety and reliability of the motor operation. stability
