摘要
An electric motor normally does not assume that it will be operated above its rated output. This is because it is easily understood what happens when the electric motor is always operated with an overload. The present invention aims to realize a coreless rotating electrical machine that always operates at a load exceeding a rated load, a driving method thereof, and a driving system including the same, and more specifically, an ironless cylindrical coil that can be energized. An air gap including an air gap between a stator composed of a lid-type mount that fixes the end face of the rotor and a rotor having a plurality of magnets arranged on the inner peripheral surface of a cylindrical or cup-type mount that is rotatably opposed to the lid-type mount When operating at a load exceeding the rating in a coreless rotating electrical machine that forms a cylinder, the refrigerant liquid is supplied to the gap including the air gap, and the cylindrical coil that generates heat vaporizes the refrigerant liquid, and the latent heat of vaporization of the refrigerant liquid causes the cylinder to Operate with a load exceeding the rating by cooling the coil and adjusting the supply amount of refrigerant liquid so that the cylindrical coil does not exceed the allowable upper limit temperature during rated operation. No core rotating electric machine, and a driving method thereof, and, as a drive system including the same, have been realized.
