Principle of Adiabatic Demagnetization. The principle of the adiabatic demagnetization process is applicable to magneto-caloric materials. The principle follows that when these materials are placed in a magnetic field, they start heating up. However, when removed from the magnetic field, then they cool down. The principle of adiabatic
Due to the narrow working space of an in-wheel motor, the heat generated by the motor loss is difficult to dissipate. This makes it easier for the in-wheel motor to demagnetize the permanent magnet due to the mega-temperature, which affects the output efficiency. To solve this problem, an external rotor hub motor is studied. First, in accordance with the theory of

A heat switch does for heat what an electrical switch does for electricity. When you want the heat to be able to flow, you turn the heat switch on. When you want to block the flow of heat, you turn the heat switch off. When enough heat has flowed to the coolant bath, the operator turns off the heat switch, then reduces the magnetic field.
