Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a novel permanent magnet power generation device. Background technique [0002] A permanent magnet generator refers to a power generation device that converts mechanical energy converted from thermal energy into electrical energy. In today's DC motors, the excitation method that uses DC current to generate the main pole magnetic field is called current excitation; if permanent magnets are used instead of current excitation to generate the main pole magnetic field, this type of motor is called a permanent magnet motor. The permanent magnet generator has the advantages of small size, low loss, high efficiency, etc. Today, when energy saving and environmental protection are paid more and more attention, its research is very necessary. Brushless can be achieved in many cases, so it is mostly used in small and micro motors. When using variable frequency power supp...
