Description
Technical Field
The utility model relates to a generator technical field, concretely relates to water-cooling permanent magnet generator.
Background
The permanent magnet generator is a power generation device which converts mechanical energy converted from thermal energy into electric energy. In the current dc motor, an excitation method of generating a main pole magnetic field by a dc current is called current excitation; if permanent magnets are used instead of current excitation to produce the main pole field, such machines are referred to as permanent magnet motors. Brushless motors are used in many cases, and therefore, they are used in small-sized and miniature motors. When the variable frequency power supply is adopted for power supply, the permanent magnet motor can also be used for a speed-regulating transmission system. Permanent magnet motors have been widely used in various fields such as household appliances, medical instruments, automobiles, aviation, national defense and the like with the continuous improvement and perfection of the performance of permanent magnet materials. The permanent magnet motor has the disadvantage that if the permanent magnet motor is not used properly, under the action of armature reaction generated by impact current or violent mechanical vibration, irreversible demagnetization can be generated, so that the performance of the motor is reduced, and the motor can not be used.
