Embodiment 1
[0031] A method for sub-regional cooling between internal cooling and external cooling of rotor magnetic poles. The cooling gas flows into the channel between the two magnetic pole coils 1 through the ventilation partition device 6 on the air inlet end of the two magnetic pole coils 1 to form an external cooling ventilation air path, and The outside of the pole coil 1 is cooled, and at the same time the cooling gas flows into the inside of the pole coil 1 through the gap between the pole core 2 and the pole coil 1, forming an internal cooling ventilation air path, and cooling the inside of the pole coil 1, and then from the pole coil 1 internally flows into the channel between the two magnetic pole coils 1, and the ventilation partition device 6 separates the external cooling ventilation air path and the internal cooling ventilation air path flowing into the channel from each other.
[0032] This embodiment is the most basic implementation mode. Using this method, the cooling g...
