Coil is placed on outside pole core, and pole coil is formed by multilayer current-carrying row's stacking, has insulating materials between current-carrying row.The current-carrying row
Also referred to as bus or busbar, are to hold a kind of current-carrying conductor, the exciting current for carrying salient pole synchronous electric machine, mutual insulating heap
Passed in folded current-carrying row after electric current, similar to spiral coil, magnetic field can be produced, and pole core then will be magnetic field-enhanced,
Pole core plays a supportive role to pole coil simultaneously.The normally gaseous cooling of the magnetic pole type of cooling of salient-pole machine.Rotor branch
Frame produces blast head in rotary course, cooling gas is blown into magnetic pole interpolar through yoke, cooling gas is flowing through magnetic pole interpolar
During air gap and stator core air duct, the surface that pole coil is in interpolar can be skimmed over, cooling gas is in magnetic pole
With pole coil heat exchange occurs for coil surface, so as to cool down pole coil.Particularly, high rotating speed unit is general above and below yoke
Two ends are equipped with fan blade, under fan blade effect, form axially cooling wind, and cooling wind enters magnetic pole interpolar, pole is in pole coil
Between surface cooled down.The above-mentioned type of cooling, the surface that pole coil participates in heat exchange only has in interpolar along magnetic pole current-carrying
The fraction of thickness direction is arranged, cooling effect is unsatisfactory.
