Abstract

a presente invenção refere-se a uma máquina elétrica giratória de uma modalidade que tem um alojamento, um estator, um rotor e uma ventoinha. o alojamento tem uma seção cilíndrica. o estator tem um núcleo de estator, que é fixado pela carcaça do motor, e uma bobina de estator, que é disposta no núcleo de estator. o rotor tem um eixo giratório, que é disposto no lado radialmente interno do estator de maneira girável com relação ao estator, e um núcleo de rotor, que é encaixado e fixado no eixo giratório. a ventoinha é disposta no eixo giratório e sopra, em um estado de pressão positiva, ar tirado do lado de fora para o núcleo de estator e o núcleo de rotor, a fim de resfriar o núcleo de estator e o núcleo de rotor. além disso, a seção cilíndrica é dotada de um orifício de descarga de poeira em uma parte mais perto do núcleo de estator do que a parte mediana entre a borda circunferencial externa da ventoinha e o núcleo de estator.The present invention relates to a rotary electric machine of one embodiment having a housing, a stator, a rotor and a fan. The housing has a cylindrical section. The stator has a stator core, which is fixed by the motor housing, and a stator coil, which is disposed on the stator core. the rotor has a rotary shaft which is rotatably disposed on the radially inner side of the stator with respect to the stator, and a rotor core which is engaged and fixed to the rotary shaft. The fan is arranged on the rotary shaft and blows, in a positive pressure state, air drawn from outside to the stator core and rotor core to cool the stator core and rotor core. In addition, the cylindrical section is provided with a dust discharge port at a part closer to the stator core than the median part between the outer circumferential edge of the fan and the stator core.
