In figure：Trunnion 1；Induced duct 2；Spiral case 3；Bearing 4；Motor stator 5；Electric machine casing 6；Main shaft 7；Impeller 8；Air blower inlet air
Mouth 9；Enter air holes 10；Blower outlet 11.
Embodiment：
With reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, including electric machine casing 6, the spiral case 3 for being placed in the upper end of electric machine casing 6, main shaft 7 is installed in electric machine casing 6
With motor stator 5, it is provided with impeller 8, bearing 4, spiral case 3 on main shaft 7 and offers air blower air intake vent 9, the air blower of spiral case 3
Trunnion 1 is installed on the position of air intake vent 9, the osculum end of trunnion 1 by induced duct 2 with being connected inside electric machine casing 6, motor casing
Offered on body 6 be in communication with the outside enter air holes 10, the air inlet of induced duct 2 is arranged on the corresponding motor in the one end of motor stator 5
On housing 6, enter air holes 10 and be opened on the corresponding electric machine casing 6 of the other end of motor stator 5, make the inside of electric machine casing 6 and the external world
Connection,
The inside of trunnion 1 is entered air holes 10 and drum by the system through what is opened up on induced duct 2, the inside of electric machine casing 6 and electric machine casing 6
The outside of blower motor housing 6 forms the cooling air-flow air channel of connection, when air blower is run, and air blower air intake vent 9 is in trunnion 1
Put to form high velocity air, by the reducing tubular construction of trunnion 1, increase the internal gas flow velocity of trunnion 1, pressure reduction, and then shape
Into negative pressure, enter the position of air holes 10 for atmospheric pressure on blower motor housing 6, be internally formed pressure difference in cooling air-flow air channel, enter
And air-flow is formed, so as to need the heating element cooled to cool down air blower inside, induced duct 2 can install one or many
It is individual.
The device of the trunnion 1 formation negative pressure installed additional using air blower air intake vent 9, utilizes induced duct 2 and the inside phase of electric machine casing 6
Connection, while being opened up on electric machine casing 6 into air holes 10, when motor impeller 8 rotates at a high speed, in air blower air intake vent 9
Negative pressure is formed, and electric machine casing 6 is individually opened up into being atmospheric pressure at air holes 10, therefore is internally formed air-flow in electric machine casing 6, band
The dynamic extraneous air of electric machine casing 6 enters inside electric machine casing 6 through entering air holes 10, enters air blower air intake vent 9 through induced duct 2, with
The mixing of air blower primary air is discharged after being compressed through impeller 8 by air blower exhaust vent 11, and this cyclic process is realized to air blower
The rapid cooling of internal electrical components, cooling effectiveness is high, compared with traditional water cooling and motor coaxle fan coolling mode, has
The characteristics of simple in construction, low-risk, low energy consumption.
Preferable feasible embodiment of the invention is the foregoing is only, not thereby limits to the interest field of the present invention,
Within the equivalence changes that all utilization description of the invention and its accompanying drawing content are made, the interest field for being both contained in the present invention.
