Description
Technical field
It the utility model is related to monophase machine technical field, and in particular to a kind of with cylindrical annular centrifugation blade structure
Motor.
Background technology
Centrifugation blade is the principle that potential energy is converted to according to kinetic energy, and the impeller using high speed rotation accelerates gas, then
Slow down, change flow direction, kinetic energy is converted into potential energy (pressure), centrifugation blade is not when in use if be separately provided wind path track
(being usually additional fan housing), the wind of blowout is dissipated to surrounding, smaller for motor cooling effect, can only play drive air
The effect of flowing, and can not be directly by the wind of high speed to motor case fin, so typically increasing fan housing to change wind
Direction；Although additional fan housing changes wind direction, but wind energy loss is too big, and motor manufacturing cost can rise.
Utility model content
In order to solve the above technical problems, to be to provide a kind of loss of wind energy small for the purpose of this utility model, good heat dissipation effect
Motor with cylindrical annular centrifugation blade structure.
The technical solution of the utility model is as follows：
A kind of motor with cylindrical annular centrifugation blade structure, including fan housing (1), blade structure (2), rear end cap (3),
Terminal box (4), casing (5), stator module (6), drive end bearing bracket (7), rotating shaft (8) and rotor (9), the rotor (9) are sleeved on institute
State centre position on the outside of rotating shaft (8), the stator module (6) is arranged on the outside of the rotor (9), rotating shaft (8) front end and
It is arranged on respectively by bearing (10) on the drive end bearing bracket (7) and rear end cap (3) close to back-end location, after the rotating shaft (8)
End is connected with the blade structure (2)；The fan housing (1) covers on the blade structure (2) outside；The casing (5) is arranged on institute
State on the outside of stator module (6), be fixed together by screw and the drive end bearing bracket (7), rear end cap (3)；The terminal box (4) sets
Put in the outside side of the casing (5)；
The blade structure (2) is centrifugal fan, and with circle ring, centre is provided with joint portion (21), the knot
Blade (23) is set on the outside of conjunction portion (21), cylindrical ring portion (22) is set on the outside of the blade (23).
Further, joint portion (21) and the rear end of the rotating shaft (8) are connected through a screw thread in the blade structure (2).
Further, the cylindrical ring portion (22) is the cyclic structure of middle protrusion, and section is splayed configuration, the protuberance
Divide the side for being positioned close to the fan housing (1).
Further, the blade (23) centered on the center of circle of the joint portion (21) annular array in the combination
The outside in portion (21), the number of the blade (23) is 6 or 8.
By such scheme, the utility model at least has advantages below：
The utility model simply changes wind direction by setting structure with cylindrical annular blade structure, by blowout
Wind is gathered, and blows to motor case fin, improves motor radiating cooling effect, reduces wind energy loss and the abrasion to fan housing,
Reduce the cost of motor.
