Abstract
A permanent magnet disk-type electric machine with internal air-duct adds a centrifugal fan on a rotary part. And it makes individual structural parts of a motor form air ducts between them to generate an internal recycling inside the motor in order to achieve the goal of reducing the heat spot of the motor and raising the temperature of the motor. It can eliminate the heat spot of the motor and reduce temperature rise of the motor by 5 DEG C-10 DEG C after adopting the utility model.
Description
The utility model is a kind of permanent-magnet disk direct current machine, by the fan in the accompanying drawing (7), and axle (8), end cap (9), magnet steel (10), casing (11), armature winding (12), yoke (13), commutator (14), and the inner ventilation road that (1)～(6) are formed constitutes.
In existing disc type electric machine, be the full-closed structure of no inner ventilation, thereby there is the tangible temperature difference in each heating part of motor, particularly partly temperature is the highest for the armature winding internal diameter.
The purpose of this utility model is, designs a kind of motor internal ventilating system, makes gas produce circulation of air flow at motor internal, with the point of crossing of elimination rotor, and electric machine temperature rise is descended.
The purpose of this utility model is to realize (seeing accompanying drawing) like this, on the rotating parts of motor, increase the centrifugal fan (7) that produces blast, fan cooperates part to have fresh air inlet (6) with axle, the high pressure draught that is produced by fan blade during the fan rotation blows out air-flow by air outlet (1), passage (2) through the formation of the gap between armature winding lower surface and magnet steel and the end cap, passage (3) between the outer garden of casing and armature winding, and form passage (4) between casing and the yoke, enter fan fresh air inlet (6) by air inlet duct (5) then and finish circulation of air flow, rotor internal diameter part heat is sent.Pass in the cooling air by casing and end cap and to go.
The key of ventilating system is.Design a kind of fan that can send certain air quantity simple in structure, requisite another condition is that the vent channel that makes motor internal have an air feed stream to pass through makes air-flow constantly circulate at motor internal simultaneously.
Behind the ventilation circulation system, eliminated the motor overheating point in adopting, and temperature rise is descended 5 ℃～10 ℃.
Be an embodiment below, at ZPY---in the 300 type permanent-magnet disk direct current machines, adopted the centrifugal fan of aluminium alloy casting, fan puffs away stream through air duct 1,2,3,4,5, is returned by hole 6, the ventilating system of circulation in forming.Make motor overheating point (armature winding is by the fan place) temperature descend 7 ℃ of the corresponding declines of electric machine temperature rise.
Claims (2)
1, a kind of permanent magnet disc motor with inner vent gutter, by fan (7), axle (8), end cap (9), magnet steel (10), casing (11).Armature winding (12), magnet steel (13), commutator (14) and the inner ventilation road formation of forming by (1)～(6), it is characterized in that having a centrifugal fan (7) that produces blast, and the inner loop ventilating system that forms by (1)～(6), high pressure draught is through fan outlet (1), flow into the passage (2) that the gap between armature winding lower surface and magnet steel and the end cap forms, passage (3) between the outer garden of casing and armature winding, and passage (4) between casing and the yoke (13), enter fan fresh air inlet (6) by air inlet duct (5) then, finish circulation of air flow.
2, according to the described permanent magnet disc motor of claim 1, it is characterized in that fan is formed by aluminium alloy compression casting with interior air duct, also can be by other metal or nonmetal making.
