Description
Technical field
The utility model relates to technical field of generators more particularly to a kind of cooling structures of high-speed permanent magnetic generator.
Background technique
Permanent magnetism high-speed engine has high-efficient, compact-sized, small in size advantage.Since permanent magnetism high-speed engine is run
When revolving speed section it is wide and the high permanent magnet of temperature has demagnetization risk, motor radiating becomes one of the biggest problem of Design of PM Motor,
Major part magneto uses air-cooled at present, wherein air-cooled (add blade in motor axle portion tail end, with motor shaft including commonly air-cooled
Portion rotates ventilating and cooling, the disadvantage is that noise is big, cooling effect is poor), air blast cooling is (in the independently installed cooling wind in motor tail portion
Machine, forced ventilation are cooling, control at high cost all the way and greatly improve motor overall failure rate the disadvantage is that more), in addition also
Water-cooling pattern, good cooling results, but one need to increase water pump, lead to increased costs, secondly volume increases, are unfavorable for installing.
Utility model content
The purpose of this utility model is to provide a kind of type of cooling is simpler, power generation machining material can be effectively saved
Material reduces electrical fault rate, improves the cooling structure of the high-speed permanent magnetic generator of motor global reliability.
The technical solution of the utility model is: a kind of cooling structure of high-speed permanent magnetic generator comprising: rotor, stator,
Bearing, bearing block, electric machine casing, diversion seat and water conservancy diversion outer cover, the both ends of the rotor pass through respectively bearing be mounted on it is described
On bearing block and the diversion seat, the stator is mounted on the electric machine casing, and the water conservancy diversion outer cover is mounted on the motor
On shell, and multiple cavities a, the electric machine casing and the axis are formed between the water conservancy diversion outer cover and the electric machine casing
It holds and is formed with cavity b between seat, be connected between the cavity a and the cavity b, between the electric machine casing and the diversion seat
It is formed with cavity d, there is axially extending bore c, the cavity b to be connected to by through-hole c with the cavity d on the stator.
Further, centrifugal impeller is installed, one end of the rotor connects the centrifugal impeller in the diversion seat.
Further, the water conservancy diversion outer cover inner wall is equipped with multiple fins, and cavity a is formed between multiple fins.
Further, the cavity a and cavity d is connected to outside.
In conclusion the utility model has the beneficial effects that: the cooling knot of the high-speed permanent magnetic generator of the utility model
The structure type of cooling is simpler, is convenient for generator whole design；Since such type of cooling is just as the revolving speed of generator is high, power
Density is big, and outer dimension is much smaller than the conventional rotating speed generator with power grade, therefore can effectively save generator and add
Work material；High reliablity, due to using on centrifugal impeller fixed rotating shaft, part is few and technology maturation, reduces electrical fault rate,
Improve the reliability of motor entirety.
The utility model is described in more detail below by embodiment.
Detailed description of the invention
Fig. 1 is the side view of the cooling structure of the high-speed permanent magnetic generator of the utility model.

The both ends of son 2 pass through bearing 7 and 8 respectively and are mounted on the bearing block 9 and the diversion seat 6, and the stator 3 is mounted on described
On electric machine casing 4, the water conservancy diversion outer cover 5 is mounted on the electric machine casing 4, and the water conservancy diversion outer cover 5 and the motor casing
Be formed with multiple cavities a between body 4, be formed with cavity b between the electric machine casing 4 and the bearing block 9, the cavity a and
It is connected between the cavity b, cavity d is formed between the electric machine casing 4 and the diversion seat 6, there is axis on the stator
To through-hole c, the cavity b is connected to by through-hole c with the cavity d.
Centrifugal impeller 1 is installed, one end of the rotor 2 connects the centrifugal impeller 1 in the diversion seat.The water conservancy diversion
The inner wall of outer cover 5 is equipped with multiple fins 10, forms cavity a between multiple fins 10, that is, has the inner wall and wing of water conservancy diversion outer cover 5
Piece and electric machine casing 4 define cavity a, the cavity a and the cavity d and are connected to outside.
The working principle of the utility model is: rotor 2 is rotated by shaft rotation drive centrifugal impeller 1 first, it is centrifuged leaf
Taking turns 1 high speed rotation generation centrifugal force causes cavity d to form negative pressure, to make cool ambient air enter cavity b from cavity a, i.e.,
Air is passed into cavity b from the cavity a sucking of fin between water conservancy diversion outer cover and shell, then by stator 3,2 air gaps of rotor with
Through-hole c is then exhausted from after entering cavity d, is achieved the purpose that the cooling motor of forced ventilation with this, is realized the cooling motor of forced ventilation
Improve motor service life.
The structure that the cooling structure of the high-speed permanent magnetic generator of the utility model is not limited to the above embodiments can carry out more
Kind modification.In short, being both fallen in the scope of the utility model in all improvement not departed within the scope of the spirit of the present invention.
