Description
Technical field
The present invention relates to a kind of sealing cooling structure desk permanent-magnet motor.
Background technology
That the desk permanent-magnet motor has is simple in structure, volume is little, in light weight, characteristics that efficient is high, and it comprises stator core, in stator core, is provided with stator winding, is provided with rotor core in the stator winding inboard, in rotor core, is provided with the rotor that has permanent magnet.Mostly existing desk permanent-magnet motor is Open architecture, adopts natural air cooled mode to cool off, and the heat that its winding and stator core produce dispels the heat through stator core, end cap.This radiating mode is compared with the motor of radial structure has following defective: 1, Open architecture is prone to make permanent magnet to be corroded, and shortens the useful life of desk permanent-magnet motor.2, natural air cooled radiating mode need to ventilate, shady and cool, dry environment, and desk permanent-magnet motor arrangement position is difficult to satisfy above environmental requirement.3, the area of dissipation of desk permanent-magnet motor is far smaller than the motor of radial structure, and radiating rate is slow, and winding temperature rise is high, has limited the lifting of desk permanent-magnet motor power (output) density.
For addressing the aforementioned drawbacks; Disclose a kind of fluid-cooled concentrated magnetic desk permanent-magnet torque motor that has among the CN102185392A, this motor magnetic isolation plate outside is provided with the mobile chamber of cooling liquid, during work; In cooling liquid flows the chamber, inject cooling fluid, be used to cool off winding.The defective of this type of cooling is: 1, the fluid-cooled active area is little, only can cool off winding, and the each several part temperature is uneven in the desk permanent-magnet motor, is prone to cause local overheating, burns motor.2, coolant flow chamber cavity capacity is big, and the new cooling fluid of injecting is mixed in the coolant flow chamber, and temperature raises, and causes having a narrow range of temperature between cooling fluid and the winding, and cooling effect is poor.
Summary of the invention
The technical problem that the present invention will solve provides a kind of rapid heat dissipation, good cooling results, and power density is high, long service life, each part temperatures is even, the sealing cooling structure desk permanent-magnet motor that can not burnt because of local overheating.
The present invention is achieved in that
A kind of sealing cooling structure desk permanent-magnet motor; Comprise casing; Be located at driving side end cap, the non-drive side end cap of casing both sides, be respectively equipped with axis hole, on driving side end cap, non-drive side end cap, be separately installed with winding at driving side end cap, non-drive side end cap center; Between two axis holes, be provided with rotating shaft; Its special character is: be respectively equipped with helical form end cap water channel I, end cap water channel II in driving side end cap, the non-drive side end cap, said end cap water channel I outlet, end cap water channel II inlet lay respectively at driving side end cap and non-drive side end cap outer rim, on the driving side end cap, are provided with the water inlet that communicates with end cap water channel I inlet; On the non-drive side end cap, be provided with the delivery port that communicates with the outlet of end cap water channel II, the outlet of end cap water channel I, end cap water channel II inlet are communicated with through straight water channel in many machines that circumferentially are uniformly distributed with.
The rotation direction of said end cap water channel I, end cap water channel II is opposite, to improve cooling effectiveness.
Said water inlet, delivery port are near axis hole.
The rotation direction of said end cap water channel I is clockwise, and the rotation direction of said end cap water channel II is counterclockwise, to reach optimum cooling effect.
Straight water channel two ends to reduce the flow resistance of cooling water, are improved cooling effectiveness through collecting and distributing pipe parallel connection in the said machine.
Straight water channel is the bent angle shape with the junction of collecting and distributing pipe in the said machine, to reduce cooling water by the resistance during water channel directly in the collecting and distributing pipe entering machine.
The invention has the beneficial effects as follows:
1, adopts water-cooling pattern, and pass through straight water channel, end cap water channel II in end cap water channel I, the machine, do not take space in the machine through cooling water; Under the situation that does not influence the work of desk permanent-magnet motor; Increased area of dissipation to greatest extent, radiating rate is fast, and power density is high.
2, this desk permanent-magnet motor is an enclosed construction, owing to adopt water-cooling pattern, extraneous environmental aspect is little to the cooling effect influence, and the installation site does not receive environmental limitations; And airborne corrosive substance is difficult to contact permanent magnet, therefore, has prolonged the useful life of this desk permanent-magnet motor.
3, the desk permanent-magnet motor interior is from driving the side direction non-drive side; Its temperature reduces gradually; Because through straight water channel, end cap water channel II in end cap water channel I, the machine, its temperature gets into gradually from water inlet and raises cooling water, and is opposite with desk permanent-magnet motor interior Temperature Distribution successively; Effectively make the temperature equalization of motor components, avoid burning out motor because of local overheating.
4, because the end cap water channel is a helical form; Straight water channel is straight shape in the machine, so cooling water is longer in the end cap water channel time of staying, and the straight water channel time of staying is shorter in machine; Because the main heating parts of desk permanent-magnet motor are the driving side winding; When cooling water has just got into and the temperature difference of driving side winding enough big, cooling water is long in the end cap part time of staying, can fully carry out heat exchange; When in the cooling water entering machine during straight water channel, its temperature raises, and with having a narrow range of temperature of desk permanent-magnet motor interior air, because the cooling water time of staying is short, still can guarantee cooling effect; When cooling water got into the non-drive side end cap, though the temperature of cooling water further raises but still is lower than the non-drive side winding temperature, cooling water still can be the cooling of non-drive side winding through the helical form end cap water channel II with big film-cooled heat; This sealing cooling structure desk permanent-magnet electric motor structure is reasonable in design, makes full use of cooling water, good cooling results, energy savings.
