Description
Technical field:
The utility model relates to a kind of motor, especially a kind of thermoelectric perpetual motion machine of preventing that can effectively prevent over-heat inside, guarantee normally to move, increase the service life, increase for a long time outputting power.
Background technology:
At present, known motor all is provided with seal casinghousing, and two ends, the housing left and right sides flexibly connect by bearing, axle sleeve etc. and electric machine main shaft, and rotor is fixed on the electric machine main shaft, and the stator on the inner walls of being fixed on is arranged outside rotor.After the energising, the electromagnetic force between stator and the rotor makes rotor rotation, promptly drives electric machine main shaft and rotates output kinetic energy.Because the rotor of existing motor all is cylindrical (solid), therefore, the heavy-duty motor that is applied on the main equipment such as electric car is all very heavy, and motor is under the prerequisite of equivalent weight, and its output torque is less; In the seal casinghousing of main is existing motor without any ventilation heat abstractor, the machine operation overlong time, the temperature in the seal casinghousing will raise, as not shutting down or externally being lowered the temperature, motor will burn because of overheated.For guaranteeing the long-time operate as normal of motor, cooling devices such as fan normally are set outside motor, not only take up room big, trouble is installed, cooling effect is poor, and fan is exposed outside, very easily too much breaks down because of dust.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, a kind of thermoelectric perpetual motion machine of preventing that can effectively prevent over-heat inside, guarantee normally to move, increase the service life, increase for a long time outputting power to be provided.
Technical solution of the present utility model is: a kind ofly prevented thermoelectric perpetual motion machine, housing 1 is arranged, be connected with electric machine main shaft 2 with two ends, housing 1 left and right sides, be fixed with rotor 3 on the electric machine main shaft 2, on housing 1 inwall, be fixed with stator 4, described rotor 3 is cylindric, joins by connecting plate 5 and electric machine main shaft 2, and through hole 6 is arranged on the connecting plate 5; Be provided with the fan 7 that is fixedly connected with electric machine main shaft 2 between housing 1 one ends and the rotor 3, the radius of gyration of fan 7 is less than rotor 3 radiuses; Be provided with the condenser pipe 9 that joins with compressor 8 between housing 1 other end and the rotor 3, wetly comb 10 on the housing 1 of condenser pipe 9 tops has condensed water row mouth 11 on the housing 1 of condenser pipe 9 belows, before water retaining separater 12 is positioned at the stator 4 of condensed water row mouthful 11 1 sides.
Described rotor 3 axially on be connected to fan back-up ring 13, fan 7 places in the fan back-up ring 13.
Described fan back-up ring 13 joins with the blade outer end of fan 7.
Be connected to drainage pipe 14 with described condensed water row mouth 11, drainage pipe 14 joins with draining valve 15.
Be provided with temperature sensor 16 on housing 1, temperature sensor 16 is by control circuit 17 control compressors 8.
Between housing 1 and stator 4, air duct 18 is arranged.
The utility model compared with prior art, its main distinction is the condenser pipe that fan is set in electric machine casing and joins with refrigerating plant, the rotor of motor is hollow cylindric.Fan rotates with electric machine main shaft, makes air communication cross the space of hollow, the condenser pipe of rotor, rotor and stator and forms circulation circuit, the heat cooling that circulating current produces stator, rotor at any time; Moisture in the housing etc. can be discharged by the moisture comb on the housing, the condensed water that is produced is by condensed water row mouthful discharge, can prevent motor overheating, guarantee the long-time operate as normal of motor, effectively prolong motor useful life, can avoid outside electric machine casing, being provided with simultaneously all disadvantages that heat sink brought such as fan.Because rotor is hollow cylindric, can with the prerequisite of prior art equivalent weight under, strengthen rotor radius, increase the output torque of motor, improve the operating efficiency of motor.The fan back-up ring that is provided with along rotor axis has the air-flow guide effect, further improves the circulating effect of air-flow; Set temperature sensor, control circuit can start compressor cooling when temperature upper limit, when lowest temperature, the control compressor quits work, and both can economize on electricity, and can prevent freezing motor again.
