Description
Technical field
The utility model relates to a kind of motor.
Background technology
At present, most motors all comprise rotating shaft, rotor assembly, stator module, casing and end cap, rotor assembly is arranged in rotating shaft, stator module and casing are installed together and are nested in rotor assembly outside, and end cap is arranged on casing two ends, and shaft support is on the bearing of two end cap, but the installation of this electric machine structure comparatively bothers, efficiency of assembling is lower, causes cost of labor higher, lacks the market competitiveness.Meanwhile, because vibrations easily get loose, there is larger potential safety hazard in end cap in motor operation course.And waterproof effect is undesirable, rainwater easily flow into motor internal from electric motor end cap and causes rotor assembly or stator module to damage, and have a strong impact on the normal operation of motor, and replacement cost is high.
Utility model content
Main purpose of the present utility model is to provide a kind of motor, and this electric machine structure is simple, easy for installation, firm, and the good water-proof effect of motor, and reliability is high.
Above-mentioned purpose is achieved by the following technical solution:
A kind of motor, comprise rotating shaft, rotor assembly, stator module, casing and end cap, rotor assembly is arranged in rotating shaft, stator module and casing are installed together and are nested in rotor assembly outside, end cap is arranged on casing two ends, shaft support is on the bearing of two end cap, it is characterized in that: also comprise mounting screw and nut, at casing both ends, stretch out outward annular flange, end cap is arranged on the end of casing and is bearing on the end face of annular flange, and mounting screw coordinates end cap and casing are installed together with nut check through end cap and annular flange.
Above technical scheme can be further improved by following measures:
Between end cap described above and annular flange, be provided with annular water proof ring.
Casing described above is one drawing and forming.
In the middle of end cap described above, toward inner side, stretch out bearing chamber, in bearing chamber the inside, bearing is installed, shaft support is on bearing.
Bearing outside described above is provided with insulating barrier with bearing chamber inwall.
Insulating barrier described above is that injection moulding is arranged on bearing outside.
End cap inwall described above is provided with temperature sensor.
Each technical measures can be selected a use above, and yet use capable of being combined, as long as that does not form conflict between levying.
The utility model compared with prior art tool has the following advantages: 1) at casing both ends, stretch out outward annular flange, end cap is arranged on the end of casing and is bearing on the end face of annular flange, mounting screw coordinates end cap and casing is installed together with nut check through end cap and annular flange, this electric machine structure is simple, end cap end cap easy for installation, firm; 2) between end cap and annular flange, be provided with annular water proof ring, effectively improve the waterproof effect of motor, avoid motor entering water to damage; 3) casing is one drawing and forming, and production technology is simple, and cost is low, is convenient to batch production; 4) bearing outside is provided with insulating barrier with bearing chamber inwall, effectively reduces the potential safety hazard of bringing due to motor shaft electric current, and reliability is high; 5) end cap inwall is provided with temperature sensor, and motor internal is carried out to real-time temperature detection, controls motor out of service when motor internal excess Temperature, and reliability is high, avoids motor under hot conditions, to continue operation.
Accompanying drawing explanation
