The purpose of the present invention is completed by following technical solution, this to include from cooling totally enclosed type asynchronous machine
Base, stator, rotor and motor shaft, described stator are fixed on the side of base, the rotor be fixed on motor shaft and with
Stator is in corresponding distribution；The periphery in space is covered with the first housing where described stator, rotor, and the bottom of first housing leads to
Cross and be bolted on base side；Binding post is fixed with the first shell outside, the space where the binding post
Periphery is covered with the second housing, and the bottom of second housing is bolted on the side of the first housing；With described stator
The fan blade for making to accelerate air flow in machine cavity is provided with the rotor of the corresponding distribution side, its fan blade is toward calmly
The lateral ends of son.
Preferably, the first described housing, the second housing are the revolving body for being built-in with cavity, and first housing,
The base that the bottom of two housings is provided with is the side along convex edge on the outside of housing body.
Preferably, the depth for the cavity put in described first shell body is more than axial direction side where described stator, rotor
Upward whole height.
Preferably, the depth for the cavity put in described second shell body is more than the height of described binding post.
Preferably, the first described housing end face center opening position is provided with a boss to stretch out.
Preferably, the center of described boss and the shaft core of motor shaft are located along the same line.

Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing 1：The present invention includes base 1, stator 2, rotor 3 and motor
Axle 4, described stator 2 are fixed on the side of base 1, and the rotor 3 is fixed on the motor shaft (4) and with stator 2 in corresponding point
Cloth；Described stator 2, the periphery in the place space of rotor 3 are covered with the first housing 5, and the bottom of first housing 5 is bolted
On the side of base 1；Binding post 6 is fixed with the lateral surface of the first housing 5, is covered in the periphery in the place space of binding post 6
There is the second housing 7, the bottom of second housing 7 is bolted on the side of the first housing 5；It is in described stator 2
The rotor 3 of the corresponding distribution side is provided with the fan blade 8 for making to accelerate air flow in machine cavity, its fan blade 8 toward
The lateral ends of stator 2；Pass through said structure so that asynchronous machine of the invention has totally-enclosed, self cooled advantage, is wind
The preferable corollary equipment of machine, pump machines.
Described the first housing 5, the second housing 7 are the revolving body for being built-in with cavity, and first housing 5, the second housing 7
The base 9 that is provided with of bottom be side along convex edge on the outside of housing body；The wherein outermost on the base 9 of the first housing 5 and bottom
The outermost of seat 1 is concordant so that the aesthetics of motor improves.
The depth of cavity built in the first described housing 5 be more than described stator 2, rotor 3 in the axial direction
Whole height；Size apart is 6 to 10 millimeters between the two, and its optimum distance is 8 millimeters；The axial direction of motor was so both ensured
Size, the normal operation of motor is not interfered with again so that the axial dimension of motor greatly shortens.
The depth of cavity built in the second described housing 7 is more than the height of described binding post 6；Between the two apart
Size is 4 to 7 millimeters.
The lateral ends of son
The side of the boss 51 is skewed, and the internal diameter size of boss is more than the diameter dimension of motor shaft.
The center of described boss 51 and the shaft core of motor shaft 4 are located along the same line, so just in case motor shaft 4 is altered
When dynamic, because leaving certain gap between the end face of boss 51 and motor shaft so that motor shaft can be buffered, so as to reduce
The damage of motor and the generation of accident.
Sealing ring is installed on the stationary plane between the bottom of the first described housing 5 and base 1, increases sealing effectiveness.
