Description
Technical field
The utility model relates to technical field of motors, especially a kind of long spindle motor.
Background technique
The first choice that spindle motor is small-power vertical sewage pump is lengthened, during long-term production, since extension shaft does not have
National standard, so motor special life the case where can only be according to each producer, when the motor due to extension shaft is due to the length of casing
Degree length, therefore heat is difficult to distribute, and due to long axis itself weight it is big, the performance of motor itself is by shadow
It rings.
Utility model content
It is good to provide a kind of light-weight axis, easy heat radiation, performance for the shortcomings that the purpose of the utility model is to overcome the prior arts
Long spindle motor.
The purpose of this utility model is achieved through the following technical solutions: a kind of long spindle motor, including long cylinder casing, length
Axis, long axis passes through long cylinder casing along axis and the two is installed in end point by bearing, is arranged with rotor, long cylinder casing on long axis
Inner wall on be provided with stator, the both ends of long axis are stretched out outside long cylinder casing, and the both ends of long cylinder casing do not pass through end cap seal；
The long axis is hollow shaft, is provided with multiple heat-sink units, the heat dissipation on the wall of hollow position in long axis
Include multiple parallel cooling fins in unit, cooling fin perpendicular to long axis axis, and the sagittal plane of cooling fin and long axis it
Between there is angle, the length of multiple parallel cooling fins successively reduces, and cooling fin is mounted on the hollow position of long axis by mounting blocks
Set place；
Position of bearings is provided with fan blade on long axis in the long cylinder casing.
It is arranged cored in the rotor, iron core is around with armature winding.
The right end of the long axis draws the electrical lead of armature winding, and the right end of long axis is provided with the connector of spline-like.
Be provided with the different slot of multiple length along its axial direction on the wall of the hollow part of the long axis, mounting blocks by the slot into
Row is installed and is fixed by glue.
The both ends of the long cylinder casing are provided with fixed cylinder, fix bearing by fixed cylinder and lock.
The utility model, which has the advantage that, sets hollow for long axis, significantly reduces the weight of long axis, convenient for length
The rotation of axis improves the performance of motor；The setting of heat-sink unit and radiator fan then ensure that the excellent heat dissipation of motor in long axis
Effect；But the setting that the height of cooling fin successively reduces in hot cell then allows abutting fins will not to the air-flow generated each other
Obstruction is generated, convenient for heat dissipation；The slot of rapid heat dissipation and long axis in heat-sink unit, then allow radiating block that can quickly install；Long cylinder
The setting of casing end-cover-free then further provides heat dissipation effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of punching；
Fig. 2 is the structural schematic diagram of heat-sink unit；
In figure: 1- long cylinder casing, 2- long axis, 3- rotor, 4- stator, 5- heat-sink unit, 6- cooling fin, 7- mounting blocks, 8-
Fan blade.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in Fig. 1 and figure, a kind of long spindle motor, including long cylinder casing 1, long axis 2, long axis 2 pass through long cylinder machine along axis
Shell 1 and the two are installed in end point by bearing, are arranged with rotor 3 on long axis 2, are provided with stator on the inner wall of long cylinder casing 1
4, the both ends of long axis 2 are stretched out outside long cylinder casing 1.
Further, the long axis 2 is hollow shaft, is provided with multiple heat-sink units on the wall of hollow position in long axis 2
5, it include multiple parallel cooling fins 6 in the heat-sink unit 5, axis of the cooling fin 6 perpendicular to long axis 2, and cooling fin 6
There is angle between the sagittal plane of long axis 2, the length of multiple parallel cooling fins 6 successively reduces, and cooling fin 6 passes through mounting blocks
7 are mounted at the hollow position of long axis 2.
