To position the electrical property pin 14, can be aligned with the weld part 131 after so that the electrical property pin 14 is passed through the guide hole 121.The partition
The part of the adjacent second side 12b of 12 inner peripheral surface 122 can abut the electrical property pin 14, to promote the partition 12 to the electrical property
Locating effect provided by pin 14.
Also, the aperture of the guide hole 121 by the first side 12a of the partition 12 towards second side 12b decrescence, therefore the partition 12
Inner peripheral surface 122 the electrical property pin 14 will not be hindered to protrude into the guide hole 121, and the inner peripheral surface adjacent to the part of first side 12a
122 can guide the electrical property pin 14 across the guide hole 121, make the electrical property pin 14 can in the assembling process of the stator 1
Easily pass through the guide hole 121.
In more detail, the inner peripheral surface 122 of the partition 12 includes a guidance part 122a, and guidance part 122a is by the partition 12
The first side 12a form tapered cone cell towards second side 12b.Whereby, guidance part 122a can make the aperture of the guide hole 121 by this
Decrescence towards second side 12b, and guidance part 122a can guide the electrical property pin 14 across the guide hole to first side 12a of partition 12
121。
In the present embodiment, which separately includes an opening portion 122b, and opening portion 122b is set to the guiding
Between portion 122a and the first side 12a of the partition 12, and opening portion 122b forms cylindrical shape, so as to controlling the guide hole 121
Aperture, the aperture to avoid guide hole 121 towards the side of the iron core 11 are excessive.Alternatively, shown in referring to figure 4., in the present invention
In the motor of another embodiment, which separately includes a limiting section 122c, and limiting section 122c is set to the guidance part
Between 122a and second side 12b of the partition 12, limiting section 122c forms cylindrical shape.By the cylindric limiting section of setting
122c can further promote the partition 12 to locating effect provided by the electrical property pin 14.Also, limiting section 122c can
To abut the electrical property pin 14, limiting section 122c is enable to effectively increase the contact of the inner peripheral surface 122 and the electrical property pin 14
Area
Referring again to shown in Fig. 1 to Fig. 4, which is equipped with a protrusion 123, the protrusion in the position of the guide hole 121

The upward depth of histogram is worn with ensuring that the partition 12 can position the position of the electrical property pin 14 and guide the electrical property pin 14
Cross the guide hole 121.In addition, as shown in figure 3, the protrusion 123 can keep spacing with the circuit board 13；Alternatively, as shown in figure 4,
The protrusion 123 can abut the circuit board 13 towards the surface of the partition 12, and whereby, which can also the auxiliary positioning electricity
Road plate 13, to promote the overall structural strength of the stator 1.
It please refers to shown in Fig. 1 and Fig. 2, in section Example of the present invention, which includes a sensor 4, the sensing
Device 4 can need the sensing device of the adjacent iron core 11 setting for position sensor, temperature sensor or overheat protector switch etc., because
The first side 12a in the partition 12 can be set in this sensor 4, and the sensor 4 and the circuit board 13 is made to be respectively formed in this
The two sides of partition 12.The partition 12 is additionally provided with a through-hole 124, which is equipped with a wears groove 132, which passes through
The both side surface of the circuit board 13 is worn, and the wears groove 132 is connected with the through-hole 124.The circuit board 13 can be backwards to should be every
The surface of plate 12 is equipped with an electric pedestal 133.Whereby, which connects a conducting wire 41, which can be logical across this
Hole 124 and the wears groove 132, and the circuit board 13 is extended to backwards to the surface of the partition 12 to connect the electricity pedestal 133.
Relatively, in the stator of aforementioned existing motor, although the partition is equipped with a perforation, adjacent iron core setting
The conducting wire that is connected of sensor pass through the perforation after, be only capable of being connected with the circuit board towards the component on the surface of the partition
It connects.Wherein, which is located between the circuit board and the partition towards the surface of the partition, therefore the conducting wire is connected to
The operation of the circuit board is difficult to carry out；Also, since the space between the circuit board and the partition is quite narrow, if the conducting wire
Length it is longer, may cause the conducting wire and shore the circuit board, and have a negative impact to the assembling stability of the stator.
Wears groove 132 is arranged by the circuit board 13 in the stator 1 of the motor of section Example of the present invention, can be for the sensing
The conducting wire 41 connected on device 4 is connected with electric pedestal 133 of the circuit board 13 on the surface of the partition 12, so that should
The operation that conducting wire 41 is connected to the circuit board 13 is easy to carry out, to promote the assembling convenience of the stator 1.Further, since the electricity
First side 12a of road plate 13 has biggish space for accommodating the conducting wire 41, will not even if the length of the conducting wire 41 is longer
Influence the assembling stability of the stator 1.Wherein, which can penetrate through the outer peripheral edge of the circuit board 13, make the conducting wire 41 can
To be more easily through the wears groove 132, the assembling convenience of the stator 1 is further promoted.
In addition to this, please refer to shown in Fig. 1 and Fig. 2, in section Example of the present invention, the motor be additionally provided with one every
From cover 3, which includes first cover 31 and second cover 32, the partition 12 of the stator 1 be set to this first
Between cover 31 and second cover 32, which is set between first cover 31 and the partition 12, the circuit board 13
It is set between second cover 32 and the partition 12, and the shaft 21 of the rotor 2 can pass through first cover 31 to stretch out
To the isolation cover 3.Whereby, which can effectively block external aqueous vapor or foreign matter and enter inside the isolation cover 3, from
And good moisture-proof or dust-proof effect can be provided to other components inside the stator 1 and the isolation cover 3.
In conclusion guide hole 121 is arranged by the partition 12 in the motor and its stator 1 of various embodiments of the present invention, and make
The aperture of the guide hole 121 by the first side 12a of the partition 12 towards second side 12b decrescence, i.e., using the partition 12 position the electricity
Property pin 14 position, to ensure that the electrical property pin 14 is easy to be electrically connected with the circuit board 13.In addition, the partition 12
Inner peripheral surface 122 can guide the electrical property pin 14 across the guide hole 121, make the electrical property pin 14 in the assembling process of the stator 1
In can easily pass through the guide hole 121.Accordingly, the piercing aperture for comparing the partition of the stator of aforementioned existing motor is larger
When, which can not provide any locating effect to electrical pin, and when the aperture of the perforation is smaller, it will lead to electrical pin
Be difficult to across the perforation, the motor stator of various embodiments of the present invention can be positioned by the partition 12 position of the electrical property pin 14 with
And the electrical property pin 14 is guided across the guide hole 121, have effects that promote the assembling convenience of the stator 1 really.
