Through hole 3c is connected through the sensor and is screwed in the screw hole so as to which velocity sensor 6 is fixed on into controller housing 5a
It is interior, and the induction end 6a of velocity sensor 6 is stretched out outside controller housing 5a through the sensor resigning hole 5d.
The built-in motor of the present embodiment also includes being enclosed on the axis and producing week when it is by circumferential twisting resistance
Axle sleeve 7 to deformation and the chain wheel (being not drawn into figure) being set on the axle sleeve, it is provided with and can feels on the axle sleeve 7
Should circumferential twisting resistance size suffered by axle sleeve moment sensing component 8, the moment sensing component through an outgoing line device with it is described
Electric machine controller 5 is connected.The outgoing line device is by dynamic magnetic core 12a, the moving winding 12b being fixed on the dynamic magnetic core, magnetostatic core
The 7a and dead line circle 7b that is fixed on the magnetostatic core is formed, the dynamic magnetic core 12a, moving winding 12b, magnetostatic core 7a and quiet
Coil 7b is cirque structure, wherein dynamic magnetic core 12a fixes with axle sleeve 7, magnetostatic core 7a is relatively fixed with bicycle five-pipe,
The dynamic magnetic core 12a is contacted and can relatively rotated with magnetostatic core 7a fittings, and the moving winding 12b passes through moving winding lead-out wire
12c is connected with the moment sensing component, and the dead line circle 7b passes through quiet lead-out wires of coil 7c and the phase of electric machine controller 5
Even.
The specific assembly method of above-mentioned velocity response magnet steel 9 is：An annular magnetic steel seat is fixed with the dynamic magnetic core 12a
10, the velocity response magnet steel 9 is fixed on the annular magnetic steel seat 10.Because annular magnetic steel seat 10 and dynamic magnetic core 12a are fixed, and
Dynamic magnetic core 12a is fixed with axle sleeve 7, and axle sleeve 7 is fixed on axis 4, then velocity response magnet steel 9 is naturally also just relative with axis 4
It is fixed.When axis 4 rotates, the concomitant rotation of velocity response magnet steel 9 will be driven.
The dynamic magnetic core 12a, moving winding 12b, magnetostatic core 7a, dead line circle 7b and annular magnetic steel seat 10 are housed in the machine
In seat accommodating cavity 2a, to reduce dynamic magnetic core 12a, moving winding 12b, magnetostatic core 7a, dead line circle 7b and annular magnetic steel seat 10 and the external world
The possibility of grazing occurs for object.
In this example, the specific fixed form between the magnetostatic core 7a and support 2 is as follows：The support accommodating cavity 2a of support 2
In to be formed with three positioning holes 2b, magnetostatic core 7a being distributed in a ring circumferentially fixed in these three positioning holes by three locating pieces 11
In 2b.And in order to ensure the compactness between magnetostatic core 7a and support 2, this example is folded between magnetostatic core 7a and support 2 is in
Three springs of annular spread, the spring are applied with the axial elastic force towards dynamic magnetic core direction to magnetostatic core.
The axial cross section of the dynamic magnetic core and magnetostatic core is U-shaped (having an opening surface), and the two is bonded to each other and structure
The loop configuration for having hollow axial cross section into one, moving winding and the dead line circle are housed in by dynamic magnetic core and magnetostatic core
In the loop configuration with hollow axial cross section formed.
A closing structure is formed because the opening surface of magnetostatic core and dynamic magnetic core fits together, therefore dead line circle and moving-wire
Circle be at one closure magnetic circuit in, thus it is equivalent into a transformer, dead line circle be the equal of transformer primary side,
And moving winding is the equal of then transformer secondary.In practical application, the primary side that need to first pass through electric machine controller to transformer is (quiet
Coil) add a certain size alternating current, then and transformer secondary (moving winding) will induce a certain proportion of alternating current, sense
This alternating current that should go out is loaded on moment sensing component, moment sensing component be this transformer load, load
It is to change with the size of torsion suffered by axis, therefore electric machine controller can be read by the primary side (dead line circle) of transformer
To the size of this load, torque size that moment sensing component sensed is known with this.By this principle, we can
To be easy to the torque signals that moment sensing component is sensed being transferred to electric machine controller, then by electric machine controller according to this
The size of one torque signals adjusts the power output of motor.
Certainly, the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to make people much of that
Solution present disclosure is simultaneously implemented according to this, and it is not intended to limit the scope of the present invention.It is all according to major technique of the present invention
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all be included within the scope of the present invention.
