Problems solved by technology

[0002] Most of the thermostats of existing motors adopt the method of embedding the winding coils and binding them on the stator winding coils. The operation is more complicated. At the same time, when the windings are embedded and wrapped with tape and bound, it is easy to cause the thermostat shell to be crushed and the windings to be damaged. , Tape loosening and other risks, resulting in adverse hidden dangers such as abnormal operation of the thermostat
Recently, some motor manufacturers also fix the thermostat by setting accommodating parts for the thermostat on third-party components (such as electric control boards), but the structure is more complicated and the cost is higher

Embodiment 1

[0036] Please also refer to Figure 1 to Figure 3 Now, the fixing structure of the motor thermostat 1 provided by a preferred embodiment of the present invention will be described. The fixed structure of this kind of motor thermostat 1 includes a thermostat 1 and an insulating frame 3 arranged on the stator core 2 of the motor; it also includes a flexible fixing member 5; the insulating frame 3 is provided with at least one flexible fixing member 5 around the threading part; the flexible fixing part 5 passes through the threading part and surrounds the thermostat 1, the stator core 2 and the stator winding 4 wound on the insulating frame 3 to fix and attach the thermostat 1 to the Stator winding 4, so that the thermostat 1 is fixed and pasted on the stator winding 4, so that the thermostat 1 is close to the stator winding 4, and the temperature monitoring of the stator winding 4 is very accurate. In this embodiment, the insulating frame 3 includes a fixing sleeve 30 , and the...

Embodiment 2

[0042] Please also refer to Figure 4 to Figure 6 The difference between this embodiment and Embodiment 1 is that at least one groove is provided outside the yoke portion 21 of the stator core 2, the flexible fixing member 5 surrounds the outside of the yoke portion 21 of the stator core 2, and the flexible fixing member 5 Wrapping in the groove, compared to the way in which the flexible fixing member 5 passes through the gap between the insulating frame 3 and the inner surface of the yoke 21 of the stator core 2 in the first embodiment, the flexible fixing member 5 is directly inserted from the outside It is easier to wrap around, which can greatly improve the operating efficiency; and because the flexible fixing part 5 is completely accommodated in the groove, it does not exceed the outer surface of the yoke 21 of the stator core 2, so it will not interfere with the motor after assembly. contact with or interfere with other components.

Embodiment 3

[0045] Please also refer to Figure 7 to Figure 9 The difference between this embodiment and Embodiment 1 is that the threading part is the through hole 3120, 3220 provided on the fixed sleeve 30 instead of the notch 3121, 3221, although the through hole will reduce the impact on the thermostat 1 relative to the notch. The efficiency of fixed assembly, but its limit effect is better;

[0046] Also see Figure 13 , the insulating frame 3 includes a first insulating frame body 31 and a second insulating frame body 32 butted against each other, and the fixing sleeve 30 includes a first sleeve 312 on the first insulating frame body 31 and a first sleeve 312 on the second insulating frame body 32. The second sleeve 322 can only set the through hole 3120 on the first sleeve 312 or only set the through hole 3220 on the second sleeve 322. Of course, when it is set alone, the thermostat 1 can only be fixed when the through hole One side of the first insulating frame body 31 of the ho...

Abstract

The invention provides a fixed structure of a motor temperature controller and a motor applied thereto. The fixed structure temperature controller and an insulating frame arranged on the stator core of the motor; also includes a flexible fixing piece; the insulating frame is provided with At least one threading part for the flexible fixing part to go around; the flexible fixing part passes through the threading part and surrounds the thermostat, the stator core and the stator winding wound on the insulating frame to fix the thermostat and attach it to the On the stator winding; and this kind of motor adopts the fixed structure of the aforementioned motor thermostat. The fixing structure of the motor temperature controller and the motor provided by the present invention have simple and compact structure, low cost, easy assembly, easy automatic operation and can effectively ensure that the flexible fixing part will not touch the winding coil, avoiding the traditional process that requires The thermostat is embedded in the winding, which is prone to risks such as thermostat and winding damage, loose tape, etc., which can effectively ensure the stability of the thermostat.

technical field [0001] The invention belongs to the technical field of motors, and more specifically relates to a fixing structure of a temperature controller of a motor and a motor using the fixing structure of the temperature controller. Background technique [0002] Most of the thermostats of existing motors adopt the method of embedding the winding coils and binding them on the stator winding coils. The operation is more complicated. At the same time, when the windings are embedded and wrapped with tape and bound, it is easy to cause the thermostat shell to be crushed and the windings to be damaged. , Tape loosening and other risks, resulting in adverse hidden dangers such as abnormal operation of the thermostat. Recently, some motor manufacturers fix the thermostat by installing a housing part for the thermostat on a third-party component (such as an electric control board), but the structure is more complicated and the cost is higher.
