The molded motor, in which the stator 1 of the motor is covered with resin except a tooth tip thereof and the portion covered with resin is cylindrical, is configured so that a protrusion 6 is integrally formed at a resin frame 3 of the stator 1 and the vicinities of both ends in the peripheral direction of a storage portion 13 of a sensor holder 11 are latched by the protrusion 6.
Description
Technical field
The present invention relates to the relatively large and big motor of vibration that use in the many places of moisture of washing machine geometric ratio.
Background technology
In the past, the known molding type motor (モ one Le De モ one タ) that use resin component covering stator winding is arranged.(with reference to patent documentation 1)
Under the situation of the such molding type motor that is used for air conditioner etc. of above-mentioned patent documentation, by the integrally moulded wiring substrate of resin, but at bigger motor, for example be used under the situation of washing machine etc., with the integrally moulded wiring substrate of motor the time, exist resin pressure when molded to cause wiring substrate or be configured in the problem of the electronic unit breakage on this wiring substrate.And wiring substrate is non-exchange.
In view of the above problems, known in the past have: the circular-arc wiring substrate that position transducer will be installed embeds the incorporating section, fixes by screw, the circular-arc sensor stand that utilizes casting resin to cover is set, and is installed on the end face of stator.(with reference to patent documentation 2)
In addition, near the known in the past motor that configuration overheat protector equitemperature protection component is arranged winding and utilize resin to cover.(with reference to patent documentation 3)

Use Fig. 1～7, embodiments of the invention are described.
According to Fig. 1, described stator 1 is covered by peucinous framework 2, and is integrally formed.It is shaped as annular, and all within it sides are taken in rotor (not shown).At the outer circumferential side of this stator 1,, on flange 3, be formed with the erection opening 4 that is used for mounting screw with the resinous framework 2 integrally formed flanges of installing to carriage (not shown) 3 that are useful on.
Following execution mode has illustrated the situation with the whole covering stators 1 of resin, but the part that is covered by resin also can only be covered by winding portion.
[embodiment 1]
(shape of sensor stand)
According to Fig. 2, sensor stand 11 comprises the incorporating section 13 of taking in wiring substrate 12 and is used to be installed in main part 14 on the stator 1, forms circular-arc corresponding to the shape of stator 1.This incorporating section 13 is configured in interior all sides of main part 14, and the circumferential lengths of incorporating section 13 forms the circumferential lengths of being longer than main part 14.
According to Fig. 3, the inner peripheral surface of the outer peripheral face of described incorporating section 13 and stator 1 joins, but is formed with a plurality of teats 16 on this outer peripheral face.
As the structure of patent documentation 1, the outer circumferential side of sensor stand 11 can form by screw on stator, but as shown in the present, from the main part 14 of sensor stand 11 fitting portion 17 is set downwards, and as described below, make the outer circumferential side of itself and stator 1 chimeric.When the thickness with this fitting portion 17 forms the 1mm～2mm left and right sides, can access elastic force to a certain degree, it is easier therefore to install.
(shape of stator of the present invention)
According to Fig. 4, the integral body that stator 1 covers except that the tooth front end by peucinous framework 2.Planar side at stator 1 is provided with installation portion 5, and this installation portion 5 is formed flatly so that sensor stand 11 is installed easily.All sides in the stator of this installation portion 5, two projections 6 are integrally formed with resinous framework 2, and the interval of these two projections 6 is provided with corresponding to the both sides (and width of cloth) of described sensor stand 11.Be formed flatly below this projection 6.
In addition, be formed with a plurality of tetragonal recesses 7 between described two projections 6, at the outer circumferential side of stator 1, two protuberances 8 are integrally formed with resinous framework 2.
(installation method of sensor stand of the present invention)
At first, make the incorporating section 13 of described sensor stand 11 downward-sloping, simultaneously, incorporating section 13 is accommodated in the below of described projection 6.Then, with the mode disposal subject portion 14 that the resinous framework 2 by stator 1 covers, make described fitting portion 17 chimeric with the protuberance 8 of stator peripheral part.Fig. 5 is installed in figure on the stator 1 with sensor stand 11.
Thus, the two ends of the incorporating section 13 of sensor stand 11 are by projection 6 fastenings top, and the teat 16 of the outer peripheral face side of incorporating section 13 is chimeric with recess 7, and interior all sides are fixed.On the other hand, at outer circumferential side, make described fitting portion 17 chimeric with the protuberance 8 of stator peripheral part.Thus, interior all sides, the outer circumferential side of sensor stand 11 are fixed reliably, become the structure that is difficult to come off with respect to vibration.
In addition, when taking off sensor stand 11, tilt to erect a little by making sensor stand 11, can take off sensor stand 11 from stator 1 easily, the loading and unloading when needing to change are easy.
[embodiment 2]
As shown in Figure 6, temperature protection component 21 is installed on sensor stand 11, this temperature protection component 21 is used to detect the temperature of stator 1 and protects stator 1 to avoid temperature anomaly.And, be formed with element incorporating section 22 in order to keep temperature protection component 21.
This element incorporating section 22 is formed with guide portion 23 to main part 14 openings of sensor stand 11 at this peristome.The thickness that forms about 1mm by the thickness with this guide portion 23 obtains elastic force, thereby obtains the confining force of temperature protection component 21.And the bottom opening of this guide portion 23 can detect the heat from stator reliably.And, on the sidewall of guide portion 23, be formed with a plurality of protuberances 24, push the upside of temperature protection component 21 with this.
In addition, near element incorporating section 22, be formed with a plurality of lead fastening portions 25 that are used for the lead of fastening temperature protection component 21.By forming a plurality of these lead fastening portions 25, can be corresponding to the length of multiple lead.
Moreover, on sensor stand 11, be used for being connected with wiring substrate 12 with the outside lead 26 that is connected.For the main part 14 by sensor stand 11 keeps this lead 26 to be provided with lead maintaining part 27.
Lead maintaining part 27 forms groove and keeps lead 26 on the main part 14 of sensor stand 11, by be integrally formed on the sensor stand 11 lead pressing device 28 and with respect to upward mobile pushing.
Moreover lead 26 uses is with 29 and kept by sensor stand 11.On sensor stand 11, be formed with to be used to allow and insert logical band inserting hole 30 with 29.
As shown in Figure 7, on stator 1, be formed with than the bigger hole 9,10 of described element incorporating section 22 or band inserting hole 30, and the main part 14 of chimeric ratio sensor support 11 cave in downwards each take in the position.
Utilizability on the industry
The motor of embodiment is used for the drive motor of washing machine, in particular for direct drive mode. Yet, also can be used in the motor that the off-premises station of for example air conditioner that requires water proofing property is used.
