That is, there are following such aspects that should improve for the previous gimmick comprising above-mentioned such technology.That is,
In the case where temperature sensitive member breaks down, can not detection winding temperature.Even if motor becomes abnormal shape as a result,
State is also used for the control of driving fan motor by the signal that temperature sensitive member notice winding temperature has reached predetermined temperature without normal direction
Portion's transmitting processed.Thus, the constant temperature of winding rises.As a result, previous motor can not safely shut down.Also can think
It arrives, in the worst case, previous motor can catch fire.
Therefore, in embodiments of the present invention, even if the case where the protective device for being installed on motor does not function
Under, motor will not cause to catch fire, and seek the raising of the safety of motor.
Hereinafter, being described with reference to embodiments of the present invention.In addition, the following embodiments and the accompanying drawings is to embody the present invention
An example, not limit the scope of the invention.
(embodiment)
Fig. 1 is the half sectional view obtained from the motor of embodiments of the present invention from side.Illustrate this reality using Fig. 1
Apply the motor of mode.It is illustrated in addition, the following description illustrates fan motor used in air conditioner.
As shown in Figure 1, the motor 100 of present embodiment includes stator 10, rotor 20, bearing 30, molding section 40 and branch
Frame 50.
Stator 10 has the stator core 11 extended along the axle center direction 21a, is wound in the winding 12 of stator core 11 and is located at
Insulation division 13 between stator core 11 and winding 12.
Rotor 20 is located at the position facing across gap with stator 10.Rotor 20 has using axle center 21a as rotation center
Rotary shaft 21 and extend and be installed on the rotary body 22 of rotary shaft 21 along the axle center direction 21a.
A pair of bearings 30 (30a, 30b) rotates freely the bearing of rotary shaft 21.
Molding section 40 covers that side facing with rotor 20 of stator 10 at stator 10 using resin moulded parts 41
Opposite side.
Bracket 50 is located at end of the motor 100 on the direction 21a of axle center, also, is installed in a manner of keeping bearing 30a
Molding section 40.
Insulation division 13 is the component with insulating properties, is formed by the resin that flash-point is 330 DEG C or more.It is further preferred that shape
It is preferable for 350 DEG C or more of resin using flash-point at the resin of insulation division 13.
In addition, it is as described below to play the role of especially significant, effect mode.
That is, the resin shape that insulation division 13 used in the motor 100 of present embodiment is 420 DEG C or more by ignition temperature
At.It is further preferred that the resin for forming insulation division 13 is preferred using the resin that ignition temperature is 480 DEG C or more.
In addition, the resin shape that insulation division 13 used in the motor 100 of present embodiment is 250 DEG C or more by melting temperature
At.It is further preferred that the resin for forming insulation division 13 is preferred using the resin that melting temperature is 280 DEG C or more.
