It has been known that there is internal rotor type and outer rotor-types.Internal rotor type is configured to be wound with the stator arrangement of coil in outside, incites somebody to action
The rotor for being provided with permanent magnet is accommodated in the inside of stator.On the other hand, outer rotor-type is opposite to that, is configured to be provided with
The stator for being wound with coil is accommodated in the inside of rotor in outside by the rotor configuration of permanent magnet.
In the in-wheel motor of interior rotor type, discharged by the heat that coil generates via motor case, but in outer rotor
In the in-wheel motor of type, due to being wound with inside of the stator arrangement in rotor of coil, so being easy by the heat that coil generates
It accumulates in inside.In particular, needing height in the in-wheel motor of the outer rotor-type for the direct drive mode for not needing speed reducer
Torque, therefore the calorific value of coil is more, it is desirable that the technology for discharging the heat for lodging in stator well.
In patent document 1, the technology for improving the heat dissipation of in-wheel motor of outer rotor-type is proposed.1 institute of patent document
The in-wheel motor of proposition by rotor and stator and between space part in fill cooling oil and make heat distribution inside motor
Uniformly.In addition, being provided with the holding vessel of storage cooling oil, holding vessel and space part in the outside of in-wheel motor and being connected using pipeline
Knot.The holding vessel is opened wide to atmosphere, even if due to temperature change volume change occurs for the cooling oil in in-wheel motor, also can
Receive or supply the cooling oil of the volume change.
In addition, being the in-wheel motor of outer rotor-type in patent document 2, wherein the shell in the periphery of covering rotor core
The outer surface opposed with wheel on erect the fin radially extended, formed between the inner peripheral surface of wheel and the outer peripheral surface of shell
There is the flow path that the vehicle side space of in-wheel motor is connected with outer space.Shell is set to play a role as radiator as a result, together
When, by the effect of centrifugal fan, the air for generating the outside of wheel passes through the air stream of wheel via the outer peripheral surface of shell, by this
Air stream, to new outside air is constantly imported between fin, to improve heat dissipation effect brought by fin.
