Title:
COOLING AUXILIARY TOOL OF BRUSHLESS ROTARY ELECTRIC MACHINE INCLUDING STATOR WITH CYLINDRICAL COIL OF NON-IRON CORE AND BRUSHLESS ROTARY ELECTRIC MACHINE INCLUDING STATOR WITH CYLINDRICAL COIL OF NON-IRON CORE TO WHICH COOLING AUXILIARY TOOL IS MOUNTED
Document Type and Number:
Japanese Patent JP2018164373
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress increase of a temperature in the interior of a motor due to heat generation caused by an eddy current.SOLUTION: A cooling auxiliary tool 700 is structured that a plurality of adsorption holes 430 is formed in a bottom part so as to inlet an outer air into a space 540 formed by a rotator 3 having a bottom part 420, an interior side inner yoke 500, an outer yoke 600, and a plurality of magnets 4, and a stator 2 to which a non-iron core cylindrical coil 200 is fixed; and an annulus ring that a plurality of exhaust holes 660 communicated to an air gap 40 formed by the inner yoke and the outer yoke that are communicated with the space is fitted and fixed in an outer periphery which is closed to the bottom part of the outer yoke in a coreless and brushless motor projected in a band state in the outer periphery that is closed to the bottom part of the outer yoke. The cooling auxiliary tool has a plurality of radial communication ports 720 provided so as to match to the exhaust hole projected in the outer yoke.SELECTED DRAWING: Figure 1
