Title:
STATOR, AND PROPELLER DRIVING APPARATUS AND AIRCRAFT USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/231211
Kind Code:
A1
Abstract:
The present invention relates to a stator having an excellent heat dissipation effect since an insulator (or bobbin) which insulates between a stator core and a coil is formed by using an insulating and heat-dissipating composite material having both heat dissipation performance and insulating performance, and a propeller driving apparatus and aircraft using the stator. The propeller driving apparatus comprises: a radial gap-type BLDC motor having an inner rotor-outer stator structure, in which a rotor is arranged inside a stator in a circumferential shape with an airgap interposed therebetween; and a propeller installation bracket for installing the propeller on the rotary shaft of the motor, wherein the stator comprises: a stator core having an annular back yoke having a certain width so as to form a magnetic circuit and a plurality of teeth extending from the back yoke in the direction toward the center; an insulator formed to surround the outer circumferential surface, on which a coil is to be wound, in each of the plurality of teeth; and a stator coil wound on the outer circumferential surface of the insulator in each of the plurality of teeth. The insulator is formed of the insulating and heat-dissipating composite material having both heat dissipating performance and insulating performance.
