Document Type and Number:
WIPO Patent Application WO/2023/048224
Kind Code:
A1
Abstract:
A motor device (60) has a motor housing (70), a stator (200), and a rotor (300). An axial gap (475) is formed between the stator (200) and the rotor (300). An internal space of the motor housing (70) includes a stator region (471), an opposite region (472), and an outer circumferential region (473). In the axial gap (475), a gap outer circumferential end (476) communicates with the opposite region (472) through the outer circumferential region (473). The rotor (300) is provided with a holder adjustment hole (326), a holder central hole (324), and the like. In the axial gap (475), a gap inner circumferential end (477) communicates with the opposite region (472) through the holder adjustment hole (326), the holder central hole (324), and the like.
