Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/048222
Kind Code:
A1
Abstract:
In the present invention, a motor device (60) has a stator (200), a rotor (300), a shaft (340), a power busbar (261), and a resolver (421). The shaft (340) has a shaft body (341) that rotates with the rotor (300). The power busbar (261) is provided in a position that is spaced radially outward from the shaft body (341). The power busbar (261) extends annularly in a circumferential direction (CD). The resolver (421) is provided to the shaft body (341) and detects the rotation angle of the shaft body (341). The resolver (421) is provided in a position that is spaced radially inward from the power busbar (261). The resolver (421) is in a state of being inserted between the power busbar (261) and the shaft body (341).
