WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/276354
Kind Code:
A1
Abstract:
Provided is a work machine wherein ease of assembly has been improved by an innovation in the structure (motor coil connection structure) of a motor. Stator coils are configured to be delta-connection parallel windings. A crossover 48 that connects a V-phase stator coil V2 and a U-phase stator coil U2 and a crossover 48 that connects a U-phase stator coil U1 and a V-phase stator coil V1 cross, by way of two projecting parts 54, between circumferential-direction neighboring winding slots of the V-phase stator coil V2 and the U-phase stator coil U1. A fusing terminal 57 is incorporated with respect to the set of two projecting parts 54 where the fellow crossovers 48 cross.
