Title:
ELECTRIC WORK MACHINE AND PRODUCTION METHOD FOR ELECTRIC WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/250999
Kind Code:
A1
Abstract:
The present invention curbs the production costs of an electric work machine. This electric work machine 1 comprises: a first brushless motor 6001 comprising a first stator 201 that comprises a first stator core 211 and a plurality of first coils 241 that are wound around each of a plurality of teeth 21T of the first stator core 211, and a first rotor 3001 that is combined with the first stator 201; and a controller 9 that magnetically excites the teeth 21T such that the first rotor 3001 rotates about a rotation axis. In a plane orthogonally intersecting with the rotation axis, the shape of the first stator core 211 is equivalent to the shape of a second stator core 212 of a second stator 202 used in a second brushless motor 6002 of another electric work machine 101. The first rotor 3001 is capable of being combined with the second stator 202. The number of poles of the first rotor 3001 differs from the number of poles of a second rotor 3002 used in the second brushless motor 6002.
