Abstract
An electric work machine includes a smaller motor. An electric work machine includes a motor and a housing accommodating the motor. The motor includes a stator and a rotor rotatable about a rotation axis. The stator includes a stator core, an insulator fixed to the stator core, a plurality of coils fixed to the insulator, and a terminal connected to each of the plurality of coils. The housing includes at least one first tab in contact with at least a part of a surface of the stator. The at least one first tab is at the same position as at least a part of the terminal in an axial direction parallel to the rotation axis.
Claims19
An electric work machine, comprising:
- a motor including
- a stator including
- a stator core,
- an insulator fixed to the stator core,
- a plurality of coils fixed to the insulator, and
- a terminal connected to at least one of the plurality of coils, and
