  • Publication number: 20210296955
    Abstract: An electric work machine (1; 301), such as a power tool, includes a motor (8; 8B) having a rotor (19), which is rotatable relative to a stator (20; 20B). The stator includes: a stator core (32; 120) having teeth (37; 130); an insulator (33, 34; 122) supported by the stator core; coils (35, 112) wound through the insulator and around the teeth; a first wire (101; 149) that connects a first set of the coils; and a second wire (102; 149) that connects a second set of the coils. At least a portion of the first wire and at least a portion of the second wire are disposed in a same range in a circumferential direction of the stator. In at least a portion of that range, the first wire and the second wire are non-contactable and/or incapable of relative movement, whereby premature wire deterioration can be reduced.
