Abstract
An electric work machine (1) includes: a motor (6) having a rotor (23), which rotates about a rotational axis relative to a stator (22A; 22B; 22C; 22D); an output part (8) driven by the rotor; and a temperature-detecting device (101; 111; 121; 131) disposed on or in the stator. The stator includes: a stator core (33; 330) having teeth (38; 380), which radially protrude from a yoke (37); an insulator (34; 340), which has tooth-covering parts (42; 420) that respectively cover at least a portion of surfaces of the respective teeth and is fixed to the stator core; and coils (35; 350) respectively wound on the teeth over the tooth-covering parts. The temperature-detecting device is disposed in a recess (56) provided on (in) the insulator.
