Abstract
An electric work machine (1) includes: an inner-rotor-type brushless motor (6) having a stator (20) disposed around a rotor (30); and an output part (10), which is directly or indirectly driven by the rotor. The rotor comprises a rotor core (32) and eight permanent magnets (33) fixed to the rotor core. The stator comprises a stator core (21), one or more insulators (22, 23) fixed to the stator core, and six coils (24), which are respectively wound on teeth (21T) of the stator core via the insulator(s).
