ELECTRIC WORK MACHINE AND METHOD OF MANUFACTURING THE SAME

原文（中国語）

In one aspect of the present disclosure, an electric work machine () includes a brushless motor () having a rotor () and a stator (). The rotor comprises a plurality of permanent magnets () disposed such that like poles oppose each other in a circumferential direction of a rotor core () and thereby form a plurality of magnetic poles at an outer circumference of the rotor core in the circumferential direction thereof. The number of magnetic poles is 4m (where m is a natural number), and the stator has 3m slots. The rotor rotates at an electric frequency of 1,333 Hz or more.
