Title
(EN) ELECTRIC WORK MACHINE
(FR) MACHINE DE TRAVAIL ÉLECTRIQUE
(JA) 電動作業機
Abstract
(EN)
An electric work machine according to one aspect of the present disclosure comprises a motor, a drive unit, and a rotation sensor. The motor comprises a stator and a permanent-magnet-type rotor. The stator comprises a cylindrical body, a plurality of teeth, and a plurality of coils. The rotation sensor is provided in a region closer to the rotor than a region where the plurality of coils are present in the radial direction of the stator.
(FR)
Selon un aspect de la présente invention, une machine de travail électrique comprend un moteur, une unité d'entraînement et un capteur de rotation. Le moteur comprend un stator et un rotor de type à aimant permanent. Le stator comprend un corps cylindrique, une pluralité de dents, et une pluralité de bobines. Le capteur de rotation est disposé dans une région plus proche du rotor qu'une région contenant la pluralité de bobines dans la direction radiale du stator.
(JA)
