Title:
ELECTRICALLY-DRIVEN WORK MACHINE
Document Type and Number:
Japanese Patent JP2023060669
Kind Code:
A
Abstract:
To provide an electrically-driven work machine having a temperature detection unit that detects the temperature of a stator.SOLUTION: An electrically-driven work machine includes: a motor having a stator 22A and a rotor that rotates around a rotation shaft with respect to the stator; an output section driven by the rotor; and a temperature detection unit 100A disposed on the stator. The stator has: a stator core 33 including a yoke and teeth protruding in a radial direction from the yoke; an insulator 34 having a teeth-covering portion that covers at least part of the surface of the teeth and fixed to the stator core; and a coil wound around the teeth via the teeth covering portion. The temperature detection unit is disposed in a recess 56 provided on the insulator. The motor is air cooled by a fan.SELECTED DRAWING: Figure 9
