  • Motor and electric tool equipped with the same
    Patent number: 10530224
    Abstract: A motor includes: a stator; a rotor axially aligned with the stator; a circuit board; and a heat dissipating plate. The stator includes: an iron core including teeth; an insulator covering one end surface, in the axial direction, of the iron core; and a coil wound around the teeth. The insulator includes an electrically insulating material having a lower rate of heat transfer than a material included in the iron core. The heat dissipating plate is attached to the insulator in a state in which the heat dissipating plate is in contact with the insulator without being in contact with the iron core, and the circuit board is attached to the heat dissipating plate in a state in which the circuit board is in contact with the heat dissipating plate without being in contact with the iron core.

  • TIP TOOL HOLDER AND POWER TOOL
    Publication number: 20170259422
    Abstract: A tip tool holder includes a nail portion to be inserted in an attachment hole formed in a power tool, an accommodation portion capable of accommodating a tip tool, and an opening opposite to the nail portion. The accommodation portion accommodates the tip tool such that an axis of the tip tool is substantially perpendicular to a direction in which the nail portion and the opening face each other. The tip tool holder includes a first arm and a second arm opposite to each other. The opening is included in the first arm while the nail portion is provided to the second arm.
