  • Motor, motor assembly, and air conditioner
    Patent number: 11605992
    Abstract: A motor assembly includes a motor and sealing member fixed to a frame. The motor includes a stator and a rotor. The stator includes a coil holding portion and a first portion with an annular shape and extending radially outward from the coil holding portion. The rotor includes a magnet and a magnet holding portion located in a first space. The first portion has a first surface in contact with the first space, and a second surface on a side opposite to the first surface. A through hole penetrates from the first surface to the second surface in the first portion. The sealing member is disposed on a side of the stator opposite to the rotor, and is fixed to the frame so a second space between the sealing member and the stator does not communicate with an external space other than the first space.
