To obtain a power conversion device in which a board to be mounted is downsized by downsizing of elements or an arrangement configuration of the elements, a motor including the same, an air conditioner having the motor incorporated therein, and a ventilation fan having the motor incorporated therein. Included are a printed circuit board 1, whose mounting surface is opposite to an annular surface formed by an annular stator 3 that constitutes a motor 61, arranged to be separated from the annular surface with a predetermined distance, and mounted with a Hall element 6 that detects a rotation position of a rotor 16 of the motor 61 on a mounting surface on a side of the stator 3; an inverter IC 2 that is mounted on the mounting surface on the side of the stator 3 of the printed circuit board 1 to supply a high-frequency current to the stator 3; and an overheat detection unit 14 that is mounted on the mounting surface on the side of the stator 3 of the printed circuit board 1 and detects an overheated state of the inverter IC 2. When the overheat detection unit 14 detects an overheated state, the inverter IC 2 restricts or stops a current to be supplied to the stator 3. |
