<p>PROBLEM TO BE SOLVED: To provide an electric blower which suppresses temperature rise.SOLUTION: An electric blower comprises: a rotor 17 which includes a shaft 3 including a commutator 15, a rotor core 13 formed by superposing a plurality of thin magnetic steel sheets 12, and attached to the shaft 3, and rotor windings 14 applied on the rotor core 13; and a stator 11 which includes a stator core 9 positioned in an outer periphery of the rotor 17, and formed by alternately superposing a plurality of large magnetic steel sheets 20 and small magnetic steel sheets 21 both of which are different in shapes, and stator windings 10 provided on the stator core 9. A surface area of the stator core 9 and an area contacting air sucked by the electric blower are increased by employing the stator core 9 in which a plurality of the large magnetic steel sheets 20 and the small magnetic steel sheets 21 both of which are different in shapes are stacked, and thus, cooling efficiency can be improved.</p> |
