Abstract

PURPOSE: To obtain an electric blower with no circular vibration of the stator core, no resonance within the range of run and with less noise by making the raio of the number of natural vibration of the stator core to the number of stationary rotation multiplied by the number of rotor slots less than the specified value.
CONSTITUTION: The stator core 3 is rectangular-shaped, the grooves 32 and 33 are symmetrically provided to each side of the circumference of the coil respectively, and the ratio of the number of natural vibration of the stator core 31 to the rated number of rotaion multiplied by the number of rotor slots is made less than 1/60. By this way, the circular vibration of the stator core 31 is prevented, resulting in no resonance within the range of run bacause the number of natual vibration of the stator core 31 is made less than the rated number of rotation. Also the depth of the grooves 32 and 33 can be reduced by half since those are symmetrically provided to each side respectively.
