Since 1 is rotated at high speed, if there is an imbalance in the rotating body, severe vibration will occur. Therefore, it is essential to correct the unbalance of the rotating body.
The outer periphery of the laminated core 14 is shaved while performing a test with a balance tester or the like. And, if the amount of unbalance is terrible, it must be corrected several times, but the ratio indicating the extent to which the unbalance is corrected is called the orthogonality rate. For example, let A be the one that could be corrected by the automatic balance corrector, and B be the one that could not be corrected by the automatic balance corrector and that was manually corrected, so the orthogonality rate = [A / (A + B)] × 1
It becomes 00 (%).

能のバラツキを生じていた。As is well known, in order to correct the imbalance of the rotating body, it is necessary to make a dynamic balance, that is, to obtain a dynamic balance. However, the imbalance in such an electric blower is
Static unbalance
e), especially the static imbalance of the rotor during manufacturing, that is, the total unbalance when the rotor core components, the laminated core, the commutator, the windings, the insulating paper, the varnish, etc. are attached to the rotating shaft. In spite of the large balance (this is referred to as the initial unbalance in this specification), the conventional electric blower structure corrects all unbalances by cutting the outer periphery of the laminated core. Since there is an upper limit on the amount that can be cut at one time, the orthogonality ratio for unbalance correction is low, and there is variation in performance due to overcutting the outer periphery of the laminated core.
