Abstract

PURPOSE: To cause a strong vibrating force and accurately measure the vibration strength characteristic of an impeller of high rigidity, by providing AC coils of different polarity at the peripheral part of the impeller and overlapping a DC coil with the AC coils.
CONSTITUTION: Two magnets 2, 3 are placed near the central plate 11 and side plate 12 of a radial impeller 1. AC coils 5, 6 of different polarity are provided around the ends of the magnets 2, 3. The other ends of the magnets are connected to each other. A DC coil 4 is mounted around the connected ends of the magnets. A strong vibrating force can be caused by the synthesized magnetic flux of the coils out of contact with the impeller.
