FIELD: electricity.SUBSTANCE: linear oscillating drive comprises a section generating a magnetic pole, which includes an electromagnet, a base and magnetic blocks. Each magnetic block includes a magnet pulled or pushed by the electromagnet for making a reciprocal motion. Elastic suspensions support magnetic blocks. The pair of connecting springs are connected with both sides of magnetic blocks. Each of elastic suspensions includes upper and lower stretching sections and elastic flat sections, which are fully provided accordingly between upper stretching sections and lower stretching sections. On continuous sections, between accordingly upper stretching sections and elastic flat sections there are concave sections formed. Each of concave sections is bent towards the magnetic blocks. When magnetic blocks make a reciprocal motion, concentration of stresses on continuous sections may be reduced with the help of concave sections. Therefore, it may be possible to prevent damage of elastic flat sections without increase in size.EFFECT: prevention of connection plates damage without increase of electric drive size.4 cl, 9 dwg |
