Title:
電磁結合を備えた液体攪拌機
Document Type and Number:
Japanese Patent JP4495346
Kind Code:
B2
Abstract:
The stirrer comprises a driving magnetic portion (13) and a driven magnetic portion (14). The driven portion is for placing on the bottom of a receptacle (51) containing a liquid to be stirred. The driving portion (13) is controlled so as to drive the driven portion (14) in rotation about a predetermined axis of rotation (81) by means of magnetic coupling with the driving portion. The stirrer is characterized in that the driving and driven portions are configured in such a manner as to encourage the field lines (15) that result from the magnetic coupling to extend substantially perpendicularly to the axis of rotation in the vicinity of the driven portion. Axial attraction between the driving and driven portions is thus considerably reduced for given torque transmission to the driven portion, such that the driven portion (14) and the bottom of the receptacle (51) are subject to less wear during rotation of the driven portion.
