Problems solved by technology
[0007] Due to the mutual interference of the electromagnetic coils, the aforementioned electromagnetic core will cancel a part of the electromagnetic force, thus requiring a larger coil to meet the actual requirements of the electromagnetic clutch in use, resulting in a larger volume and size.
At the same time, due to the lead holes or grooves on the friction plate, stress and fatigue will occur after long-term friction and use, and cause gaps or cracks, thereby reducing the life of the friction plate and the overall electromagnetic clutch
In addition, this form and structure lead to more materials used, high manufacturing cost, and many manual factors in the process part, which is not conducive to large-scale production and fine processing

Abstract
The invention relates to oppositely-arranged iron cores and a manufacture method thereof, which aim at providing an electromagnetic iron core device and a manufacture method of the electromagnetic iron core for a clutch of a brand-new structure. The oppositely-arranged iron cores comprise iron core grooves (12 and 13) which are oppositely arranged on the electromagnet iron core body (11) along the axial direction, iron core grooves oppositely arranged on the iron core body in direct-stretching mode and iron core grooves oppositely arranged on the iron core body in direct rotary pressing mode. The oppositely-arranged iron cores and the manufacture method thereof are used in production and manufacturing of fan clutches.
