Cylindrical linear motor having individually toothed laminated primary cores

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a cylindrical linear motor which overcomes the aforementioned problems encountered in the conventional art.
It is another object of the present invention to provide an improved cylindrical linear motor which is capable of more easy assembly by changing the constructions of a primary iron core and coils and significantly preventing an over-heating of the coils.
To achieve the above objects, there is provided a cylindrical linear motor which includes a plurality of primary toothed sections formed of stacked steel plates, with the primary toothed sections being spaced-apart from one another, a supporting member supporting the primary toothed sections, coils wound onto the supporting member and between the primary toothed sections, a yoke formed of stacked steel plates and engaged to the primary toothed sections between which the coils are wound, and a secondary iron core inserted into the primary iron core having the yoke and the primary toothed sections.
Additional advantages, objects and features of the invention will become more apparent from the description which follows.
