Abstract
An improved cylindrical linear motor is capable of being more easily assembled by changing the constructions of a primary iron core and a primary coil and significantly preventing an over-heating of the primary coil. The motor includes primary toothed sections formed of stacked steel plates, with the primary toothed sections being spaced-apart from one another, a supporting member formed to support 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 within the primary iron cores.
Claims4
A cylindrical linear motor having individually toothed laminated primary cores, comprising:
- a primary iron core assembly having a yoke and primary toothed sections separate from the yoke;
- a supporting member supported by the primary iron core assembly and having
- a pipe having a predetermined length;
- a plurality of right-angled spaced-apart engaging arms fixed to an outer circumferential surface of the pipe;
- and
- a plurality of first engaging holes formed in each engaging arm;
- coils wound onto the supporting member and the primary iron core assembly;
- and
- a stationary secondary iron core inserted into the primary iron core assembly.
