ELECTROMAGNET AND ELECTROMAGNETIC COIL ASSEMBLY

摘要

An electromagnet may comprise a pole piece and a coil assembly. The pole piece may be monolithically formed of a magnetically susceptible material and have a channel structure and a first flange member. The channel structure may have an annular inner side wall, an annular outer side wall and an annular end wall that fixedly couples the inner and outer side walls to one another on a first axial end of the pole piece. The channel structure may be open on a second axial end of the pole piece that is opposite the first axial end. The first flange member may be coupled to an end of one of the inner and outer side walls on the second axial end and extend radially from the channel structure. The coil assembly may be fixedly coupled to the channel structure between the inner and outer side walls.
