<p>The invention relates to an electric machine of simple and economical construction which can be quickly and easily assembled on automatic lines for mass production. Moreover, the inventive machine can be easily disassembled and recycled and it is provided with reduced dimensions for enhanced performance. Said electric machine (1) is characterised in that the stator (2) comprises several stacked, magnetic, annular yokes (20) having spacers (5) disposed therebetween. Each yoke (20) comprises two identical rings (22) which are assembled back-to-back so as to define a closed annular housing (23) therebetween which receives an electric coil. Each ring (22) consists of an annular wall (27). At least one lateral wall (24) extends radially from the annular wall and one of the pins (25) forming one of the poles (21) extends axially from said lateral wall. The rings (22) can be produced by means of moulding using a magnetic sintered metallic powder</p> |
