The permanent magnet machine further includes a design for a rotor lamination which provides sixteen magnet slots and eight slot connecting holes. The slot connecting holes join the magnet slots in pairs, which provide easy access to the magnets inserted in the rotor. The rotor design further provides a series of rotor holes located between the magnet slots which, with the slot connecting holes, provide for insulation of the machine from unwanted magnetic flux.

[ What is claimed is:] [1.] A rotor and stator combination for use in a permanent magnet machine operating from a three-phase power supply, comprising:a rotor having sixteen magnet slots;a magnet inserted into each magnet slot;a stator having eighteen teeth; andthree groups of coils wound around the teeth of the stator, each group of coils being connected to one phase of the three-phase power supply, and each group of coils including a first, second and third coil wound around three stator teeth;wherein the first and second coils are of the same polarity and are separated by a single stator tooth; andwherein the third coil has the opposite polarity of the first and second coils and is positioned on the stator opposite the tooth separating the first and second coils.
