Homo-polar machine for driving motor for rail or land vehicle, has armature system, with two axially spaced pair of like poles rotating at certain degree and stator system is provided, which has accurate stator laminated core

摘要

The homo-polar machine (1) has an armature system, which has two axially spaced pair of like poles (3,4) rotating at 90 degree. A stator system is provided, which has an accurate stator laminated core (2) and a stator piece (7), which is formed to concentrate magnetic flux on the laminated core for producing an electromotive force, where the magnetic flux is driven by an excitation coil (6).
