winding in the stator and for the current excited synchronous machines they need additionally the brush-type exciter system for the rotor field winding. As well is known the distributed winding is characterized with large end-winding length high copper losses and high production costs compared with the tooth concentrated windings.
We claim 1. A process for manufacturing a rotor or stator of an electric machine out of one piece congruent and asymmetrical sheet metal blanks (A B) which are cut out from rolled sheet metal (1) with a predominant magnetic direction (2) and are stacked adjacent one another to form a rotor or stator lamination bundle wherein adjacent sheet metal blanks of the lamination bundle are cut out
A motor-generator includes a rotor that rotates about an axis of rotation and a stator that is stationary and magnetically interacts with the rotor. The rotor is constructed of two spaced apart rotor portions having magnetic poles that drive magnetic flux across an armature airgap formed therebetween. An armature located in the armature airgap has a substantially nonmagnetic and low

An induction motor is an alternating current rotating asynchronous motor generally consisting of a stationary primary winding coil or stator and a rotating secondary coil/armature or rotor. The device converts electrical energy to mechanical energy by use of the electromagnetic induction. The rotating electromagnetic field created by the electrical current in the stator coil induces current
needs to vary direction according to the rotor position and hence the stator windings need to employ AC excitation 3 . Fig. 1 illustrates the configuration of transverse flux machine with one active side 3 . The rotor consists of two arrays of permanent magnets mounted on the core back of laminated steels. The stator armature winding
an armature or rotor made of permanent and in many cases neodymium magnets and a stator with windings that create a magnetic field when energized. The rotor’s magnets and stator’s windings provide the rotation of the motor. They attract each other with opposite poles and repel each other with the same poles.
A low inductance electrical machine (1) that may be used as an alternator or motor with low armature inductance is disclosed. Arrangements of complementary armature windings (40A 42A) are presented in which the fluxes induced by currents in the armature windings (40) effectively cancel leading to low magnetic energy storage within the machine (1).

In all the low-energy ferrite PM apparently did not suit for FSPM since the space in the stator was quite limited to accommodate armature windings stator teeth and PM poles. It should also be noted that the risk of demagnetization for ferrite FSPMs was high because the low magnetic energy PM would face directly to reactive field from the
