“…Because the produced torque is a combination of magnet and reluctance torques, this motor type can be called as a hybrid motor. The rotor can be designed in many different structures to provide both magnet and reluctance torques [1][2][3][4][5][6][7][8][9][10][11].…”

-This paper presents a hybrid motor prototype convenient to modify the magnet and reluctance torques. The rotor of the prototype consists of magnet and reluctance parts, so the generated torque includes both magnet and reluctance torques. A considerable feature of the motor is that the ratio of the magnet and reluctance parts can be modified on the rotor and the rotor hybridization ratio can be varied. Another important point is the mechanical angle between the parts changed by means of the suitable construction of the parts on the rotor shaft. Finite element (FE) analysis was carried out for the proposed motor and static torque measurements were realized. The FE results were compared with the experimental results. Average torque and maximum torque values were obtained and three dimensional 3-D graphs were formed by using the experimental data. It is possible to make different combinations by changing the parts and the angle between the parts due to the proposed motor. So the magnet and reluctance torques are modified and different combinations give different torque behavior.

“…The two-part rotor was investigated in more detail in [4] by Chalmers et al, wherein a set of base equations was established to describe this motor dependent on the displacement angle between the two rotor parts. Unfortunately, the authors of [1] and [4] discarded the possibility to set any desired displacement angle in their following contributions [5], [6], [7] partly due to the fact that these machines don't show the same characteristics in motoring and generating mode.…”

 Abstract --This paper examines synchronous machines, whose excitation axis and reluctance axis can have an arbitrary angle. Basic equations for this machine type are set up and control strategies for maximum torque are derived. By using a normalized representation, it will be shown that machines with displacement angles of about 60° need up to 10% less permanent magnet material than conventional machines while yielding comparable motor performance.

“…To achieve field weakening or control in PM machines by eliminating the effects of d-axis current injection have been of great interest in the literature. New alternative topologies with field weakening or hybrid excitation introduced in the literature so far to eliminate this problem are from a machine perspective [1][2][3][4][5][6][7][8][9] and meant especially for radial flux machines. However, there exists no axial flux machine with true field weakening capability in the literature.…”

Abstract1 -Performance evaluation of an axial flux surface mounted permanent magnet (PM) field controlled TORUS type (FCT) disc machine is presented in this paper. This new machine is an axial flux configuration with true field weakening capability since the flux is controlled by the DC field winding rather than opposing the magnets. Structure and operating principles are summarized in the first section. Next, 3D Finite Element Analysis (FEA) including no-load and on-load characteristics and back EMF variation for various armature currents and DC field current are explored. Furthermore, torque characteristics of the FCT machine for different field currents are explored. Minimization of cogging torque calculations and the effect of skewing the magnets are also examined.
