Inset types of permanent magnet bearingless motor
Masahide Oshima
In the previous chapter a method for controlling radial force generation, when considering the armature reaction, was described. The radial suspension force can be controlled without interference between the components in two perpendicular axes. With the correct design of the decoupling controller and rotor, suspension force generation under torque-generating conditions can be further enhanced.
In the inset type of permanent magnet motor, the armature reaction is quite high and advantage can be taken of this to enhance the suspension force. The key is the construction of a precise and accurate decoupling controller with the identification of radial force parameters.
