Abstract

The authors have developed a spherical motor called as 14-12 spherical motor. The 14-12 spherical motor is composed of spherical rotor with permanent magnets, stator of spherical shell with electro-magnets, excitation electric circuit of electro-magnets, and power supply. The motor has two kinds of rotation axes and totally six rotation axes. The previous studies presented its structure, working principle of rotation by five-phase alternative current (AC), and experimental evaluation of rotation torque and cogging torque around one of rotation axes. This study evaluates the rotation torque around another rotation axis and cogging torque in detail to grasp the basic rotation performances of the 14-12 spherical motor.
