Access this Article
A prototype spherical motor driven by electro-magnets was studied and developed in the previous study. The whole radius is 110[mm], the rotor radius is 50[mm], the maximum torque is 0.06[Nm], and the maximum rotation angular velocity is 6.5[rad/sec]. This paper reports the several investigations to improve the performance of the motor and to decrease its size. In improving performance, the new spherical motor is developed, where 92 permanent magnets are attached on inner surface of the rotor. The new motor outputs about 3 times torque of the prototype. On the other hands, in designing small spherical motor, the specifications of electro-magnet and permanent magnet are examined using an extended simulator for a small spherical motor whose whole radius is 25[mm] and rotor radius is 15[mm].
