MINIMUM SIZE TYPE SPHERICAL MOTOR

摘要

A minimum size type spherical motor of the present invention comprises a fixing unit, a rotating unit (20), a guide tool unit, and a center shaft (30). The fixing unit comprises a permanent magnet which forms a magnetic loop. The rotating unit (20) outputs torque by using Lorentz force generated by a magnetic field which is generated in a gap of the fixing unit (10) and applied current. The guide tool unit guides output torque to a desired direction when force is applied to the rotating unit (20) and generates a signal for feedback control. The center shaft (30) is connected to the rotating unit (20) to output the torque generated in the rotating unit (20). The present invention is provided to use the Lorentz force according to the principle of a voice coil, thereby outputting second induced decoupled linear torque and performing high accuracy and usability of control. The present invention is provided to apply a gimbal type guide tool in which a hall effect sensor is applied, thereby improving the availability of the inner space of a motor and the availability in a military field.
