Abstract

The nutation motor, a new type of stepping motor we developed, features a simple structure, high resolution, and speed reduction, and operates on electromagnetic power. Our previously developed nutation motor operated on air pressure. We designed an electromagnetic coil based on magnetic field analysis using the finite element method (FEM) and optimized dimensions. The result was an electromagnet having an maximum force of 60N and an electric current of 0.3A. Using this electromagnet, we developed a motor having a maximum torque of 0.67N × m, a maximum rotation of 4.3rpm, and a minimum resolution of 1248step/rev.
