Study on Structure for Increase of a Transmit Torque on Magnetic Harmonic Gear with Stackable Structure

Article Preview

Abstract:

The magnetic harmonic gear has been studied because of its high magnet use efficiency. However the magnetic harmonic gears are difficult to assemble. So, a new type of the magnetic harmonic gear was proposed. This magnetic gear has the stackable structure and is assembled easily. Thus far, it was studied its characteristics. In this study, we readjust its structure to step up its maximum transmit torque. The magnetic gear has parts which is constituted an iron plate and a segment magnet. In the past, it has never studied the ratio of iron to magnet. Therefore, we analyze the effect when they are changed the ratio of the iron to the magnet by simulation. We made the model which maximum transmitted torque is largest in the simulation. Then, we verify that the maximum transmitted torque is really improve. But it did not follow the results of the simulation. We discuss the reason of discrepancy.
