Abstract: A magnetic gear can transmit a torque and a motion without the
contact by the magnetic force. Today a magnetic gear are studied about
increasing transmit torque and decreasing cogging torque. The property of the
positioning is another significant property in use of a motion transmission by
magnetic gears. Therefore it is important to measure the positioning property.
The purpose of this research is to check the relationship between the number of
the magnet of the gear and positioning property. Then we have developed three
types of gear which have a different number of teeth severally. By using the
developed three types of gear, the average and the standard deviation are
calculated from experimental results. We reveal the influence of the number of
the teeth to positioning property in several operation conditions.
Keywords: Magnetic gear, positioning accuracy, number of teeth, magnetic flux leakage
