<p>Provided is a contactless electric power supply device that supplies electric power in a contactless manner to coils of a linear motor device provided with a track member, a movable body that is mounted to the track member, a plurality of magnets that are arranged in the track member in a row, and the coils. The contactless electric power supply device includes two sets of contactless electric power supply units which respectively include an electric power supply electrode plate extending in a movement direction of the track member and an electric power reception electrode plate provided to the movable body to face the electric power supply electrode plate, and which realize contactless supply of high-frequency electric power, a high-frequency power source unit that supplies high-frequency electric power between the electric power supply electrode plates, and an electric power modification unit that modifies the high-frequency electric power supplied to the electric power reception electrode plates in a contactless manner and supplies the resultant modified electric power to the coils. According to this, it is possible to provide a contactless electric power supply device which is capable of performing contactless electric power supply to the coils on a movable body side of the linear motor device with a large electric power supply capacity and high electric power supply efficiency, and which is not expensive without an effect of the contactless electric power supply on generation of a driving force.</p> |
