Claims (1)
に複数の永久磁石が互いに離隔して固定されてお
り、このヨーク側壁の近傍にヨークの回転により
各永久磁石と順次磁路を形成するコアが配設され
ているとともに、このコアに信号発生用コイルが
巻回されている信号発生装置において、前記永久
磁石群のうち少なくとも一つは、相隣接する他の
永久磁石よりも磁束密度が高くなるように構成さ
れていることを特徴とする信号発生装置。 A plurality of permanent magnets are fixed at a distance from each other on the side wall of a yoke that is formed into a roughly bowl shape and is rotated, and a core that forms a magnetic path with each permanent magnet in sequence as the yoke rotates is located near the yoke side wall. In the signal generating device in which a signal generating coil is wound around the core, at least one of the permanent magnet groups has a higher magnetic flux density than other adjacent permanent magnets. A signal generator characterized in that it is configured as follows.
