Rotor of electromagnetic drive shutter
专利汇可以提供Rotor of electromagnetic drive shutter专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the flatness of sector rings disposed with conductor coil patterns by forming said sector rings with thermosetting resin and coating their surfaces with a photosetting resin.
CONSTITUTION: Power is supplied to the conductor coil patterns disposed on sector rings 2 to turn the sector rings in the magnetic field created in the clearance between stator magnets 1a, 1b and a stator yoke. And this is such an electromagnetic drive shutter that causes opening and closing motion of the sectors, wherein the sector ring substrates are formed by a thermosetting resin having heat resistance and are coated with a dry film layer to be cured by ultraviolet rays after the formation of coil patters; said layer is cured by irradiating ultraviolet rays with the aid of glass as guides. After this, further the substrates are heat-treated to accelerate the polymerization of the coating layer and eliminate secular change. In the said manner, the flatness necessary for operation in the narrow clearance is obtainable.
