Abstract

PURPOSE:To improve the electromagnetic driving efficiency of an electromagnetic driving device by providing the first and second yokes on the surfaces of an armature facing to each other providing permanent magnets at the gaps of the yokes, and thus utilizing simultaneously both attracting force and Lorentz's force. CONSTITUTION:The first and second -shaped yokes 5 and 6 are disposed to confront the magnetic pole surface of the armature 2. Permanent magnets 3 are respectively disposed at gaps between the first yoke and the second yoke. The contacting surface of the permanent magnet 3 with the first yoke 5 is formed larger than that of the magnet 3 with the second yoke 6 at a normal time. With such constitution, the armature 2 is moved rightwardly when a current is flowed through a coil. Thus, both the magnetic attracting force and the Lorentz's force can be simultaneously obtained, thereby producing the driving force for the large armature.
