Abstract

PURPOSE:To lower the height of a stepping motor by increasing the number of magnetic poles of a magnet rotor and placing and providing armature coils or salient-poles of armature to both ends of the magnet rotor. CONSTITUTION:Both ends of a magnet 5 are magnetized to N and S magnetic poles as indicated on the figure. An annealed steel disc 3 made by bending a plurality of magnetic poles 3(a), 3(b), 3(c),... and, by press working is adhered to the left of the magnet 5. Each of the magnetic poles 3(a), 3(b) and 3(c) is magnetized to N pole. U type of magnetic path open ends of the magnetic cores 6 and 7 are opposite to both sides of a magnet rotor F through a clearance. And, the exciting coils 8(a) and 8(b) are loaded into the magnetic cores 6 and 7. In this manner, the height of a motor can be lowered by increasing the number of magnetic poles 3(a), 3(b), 3(c),... of the magnet rotor F and placing and providing the exciting coils 8(a) and 8(b) to both side of the magnet rotor F.
