Abstract

PURPOSE:To make the turning torque greater by providing two stators to both the inside ans outside of the rotor magnet. CONSTITUTION:The cup-wise rotor 5 consists of the rotary shaft 1, disk 2, cylinder 3 and ring-wise magnet 4, the stator cores 10, 12 are provided to the inside and outside of the rotor, and the exciting coil 13 is winded around the outside core 12. In this way, a greater magnetic force acts on the rotor, a greater torque and a good rise are obtained, the moment of inertia can be made less since the mass of rotor is little.
