PURPOSE:To make a motor having an output torque without ripples or a generator for producing DC output proportional to the numbers of revolutions by installing an armature coil perpendicular to the direction of rotation of a magnet rotor and providing holes outside the armature. CONSTITUTION:When an armature coil 5a is energized, the direction of magnetic flux generated is shown by arrows 23a and 23b. And magnetic flux at N-pole of a magnet rotor 4 is shown by arrows 24a and 24b. The magnetic flux shown by the arrows 23a and 24a increases because of the addition of them at the right hand side of the lower part of a magnetic substance, and decreases because of the subtraction of one from the other at the left hand side. Therefore, the rotor 4 generates a driving torque in the direction shown by arrow D. By this, a motor produces an output torque without ripples, and a generator produces an output voltage not having ripples and proportional to the revolution speed. |
