Abstract
PURPOSE: To improve efficiency of a motor by forming a layer of material with higher electric conductivity than the material of an eddy current on the surface facing the magenetic pole of the eddy current composed of a magnetic substance.
CONSTITUTION: When power is given to a motor 2, an eddy current cylinder 5 rotates. When direct current is applied to a coil 13 in this state a click 6a is maggetized into an N pole and a click 6b is magnetized into an S pole. Therefore, the magnetic flux starts from the click 6a, crosses a layer 7 of high electric conductivity, pierces an eddy current cylinder and reaches the click 6a again through the layer 7, the cick 6b, a york 11. Therefore, eddy current produces on the eddy current cylinder 5 and the layer 7 and crossed magnetic poles 6 rotate. The rotation of the crossed magnetic poles 6 is transmitted to an output shaft 9. At this time, the layer 7 is of small resistance, eddy current runs well and efficiency is improved. Speed control at a wride range can be carried out by regulating the current flowing through a coil 13.
