<p>PROBLEM TO BE SOLVED: To provide a small-sized high-output high-efficiency motor which suppresses the induced voltage in an electric motor and reduces the iron loss, when the rotary shaft rotates by external force. SOLUTION: This is a motor which is equipped with a rotor for which a first rotor part 2 equipped with a permanent magnet 6 and a second rotor part 3 which is provided with a magnetic flux screen groove so as to posses saliency are coupled witch each other in the direction of the rotary shaft, and a stator 21 which generates a field for driving the rotor by supplying it with a current, and in which the rotary shaft of the rotor rotates by an external rotation means, and a high-output and high-efficiency motor, for which the quantity of permanent magnets is reduced by making a part of the rotor a reluctance motor, and the generation of induced voltage is suppressed and iron loss is reduced.</p> |
