摘要：A canned motor comprising a stator securing concentratedly wound coil aroundsalient poles and being provided outside of a tubular member (5) made of a nonmagneticmaterial, and a rotor (8) provided inside of the tubular member for driving an operatingshaft such that it operates an objective member reciprocally, is further constructed suchthat permanent magnets (4) alternately magnetized into a number of pole-pairs arearranged along the surface of each salient pole of a stator core at a constant pitch, whilea number of induction teeth are formed along the circumference of the rotor at a pitchequal to the pitch of the pole-pairs of the permanent magnets, and the differencebetween the total number of the induction teeth and the total number of the pole-pairsof the permanent magnets is made equal to an even number. Then it operate as a pulsemotor by exchanging the excitation of coil successively.
