PROBLEM TO BE SOLVED: To obtain a rotary linear DC motor that is improved in characteristics and can move linearly, rotationally and spirally. SOLUTION: In the rotary linear DC motor, a rotary winding 14 and a linear winding 13 are applied to a stator core 12 to form a stator 10, N-pole magnets 15 are arranged at every other pole in the circumferential direction and the axial direction on the surface of a cylindrical needle core 8, and S-pole magnets are arranged at every other pole in the circumferential direction and the axial direction, in positions where the S-pole magnets are arranged at every other pole of the N-pole magnet 15 in the circumferential direction and the axial direction to form a needle 9; and a three-phase AC is applied to the rotary winding 14 to rotate the needle 9, or a DC is applied to the linear winding 13 to linearly move the needle 9, or the three-phase AC and the DC are applied to the winding 14, 13, respectively, to spirally move the rotary linear DC motor.
