ABSTRACT:
In a rotary pulse motor including: a cylindrical stator made of magnetic material; a cylindrical rotor made of magnetic material and inserted concentrically into the cylindrical stator and being rotatably supported; slit-like grooves formed at a regular angular pitch P/2 in a peripheral portion of the cylindrical rotor, teeth formed between the slit-like grooves permanent magnets inserted into the slit-like grooves and so arranged that polarities of the teeth are alternately inverted; magnetic poles formed at a regular angular pitch in the cylindrical stator facing to the teeth at a constant air gap, and coils provided on the cylindrical stator so as to a generate magnetic flux through the air gap, the cylindrical stator consists of two cylindrical members arranged in the axial direction of the cylindrical rotor and the magnetic-poles include two rows of magnetic poles formed on the cylindrical stator, the magnetic poles in the respective rows being angularly shifted from each other a predetermined pitch of P/2.
