| 摘要 | PURPOSE:To obtain a compact motor inexpensively by composing a converter having switching means for converting the polarity of a pole upon rotation of a rotor and rectifying means by a special method, thereby simplifying the converter. CONSTITUTION:A converter is disposed in the phase difference of 120 deg. with respect to a slider 50 having two proximity concentric circles which are divided into four sets of 90 deg. at the peripheral angle upon rotating integrally with the rotational shaft 40 of a permanent magnet 30. The converter is further composed of commutators 61-64 having 3 paris of brushes 60 slidable contacting at one of the pairs with the one of the concentric circle and at the other with the other of the concentric circle, and four sets of sliders 50 connected at the two adjacent sets in a direction from one concentric circle to the other and at the other two sets in a direction from the other concentric circle to the one concentric circle. | ||||||
