摘要： A small-sized motor of the present invention includes a rotor, which, in turn, includes a shaft 7, a laminated core 8 forming salient magnetic poles an odd number and mounted on the shaft 7, windings 9, each being wound around a plurality of salient magnetic poles, and a commutator 10 mounted on the shaft 7. Each salient magnetic pole includes an arm portion 16 and wing portions 17, which are integrated with ends of the arm portion 16 and circumferentially extends symmetrically with respect to the arm portion 16. When core laminations of the laminated core 8 each has a thickness u, the laminated core 8 has a diameter D, and the wing portion 17 has a thickness t as measured at its root in a radial direction, the thickness t falls within the range from 5.5% the core diameter D as an upper limit to the core-lamination thickness u as a lower limit. Thus, it becomes possible to solve a problem of a rotor having an odd number of poles in that vibration is likely to arise, to thereby suppress vibration, while maintaining a feature of the rotor that a large torque can be produced.

摘要： A direct current motor (10) having an armature (28) axially supported between magnetic pole plates (15-16, 17-18, 19-20) having opposing pairs of pole shoes (50-52; 60-62) extending in interdigital parallel opposition with respect to the periphery of the armature between the pole plates adjacent the armature, is energized by direct current through a pair of coils (24, 25) interposed between and connected with the magnetic pole plates. The respective ends of selected pole shoes are connected with pole plates of like polarity magnetic flux and similarly the remaining of pole shoes are connected at their respective ends with pole plates of opposite polarity magnetic flux density. Wiring (69) and electrical current controls (68) connect a DC source (B) to the coils and armature for providing a maximum torque and drive shaft speed with a minimum of ampere drain from the DC source.
