摘要： A brushed motor includes a rotation shaft, a commutator including a plurality of segments separated by a plurality of undercuts arranged at unequal intervals, an armature, a plurality of permanent magnets, a voltage equalizing line, a positive electrode brush, and a negative electrode brush. When Pz is the number of the permanent magnets and N is the number of the segments, a relationship of N=Pz(K−0.5) is satisfied. Pz is an even number that is greater than or equal to four. K is a constant and is a natural number that is greater than or equal to two. The plurality of undercuts includes at least one set of undercuts arranged at an undercut interval that differs from a reference angle θz. The reference angle θz is specified by a relational expression of θz=(360 degrees/Pz)±(360 degrees/2N).

摘要： A power conversion and distribution system. In one embodiment low voltage source components convert a high voltage AC power source to a relatively low voltage supply and provide a direct current output. First superconductor wires carry current from the low voltage source components to a load, and second superconductor wires carry current from the load to the low voltage source components. Individual ones of the first wires are grouped with individual ones of the second wires so that wires connected to carry current in opposite directions are in such sufficiently close proximity that additives of self-fields generated by individual ones of the wires during power transmission result in reduction of the magnetic fringe field generated, thereby increasing the current carrying capacity of the wires.

摘要： A brush direct current motor has a stator with a plurality of coils that correspond to a number of stator windings, a rotor with a number of poles, and a commutator. The commutator is connected to a first terminal of a direct current power source to convert the power into N phase alternating current. One end of each stator winding is connected to a respective phase of the alternating current via a brush and the other ends of the stator windings are connected to the second terminal of the direct current power source.
