Undirected generator set

An undirected generator set comprises magnetic poles, a coil, a linear magnetic commutator, a binding post, an upper wind cup group, a lower wind cup group, an upper wind cup group bearing, a coil fixing bearing, a shaft rod, a lower wind cup group fixing wire rod, and a base. The undirected generator set is characterized in that the magnetic poles are fixed in the upper wind cup group; the upper wind cup group is movably fixed on the shaft rod through the upper wind cup group bearing; the coil is movably fixed on the shaft rod through the coil fixing bearing; a lower wind cage is fixed on a lower wind cage wire rod; the linear magnetic commutator is fixed on the shaft rod; and one end of the lower wind cup group fixing wire rod is fixed on the coil, and the other end is connected with the linear magnetic commutator through a brush. Current is exported from the binding post. The stress surfaces of the blades of the upper wind cup group and the lower wind cup group are opposite, so that the upper wind cup grou
