Abstract
Disclosed is a low temperature rise excitation generator, comprising three windings and a plurality of magnetic poles, wherein the windings are composed of a plurality of coils; and the magnetic poles drive the direction changing of the current inside the coils via rotation to adjust the phase difference between two adjacent coils. When the directions of the currents inside two adjacent coils are opposite, the head of a coil that has an internal current with direction toward left is connected with the tail of a coil that has an internal current with direction toward the right. In addition, the head of the coil that has an internal current with the direction toward the right is connected with the tail of a coil that has an internal current with direction toward the left. The coil that has an internal current with unchanged direction is connected with the adjacent coil. By changing the connecting modes of two adjacent coils, the internal currents of the two coils are not offset when the current directions of two adjacent coils are opposite, thereby decreasing the energy loss and working temperature and raising the generating efficiency.
