Abstract
Disclosed are a method of increasing voltage and output power when an electric generator is in slow-speed rotation and an electric generator stator coil circuit. The method comprises that the stator coil of the electric generator is divided into two groups, one group is a main winding, the other group is a secondary winding, the main winding is a winding coil of the electric generator in normal operation, and the main winding and the secondary winding are in series connection via a control circuit. When the electric generator is in slow-speed rotation, the control circuit enables the main winding and the secondary winding to be connected in series, at this time, the electric generator stator coil is increased, thereby the internal resistance is increased, the electric current and the voltage of the electric generator is raised, and the output power of the electric generator are increased, when the electric generator is in normal speed rotation, the control circuit enables the main winding and the secondary winding to be divided, the secondary winding automatically quits, and then the electric generator is in normal operation.
