Problems solved by technology
[0002] The traditional low-speed and high-speed permanent magnet generators are three-phase power generation windings, that is, three-phase star and Y-shaped connections. When the above connection method cuts the magnetic induction line when the rotor rotates, only two sets of power generation windings do work, that is, the values are equal and the directions are opposite. The other group does not generate electricity (two by two), which greatly reduces the power generation

The invention discloses a novel permanent magnet generator stator structure, which comprises a stator core and two phase power generation windings arranged on the stator core. The stator core comprises 2N slots, N being a positive integer. The two phase power generation windings comprise 2N coils coiled between the adjacent two slots respectively. The front N-1 coils coiled from the first slot are input from the front slots and output from the back slots; the Nth coil is input from the Nth slot, output from the Nth slot and jumped and coiled to the (N+2)th slot, coiled back to the (N+1)th slot and coiled to the (N+2) slot to form the (N+1)th coil; and the back N-1 coils are input from the front slots and output from the back slots.
Description
technical field [0001] The invention belongs to the technical field of generators. Background technique [0002] The traditional low-speed and high-speed permanent magnet generators are three-phase power generation windings, that is, three-phase star and Y-shaped connections. When the above connection method cuts the magnetic induction line when the rotor rotates, only two sets of power generation windings do work, that is, the values are equal and the directions are opposite. The other group does not generate electricity (two by two), which greatly reduces the power generation. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a permanent magnet generator stator structure to improve the power generation efficiency and voltage of the permanent magnet generator. [0004] Technical scheme: in order to achieve the above object, the technical scheme of the present invention is ...
