Abstract

A generator with magnetic poles and coils together serving as a stator relates to a mechanical generating apparatus. The generator comprises a housing. The magnetic poles and the coils containing iron cores are fixedly disposed inside the housing. The coils are wound on the iron cores in a concentrated manner, and two ends of each coil are connected with terminals outside the housing. The magnetic poles and the coils together serve as the stator. Each two magnetic poles with the same polarity are disposed on two sides of each coil. At least two groups of the magnetic poles are adopted, and at least two groups of the coils are employed. Each permanent magnet and each iron core are arc-shaped. The magnetic poles and the coils are connected at intervals to form an annular body which serves as the stator to be fixed inside the housing. A rotor, a ferromagnetic metal sheet or a ferromagnetic metal block, is arranged inside the annular body and fixed on a main shaft, and can rotate inside the annular body along the main shaft. The beneficial effects of the generator are that the rotor belongs to ferromagnetic metal without a coil, so that the rotor is simple in structure, small in size and low in mechanical resistance; and the generator has the obvious advantages of energy conservation, high efficiency or the like, compared with a conventional generator with a heavy rotor and grooving iron cores.

Four iron cores are arranged in the described stator, and protruding end is eight, and the equispaced 45° angle forms an annular shape; Described rotor is " ten " font body, and four protruding ends are arranged, and 90 ° of equispaceds are corresponding with the protruding end in the stator, and rotor rotates in the ring-type that the protruding end of stator surrounds.

Described rotor and iron core adopt the stack of multilayer ferrimagnet to make.

Three coaxial linking to each other of uniset, and the relatively staggered hexagonal angle degree of " ten " rotor in each unit, the structure of formation three-phase synchronous generator.

The principle of the utility model basis " magnetic induction line (magnetic flux) always concentrates on the path of magnetic resistance minimum, self-assembling formation closed-loop path " designs.In the utility model: magnetic pole, coil (containing iron core) are fixed, and form stator; Like pole is with respect to the coil both sides of (containing iron core), and Magnetic Phase is anti-; Rotor is between the iron core lug boss.Because like pole is with respect to the both sides of iron-core coil, Magnetic Phase is anti-to make magnetic flux can not form the loop, can only could form the loop under the guiding of rotor.Rotor is in the situation of " ten " font body, and during work, the every rotation 45° angle of rotor can make the direction by the iron core magnetic flux path change once, passes coil and produces induced electromotive force.Simple sinusoidal electromotive of 90 ° of generations of every rotation, a week produces four simple sinusoidal electromotives.

The utlity model has following beneficial effect: magnetic pole, coil (containing iron core) are all stator; Rotor structure is simple, quality is light, volume is little, and without coil, need not brush, magnetic leakage free.When work, the mechanical resistance of generation is little, eddy current is little, it is low to heat up.Therefore, for the generator of the rotor of existing generator heaviness and grooved core, the utility model rotor have significantly energy-conservation, efficiently reach advantage on the function.Because coil and magnetic pole are fixed, electric current can directly be exported, and need not use brush, can guarantee the generator safe operation.The utility model has been broken through the mode of magnetic pole and coil relative motion, has opened up the new technical field of generator.
