Technical field:
The utility model relates to the technical field of generator, specifically a kind of permanent magnet generator that is applied to all kinds wind power plant and other generating equipments.
Background technology:
The cored permanent magnet generator that multiple permanent magnet generator is formed by silicon steel sheet in the prior art, their defective is that 1. staring torques are big; 2. copper loss, iron loss are arranged, and magnetic flux density reduces thereupon; 3. bulky, weight is big, material and processing cost height; 4. turning moment is big; 5. owing to be the internal rotor form, it is inconvenient to bring output shaft to install; 6. overload capability is poor, because it is columniform, thus poor radiation, temperature rise.Because above shortcoming is not suitable for wind power plant with production cost, power generation performance and the installation that directly has influence on generator.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved permanent magnet generator, can overcome the some shortcomings that processing cost height in the prior art, turning moment are big, be not suitable for wind power plant
To achieve these goals, the technical solution of the utility model is: a kind of permanent magnet generator, it mainly comprises upper and lower end cap, central shaft, with the armature body that links to each other with central shaft, it is characterized in that: link to each other by upper and lower bearing between upper and lower end cap and the central shaft, the two ends of armature body are provided with coil, be provided with upper and lower permanent magnetism yoke between the upper and lower end cap symmetrically, be provided with corresponding upper and lower multipole permanent magnet between the upper and lower permanent magnetism yoke, the position of upper and lower multipole permanent magnet is corresponding with coil position.
External rotor of being made up of the upper and lower end cap of polygonal hub-type of the present utility model and the upper and lower multipole permanent magnet that is installed between the upper and lower end cap are combined into one during use, the coreless armature stator (being compressed to one by multinomial coil, armature body and central shaft forms) of disc type is equipped with in the centre, upper and lower multipole permanent magnet is the cutting stator armature coil magnetic line of force when rotated, thereby in winding coil, induce electromotive force, send electric current, obtain required power.It is simple in structure, compact, reasonable, manufacturing cost is extremely low, production and processing simple, improved production efficiency, increased magnetic field intensity technically, reduced staring torque significantly, improved rotating speed, for wind power plant provides a kind of novel external rotor coreless permanent magnet generator.
