Background technology
The present invention, obtained national patent mandate the applicant, application number is, on the basis of " long rectangle strong magnet, the long rectangle iron-core-free induction coil composition motor " of 2013206379864, by stator coil, rotor field by required progression redistribution, forms and be made up of radial magnetic field and radial iron-less core coil, export or input generator or the motor of 50 hertz of three-phase alternating current electric operations.
Summary of the invention
The present invention relates to the 50Hz three phase alternating current motor of a kind of radial magnetic field and radial iron-less core coil composition, it is characterized in that, it is the rotor by radial magnetic field specific distribution, the stator cutting rotor magnetic line of force of radial iron-less core coil specific distribution, motor stator is by cylindrical motor shell and can installs specific distribution coil, be made up of the macromolecular material skeleton of rectangular channel, rotor is by motor shaft, the cylindrical mild steel skeleton by long rectangular channel can installing specific distribution magnet or magnet exciting coil forms, the running part of rotor is by the bearing that the end cap at motor housing two ends and end cap connect with armature spindle, bearing box forms, form the motor of certain number of poles, the different iron-core less motor of various progression can be formed such as, 2 grades, 4 grades, 6 grades, to n level motor, its rotating speed can be corresponding with conventional synchronization motor, namely per minute, 3000 turns, 1500 turns, 1000 go to, 3000 transfer to 2 ∕ n turns.
The technical solution adopted for the present invention to solve the technical problems is, stator is in cylindrical metal case, be close to inwall and one circle be installed by specific distribution requirement, there is the macromolecular material skeleton of many long rectangular channels, many groups stator coil that sizing makes is put in the long square groove of each specific distribution, after drawing, connecting each coil lead, fix fair to coil and macromolecular material coil rack inner headed face, as motor iron-less core coil stator with resin.In same motor, when each phase coil only has one, can not have interval between each coil, only need the total number of coil to become the ratio of 3 to 4 with N face, the S face total number of magnetic surface, in motor, the coil of each same phase, same to voltage, electric current can be connected or use in parallel.Rotor installs at motor shaft the mild steel magnet skeleton connect with axle, be used for making rotor yoke magnet magnetic circuit, mild steel strong magnet skeleton periphery evenly processes the groove that many specific distribution coordinate with iron-less core coil stator, groove is embedded in the long rectangular magnet or magnet exciting coil that adapt, air gap between rotor and iron-less core coil stator, at 1 to 1.5 millimeter, mild steel magnet skeleton uses end carbon steel or cast steel to process, and also can be formed by stacking with low carbon steel plate punching press.Transmission connection between rotor and stator is by the bearing that the end cap at motor housing two ends and end cap connect with rotor axis of electric, bearing box forms, and at armature spindle, corresponding heat abstractor is installed, rotor specific distribution is, the long rectangular magnet or magnet exciting coil that adapt is embedded at mild steel magnet skeleton groove, and by magnetic field N face, S face is alternately distributed, N face, interval between face, magnetic field, S face is the same with the width in face, magnetic field, the intensity in magnetic field, face, magnetic field, shape, magnetic pole consumption is how many, by motor length, power, progression, the factors such as diameter determine, the corresponding increase collector ring when selecting excitation mode, the facilities such as carbon brush.
The invention has the beneficial effects as follows, outside each generator or motor efficiency increase, in order to improve its reliability in large and middle size motor, by the mode of excitation without magnet, can the more important thing is, the three-phase alternating current that generator sends and the three-phase alternating current that motor uses, frequency modulation device that need not be expensive, this creates more favourable condition to promoting the use of of iron-core less motor, and can with lower cost, cost of use, replace conventional motors completely, particularly big-and-middle-sized above motor.
