1. the permanent rotary magnetic-field construction method of a controlled magnetic circuit permanent magnet power device, it is characterized in that, controlled magnetic circuit permanent magnet power device is made up of controlled magnetic circuit permanent-magnet stator and rotor and other suitable annex, controlled magnetic circuit permanent-magnet stator body is laid the controlled magnetic circuit permanent-magnet component of at least one pair, controllable permanent magnetic closed loop bypass magnetic circuit and controllable permanent magnetic couples magnetic flux path is provided with in the controlled magnetic circuit permanent-magnet component of every pair, controllable permanent magnetic couples magnetic flux path and rotor are air-gap field coupled structure, with timesharing clockwise or counterclockwise, circulation or the controlled magnetic circuit permanent-magnet component of programming Control in permanent magnetism closed loop bypass magnetic circuit "ON"/"Off" or permanent magnet coupling magnetic circuit "ON"/"Off", controlled magnetic circuit permanent-magnet component is by permanent magnet, magnetic boots and permanent magnetic circuit by-pass switch thereof are formed, permanent magnetic circuit by-pass switch is made up of bypass iron core driven unit and bypass iron core, bypass iron core driven unit is made up of servo drive and driving shaft, bypass iron core is installed on the driving shaft, permanent magnet in controlled magnetic circuit permanent-magnet component is arranged between two magnetic boots or is arranged between magnetic boots and yoke, one end of magnetic boots is permanent magnetism bypass end, the permanent magnetism bypass end of two magnetic boots and bypass iron core form controllable permanent magnetic bypass magnetic circuit, the other end of magnetic boots is provided with the magnetic boots coupling surface for setting up " controlled magnetic circuit permanent-magnet stator---rotor " air gap Coupled Magnetic Path, at controlled magnetic circuit permanent-magnet stator and the permanent rotary magnetic-field being formed in the air gap that is coupled between rotor counterclockwise/turn clockwise or alternation permanent rotary magnetic-field, controlled magnetic circuit permanent-magnet stator and rotor have four kinds of rotary magnetic torque structures, first permanent rotary magnetic-field or alternation permanent rotary magnetic-field respectively with radial magnetic field cartridge type squirrel-cage armature rotor, radial magnetic field cartridge type wound armature rotor, axial magnetic field dish-type pot grate formula armature rotor, axial magnetic field dish-type wound armature rotor, oblique magnetic field cone cartridge type mouse cage/pot grate formula armature rotor or the suitable structure of oblique magnetic field cone cartridge type wound armature rotor form the rotary magnetic torque structure of " stator permanent magnet rotating magnetic field---rotor inductive currents coupled magnetic field ", its two be permanent rotary magnetic-field or alternation permanent rotary magnetic-field respectively with radial magnetic field barrel-type permanent magnet formula rotor, axial magnetic field dish-type permanent magnet rotor and the suitable structure of oblique magnetic field cone barrel-type permanent magnet formula rotor form the rotary magnetic torque structure of " stator permanent magnet rotating magnetic field---rotor permanent magnet coupled magnetic field ", its three be permanent rotary magnetic-field or alternation permanent rotary magnetic-field respectively with radial magnetic field cartridge type metallic conductor formula armature rotor, axial magnetic field dish-type metallic conductor formula armature rotor or the suitable structure of oblique magnetic field tapered metallic conductor formula armature rotor form the rotary magnetic torque structure of " stator permanent magnet rotating magnetic field---rotor inductive loop coupled magnetic field ", its four be permanent rotary magnetic-field or alternation permanent rotary magnetic-field respectively with radial magnetic field cartridge type combined type armature rotor, axial magnetic field dish-type combined type armature rotor, the suitable structure of oblique magnetic field tapered combined type armature rotor forms the rotary magnetic torque structure of " stator permanent magnet rotating magnetic field---the compound coupled magnetic field of rotor ", the compound coupled magnetic field of rotor has two kinds of i.e. inductive loop and the compound coupled magnetic field of induced current, inductive loop and the compound coupled magnetic field of permanent magnetism, under the manufacturing process adopted at various parts and material equal conditions, increase the diameter of controlled magnetic circuit permanent-magnet stator and rotor or/and length, or increase the quantity of permanent magnet assembly of adjustable pole polarity, power output is increased and reduces energy consumption, rotary controlled magnetic circuit permanent magnet power device can be built on the one hand according to said method, be similar to structure of the linear motion actuator mode ground linear structure to above-mentioned controlled magnetic circuit permanent-magnet stator and rotor on the other hand to launch, controlled magnetic circuit rectilinear movement/alternation permanent magnetic field can be formed, and then build the controlled magnetic circuit permanent magnet power device of orthoscopic.
