Abstract

A permanent magnet power device is characterized in that a stator is provided with a stator magnet yoke / stator body, a permanent magnet assembly with an adjustable magnetic pole polarity, a matched magnetic shoe, a permanent magnet rotation driving assembly and a driving controller thereof, wherein the driving controller controls the permanent magnet rotation driving assembly to enable a N-S pole of each permanent magnet group to rotate or change a direction orderly or according to a set rule to construct at least one group of permanent magnetic dipole pair; and a permanent magnet rotation magnetic field or an alternating permanent magnet rotation magnetic field rotating in a counter clockwise or clockwise mode is formed in a coupling air gap between the stator and a rotor so as to drive the rotate to output torque. Defects that each engine or each internal combustion engine has large power consumption, a high-voltage large-power engine is difficult in speed regulation at present can be overcome, and power can be provided for each load device.

Description

Technical field [0001] The technical fields involved in the present invention include: power equipment technical field, energy technical field, especially a method for constructing a permanent magnet rotating magnetic field and a permanent magnet power device. Background technique [0002] In the familiar industrial and agricultural production and daily life of various equipment, there are countless examples of using electric motors or internal combustion engines as power drives. The equipment that can output power is the foundation of various human lives. Various electric motors or internal combustion engines within the scope consume most of the total current energy production capacity in the world, but with the massive consumption and gradual exhaustion of petrochemical energy, the increasingly serious environmental pollution, energy saving, emission reduction and environmental protection pressure and urgency Sense has risen to an unprecedented height, and there is an urgent ne...
