Embodiment Construction

[0079] The brushless motor of the present invention has an armature member containing several magnetically isolated electromagnet components to interact with a field magnet member containing several magnetic components, so as to obtain concentration of magnetic flux and even utilization of force, and by increasing The pole surface area of ​​the field magnet members and corresponding armature members across several air gaps facilitates a more even utilization of forces, eg Maslov et al. US Patent Grant No. 6891306 and related applications mentioned above.

Abstract

A multiphase brushless motor utilizes a multiphase arrangement of armature members in a brushless motor to correlate magnet polar fronts of magnet members with corresponding magnet polar fronts of armature members to achieve mutual deflection and reduce adverse impact of a breakdown torque on an output torque. In addition, with the help of one or more brushless motors, more parallel air gaps are increased in a multiphase brushless motor in a three-dimensional space, thus providing a higher torque output through a multiphase cluster under a condition of limited moving direction. Or more individuals connected in series and moving independently are arranged.

Description

technical field [0001] The invention relates to a motor structure, in particular to a multi-phase brushless motor. Background technique [0002] As far as general rotating electrical machines are concerned, regardless of the operation of DC motors or AC motors, the magnetic principle of like-sex repulsion and opposite-sex attraction is adopted between the rotor and the stator. For linear motors that produce a linear force, the stator and rotor of a rotary motor are replaced with those of a linear motor, but the principle of operation is the same. [0003] Kawai et al. proposed a power generating device in US Patent Grant No. 5,436,518, in which each magnetic circuit of several electromagnets of the stator is arranged to be independent of each other. Because the electromagnets are arranged to have their respective magnetic circuits independent of each other, they are magnetized independently of other electromagnets, and the electromagnets are sequentially excited to control ...
