Halbach Array Motor Pole Dimension Optimization

The patent applies parameter changes by optimizing the dimensional ratios of the field system components. Specifically, it defines α = w/τ (first dimension/third dimension) and γ = h/τ (second dimension/third dimension) as key parameters, where w, h, and τ represent the dimensions of the main pole and sub-pole. By establishing optimal ranges for these parameters (α ≥ γ and α = k/(γ-γ0) + α0), the design can adapt to various dimension and thrust requirements while maintaining a relatively simple Halbach array structure.

The patent optimizes the dimensional parameters w, h, and τ of the main pole and sub-pole to achieve optimal flux content. By defining specific parameter relationships (α = w/τ, γ = h/τ, and α = k/(γ-γ0) + α0), the design maximizes thrust generation while minimizing the weight of the field system. This parametric optimization allows the motor to achieve high thrust without proportionally increasing the field system weight.

The patent modifies the Halbach array structure by optimizing the dimensional parameters within established mathematical relationships rather than fundamentally changing the structure. The parameters α and γ are constrained by specific formulas (α ≥ γ and α = k/(γ-γ0) + α0), which provide clear manufacturing guidelines while achieving improved thrust characteristics. This approach maintains manufacturing simplicity through standardized parameter relationships.
