摘要： An outer rotor type hybrid stepping motor includes a stator, a rotor, a magnet disposed axially in the stator or the rotor, a stator core disposed inwardly from a gap between the stator and rotor, and a stator winding on the stator core. The rotor is disposed outside the gap. The magnet has an axial cross sectional area A. The residual magnetic flux density of the magnet is Br, and a total of magnetic fluxes exiting axially from the surface is A×Br. A gap average magnetic flux density, determined by dividing A×Br by the top cross sectional area small teeth poles on the rotor is Bg; pitch of the teeth is τ; and tooth width is Tw. Average magnetic flux density Bg, tooth pitch τ, and tooth width Tw are determined by the equation K=1/(π×Bg×Tw/τ), with the coefficient k in a range of 0.56-0.66 (1/T).

摘要： In an outer rotor type hybrid stepping motor, when assuming that a teeth pitch is τ and a tooth width is Tw (tooth width ratio is Tw/τ) and in case of Tw/τ=0.3, the maximum torque can be obtained when a gap average magnetic flux density Bg is 1.6-1.8T, which is determined by dividing a total magnetic flux amount calculated from residual magnetic flux density Br of a magnet and surface area A of the magnet with small teeth surface area At of a rotor. Since the small teeth surface area At can be expressed by a product of the small tooth width Tw, number of small teeth Nr and a lamination thickness L, an optimum lamination thickness can be determined with only one solution. Further, in case of different teeth width ratios, the following gap magnetic flux densities Bg assume optimum values, in that when Tw/τ=0.35, 1.4-1.5T, when Tw/τ=0.4, 1.2-1.4T, when Tw/τ=0.45, 1.0-1.2T are set. When assuming that a cross sectional area in the axial direction of the magnet is A, a gap portion diameter is D, the lamination thickness of the stator core in the axial direction is L and a residual magnetic flux density of the magnet is Br, the lamination thickness in the axial direction L and the residual magnetic flux density Br is determined according to the following equation under a condition that a coefficient k in the following equation is kept in a range of 0.56-0.66(1/T) D×L/A=k×Br [k=1/(π×Bg×Tw/τ)]. Whereby, an outer rotor type hybrid stepping motor which uses new indexes for optimum design parameters of the motor and which realizes size reduction, a high output and a high resolution is provided.
摘要翻译：在外转子型混合式步进电动机中，当假设齿距为τ，齿宽为Tw（齿宽比为Tw / tau）时，在Tw /τ= 0.3的情况下，当a 间隙平均磁通密度Bg为1.6-1.8T，其通过将由磁体的残留磁通密度Br计算出的总磁通量除以磁体的表面积A与转子的小齿表面积At来确定。由于小齿表面积At可以由小齿宽Tw，小齿数Nr和层叠厚度L的乘积表示，所以可以仅用一个解决方案来确定最佳层压厚度。此外，在不同齿宽比的情况下，以下间隙磁通密度Bg呈现最佳值，因为当Tw /τ= 0.35,1.4-1.5T时，当Tw /τ= 0.4,1.2-1.4T时，当Tw / tau = 0.45,1.0-1.2T。当假设磁体轴向的横截面积为A时，间隙部分直径为D，定子芯在轴向上的层压厚度为L，磁体的剩余磁通密度为Br，在以下等式中的系数k保持在0.56-0.66（1 / T）的范围内的条件下，根据下式确定轴向方向L和剩余磁通密度Br的层叠厚度DxL / A = kxBr [k = 1 /（pixBgxTw / tau）]。由此，提供了一种外转子型混合式步进电动机，其使用新的指标来实现电动机的最佳设计参数，并实现了尺寸减小，高输出和高分辨率。

摘要： An outer rotor type hybrid stepping motor including a stator, a rotor, a magnet disposed axially in either the stator or rotor, a stator core disposed inward from a gap formed between the stator and rotor, the rotor disposed outside the gap, and a stator winding wound around the stator core. The outer rotor type hybrid stepping motor has a cross-sectional area A in the axial direction of the magnet, a gap portion diameter D, a lamination thickness of the stator core in the axial direction L and a residual magnetic flux density of the magnet Br. The lamination thickness of the stator core in the axial direction L and the residual magnetic flux density Br are determined according to the equation D×L/A=k×Br with the condition that coefficient k is kept in a range of 0.56-0.66(1/T). The resulting optimized design parameters for L and Br provide a reduction in size of the outer rotor type hybrid stepping motor, a high output and a high resolution.
