电机换向片尺寸精度直接影响换向器结构尺寸精度。它的厚度大小影响换向器直径,它的角度变化影响换向器紧固程度。故在生产中必须严格控制换向片尺寸精度。换向片是由冷拔梯形铜排制成。换向片的梯形铜排尺寸偏差及其测量方法在JB651-68部颁标准中已作了一些规定,但数据不全,特别是量具制造偏差根本未予提到。长期以来我厂参照梯排尺寸精度标准,并根据实际情况编制
Motor commutator size accuracy directly affects the commutator structure size accuracy. Its thickness affects the commutator diameter, and its angle changes affect the commutator’s tightness. Therefore, the production must be strictly controlled the commutator size accuracy. Commutator is made of cold drawn trapezoidal copper row. Commutator trapezoidal copper bar size deviation and measurement methods JB651-68 ministerial standards have made some provisions, but the data is not complete, especially measuring the manufacturing deviations are not mentioned at all. For a long time, our factory has referred to the dimension accuracy standard of ladder row and made it according to the actual situation
