制造价格相对低廉换向器的共同方法,就是先做成金属筒壳,再用绝缘材料填充其间模塑成型。然后把该壳分成许多与轴线平行又彼此分割灼换向片,这些换向片就形成了最终换向器的换向片。换向器装于电机转子上的轴孔也常用模塑材料压塑而成。通常,筒壳在模塑和被分割成换向片前,为把而后被此分割的换向片与模塑绝缘材料固紧,成形的简 The commonest method of making the commutator at a relatively low price is to make a metal cylinder case first and then fill it with insulating material during the molding. The shell is then divided into a number of segments that are parallel to the axis and separated from one another and form the commutator segment of the final commutator. Commutator mounted on the rotor shaft of the rotor is also commonly used molding materials from compression molding. In general, the shell is molded and segmented into commutating segments, which are then clamped to a mold insulating material for the commutation segments which are then divided
