换向器、使用该换向器的电机及换向器的制备方法
摘要：
本发明涉及一种换向器，包括绝缘基座及设于所述绝缘基座上的若干换向片，其中每一换向片包括依序设置于基座上的金属层、过渡层及碳层，所述过渡层含有与碳层相同的材料及与金属层相同的材料，同时本发明还涉及一种包括上述换向器的电机以及该换向器的制备方法，本发明提供的换向器由于过渡层含有与碳层及金属层相同的材料，解决了在高温烧结时炭层与金属层开裂的问题；延长了该换向器的使用寿命，且本发明提供的换向器的制备方法减少了传统技术中使用的电镀与钎焊所带来的化学污染与制作成本。
摘要（英）：

The invention relates to a commutator which comprises an insulating base and a plurality of commutator segments which are arranged on the insulating base, wherein each commutator segment comprises a metal layer, a transition layer and a carbon layer which are successively arranged on the base. The transition layer comprises a material which is same with the carbon layer, and a material which is same with the metal layer. Furthermore the invention relates to a motor with the commutator, and a preparing method of the commutator. According to the commutator provided by the invention, because the transition layer comprises the material which is same with the carbon layer and the material that is same with the metal layer, a cracking problem of the carbon layer and the metal layer in high-temperature sintering is settled, and service life of the commutator is prolonged. Furthermore the preparing method of the commutator according to the invention reduces chemical pollution and manufacture cost caused by electroplating and soldering in traditional technology.
