DC micro-motor is audio-visual equipment, office automation equipment, communications equipment and automotive manufacturing also indispensable devices. Where DC traction motor commutation is an important performance indicator, the normal operation of the motor has an important impact. Therefore, the DC motor commutator performance is the most important. And wherein the commutator commutation process is divided into steady-state and transient, it is not just a simple electromagnetic phenomena, but also affect the mechanical, electrochemical, ionization, etc., it is very complicated research. So the commutator motor called the most complex element too. Therefore, a reasonable choice of commutator structures, materials, and scientific design and rigorous implementation of the process, to ensure the motor manufacturing quality, safe operation and long service life, are of great significance. The impact of micro-motor commutator performance, depending on the process realized under certain conditions, the brush slides relative told circuit conducting, through comparative analysis of domestic and foreign micro-motor operating conditions, we can know the result commutator wear The most critical factor in the performance of change. So we had to commutator materials the following requirements. 1. The need for as little contact resistance. 2. better chemical stability, anti-oxidation and corrosion aspects to highlight. 3. Distribution brush material has to match the hardness. The extinguishing capacity, better thermal conductivity properties, temperature coefficient of resistance is small. |
