The Instrumentation of Surface Uniformity Commutator Control Spindle Automatically

This research aims to 1) Create a commutator smooth surface measurement by using the laser displacement sensor. 2) Automatically correct and store data. 3) Develop a computer program for measuring the surface of commutator. The research methods are divided into two stages. First, design a commutator smooth surface measurement by using the laser displacement sensor and built base station in order to adjust position of the laser displacement sensor. Additionally, we create a set of motor-drive automation to stabilize the commutator speed by installing the encoder Incremental to obtain the position and angle. Second, we develop a computer program for measuring the commutator surface in real-time and compare our results of the smooth commutator surface in a polar form with commutator surface reference graphs. The results showed that, our commutator surface measuring set effectively measured the smooth surface and fault models. Moreover, our design program effectively displayed in linear graphs and polar graphs the damaged or worn surface of the commutator.
