8 Performance Comparison

This section explains the test setup used for each of the technologies (magnetic and optical), as well as the resulting data to provide a suitable comparison of performance. For all tests explained in the following sections, the same motor listed in the key specifications is used.

Another set of tests for these two technologies, which could be crucial for product designers, is the performance comparison in dusty environments. In the case of encoders, it is imperative that devices are able to accurately detect the speed accurately, because these devices are expected to perform in dirty environments in some cases. If the technology cannot perform well in these conditions it could cause unwanted system behavior resulting in poor system performance.
