Perhaps the most important lesson from this particular project was just how much can be done with sensorless motors. We would be lying if we said that the startup phase of operation was not something which caused us a headache during development, especially at the lower temperatures, but the resulting performance proved that it can be done.
The sense of satisfaction from designing a controller to such tight specifications is especially rewarding and seeing the final product pass all of it’s extensive tests was something we were especially pleased about.
