Even better, a multiplicity of innovative control system approaches can be vetted quickly -- without expensive hardware tooling -- using a high-fidelity model that supports rapid testing over a full range of anticipated loads. This dramatically shortens development of controls that can predictably and accurately bridge the gap from system design to robust real-world performance.
In a real-world example, a control design integration project employing the methods noted above was completed in months, or about two years ahead of the initial timeframe targeted by the manufacturer. The methods discussed here will take on added importance in the race to market, not only in terms of overall product area leadership, but also (for some manufacturers) in terms of securing exclusive technological advantages.
We anticipate a surge in innovative applications involving proprietary technology and potentially patentable system components, whether they are owned by the manufacturer or licensed for a specified period from outside developers. The promise of sensorless BLDC motors with integrated controllers is just beginning to be realized. For motor and end-product manufacturers, advanced-level BLDC design will be the key to gaining the outcomes desired, functionally as well as financially. Finding and engaging the right talent, whether in-house or elsewhere, is a must.
