A discussion on the future path of electrical variable speed drives used to be a straightforward matter. The direction for advancement was governed by the customer demand for lower cost and smaller products, and both the control and power domains were limited by advances in silicon. Today that discussion is far more complex, involving the perhaps surprising question: 'What is a drive?' A simple enough question you may think. But attempts at an answer quickly reveal that the world of electrical variable speed drives is as broad and diverse in range and application as the technologies it embraces.
