Electric Motor Controls are an increasingly important part of our industrial infrastructure. Recent advances in semiconductors and computation give compelling cost economies with electronic motor controls.
This talk will focus on industrial motor control technology, with emphasis on the synergistic effects of computers and power semiconductors. Eric will discuss both the history of power switching devices and its interaction with computing and economics. DC and AC drives will be contrasted, and the Drop-Proof DC hoist circuit will be shown.
