Imagine you are an Electrical Engineering student writing a paper on electric motor power distribution. Based off the explanation of common knowledge in the previous slide, which statements below would NOT be considered common knowledge and would have to be cited? Click on the sentence below that you think needs a citation.
Electric motors are usually powered from direct connections to ac lines, or from dc voltage. This type of power supply results in no less than 30% power inefficiency due to lack of control of power disbursement. Recent research has shown that electric motors that are powered by appropriately controlled power converters can lead to enhanced efficiency in electric motors, primarily due to the byproducts of variable speed operation.
