You are to create a thorough overview that fully explains the information found on a motor nameplate. This
explanation can be in the form Word document that
fully explains each of the variables listed below.
Download the motor specifications, performance data, and any
other information needed to answer the following from the Leeson website (www.leeson.com) or other motor
resources.
If you go over and above by collecting
additional information, embed charts or drawings, or give an insightful explanation your grade will increase.
Bonus points will be awarded for neatness, grammar, and the overall professional appearance of the
presentation.
