AC Motors Part 5: AC Motor Life
One of the major impacts on motor life is common sense—or maybe the lack thereof!It always amazes me how many open drip proof (ODP) motors are used in agricultural irrigation applications where...
AC Motors Part Two-Three Phase Operation
Although a number of AC motor designs are used, the induction motor is, by far, the most common and will be the topic of this column. We will also focus on the three-phase design as it provides a more...
