Motor optimization for drive packages

The integration of drive components is becoming increasingly desirable in global industrial applications. End-users want the ability to control the speed of their drive train while ensuring their drive components operate at a high level of reliability and safety. When an electric motor and a variable frequency drive are designed to operate harmoniously, there is an opportunity to optimize cost and reliability of a drive train package. This paper provides examples of the improvements in drive train component size and cost when motors and drives are sized together as one package, verses having them sized separately without consideration of eachother. Also provided are examples of how cost of ownership due to efficiency improvements can be enhanced when taking into account the entire drive train package. Lastly, the application considerations required to ensure drive train reliability over the life of the installation are discussed.
