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 drivetrain while ensuring that 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 drivetrain package. This paper provides examples of the improvements in drivetrain component size and cost when motors and drives are sized together as one package, as opposed to having them sized separately without consideration of each other. This paper also provides examples of how cost of ownership due to efficiency improvements can be enhanced when taking into account the entire drivetrain package. Finally, the application considerations required to ensure drivetrain reliability over the life of the installation are discussed.
