Integration of Motors and Drives

Abstract

This paper examines the benefits of adopting a second-generation integrated motor and inverter. Removing the barriers to ensure that variable speed drives are more readily applied results in on-going cost savings to the user through energy savings plus process control benefits. In addition, the use of an integrated product instead of two separate components results in cost and time-savings to the installer. The simplification of integration, by transferring the guarantees of performance in efficiency, torque overload and stiffness, speed accuracy, noise and EMC compliance, allows optimization by the design team to be realized by users and ease of application since the primary design team guarantees the product performance. The introduction of second generation compact product assists user conversion from present inefficient mechanical solutions. This technology is currently applicable in power ratings below 22kw, which includes the vast majority of practical applications.
