SELECTING STEP MOTORS VS. SERVOMOTORS

摘要

This paper has outlined the procedure used to select the optimum motor, the power transmission device (when required) and the motion profiles necessary to perform the application's desired motion objectives. Guidelines and rules of thumb outlined the basic advantages and limitations of the key motor lypes.rnThe procedure is one that requires a basic understanding of how an electric motor works in a motion control system. Although the step motor has its own unique performance characteristics, it is governed by the same laws of physics and motion selection that govern the selection of brush dc and brushless dc motors. The major consideration for the application's engineer is often to select the lowest cost motor and power transmission need to perform the desired motion and achieve the customer's operating objectives.
