Linear Shaft Motor Sizing

One of the most straightforward tasks in the design of a linear motion system is to specify a motor and drive combination that can provide the force, speed and acceleration that is required by the mechanical design.

This is all too often the most overlooked aspect of the linear motion system design. Often, the engineer will select a motor, and then design a system around it. This approach leads to improperly sized motors for the application, making this the most costly aspect of the system, not only from the perspective of the initial purchase cost, but also due to service maintenance and energy costs.
