Although motors are a fundamental part of any motion system, selecting the right motor for an application is rarely an easy decision. There are various motor technologies to consider, and each has characteristics that can affect the design in different ways.
In recent years, engineers have come to realize that motion control can be smart. This type of control involves machines that can digitally interact with operators, track each step of the assembly process, ensure quick product changeover and provide the real-time status of available resources.
Successful manufacturers never get tired of facing new market challenges. This statement applies to companies across all industries—including those involved in the annual manufacturing of more than 1 billion tires worldwide.
The distinction between AC induction motors and permanent-magnet DC servomotors was once fairly clear. AC motors were for high-horsepower applications, such as compressors, pumps, blowers and bulk-handling conveyors. DC servomotors were for applications requiring low horsepower, high torque, high cycling and precise positioning, such as machine tools and pick-and-place machines.
When K.A. Swanstrom founded Penn Engineering & Manufacturing Corp. in 1942, he did so with a revolutionary new product: a self-clinching fastener that provides load-carrying threads in metal sheets too thin to be tapped.
In a competitive marketplace, details help differentiate one product from another. A thoughtful feature or a more rugged design can make all the difference. Consumers who buy based solely on price often end up disappointed.
"We’ve managed to pack quite a lot of power density in a small package." —David Ma, Yaskawa America

Semiconductor processing equipment is a notoriously demanding application for motion control engineers. Extreme precision, reliability and smoothness are absolute requirements. At the same time, space is at a premium.
Traditionally, a complex manufacturing machine has one large, powerful controller that governs sequencing, motion and I/O. Multiple drives and motors are connected to the controller via a motion network.
Designing and manufacturing high-bay warehouses is a specialty of SSI Schäfer, a German international logistics compa-ny. These warehouses feature welded steel beams that are used as horizontal load carriers in shelving systems.
