Modern machine design is all about delivering higher performance at a lower cost with higher reliability. Delivering these often-conflicting performance characteristics is the mark of a great designer, and for the most common form of industrial motion, rotation, newer applications such as SCARA robots and their end effectors need torque with low mass in the smallest possible footprint. Frameless motors are an ideal choice for applications that are space-limited or must strictly control inertial mass. Kollmorgen frameless motor expert Tom Wood discusses the technology in conversation with Jim Anderton in this podcast.
