In both rotary or linear motor designs, heat dissipation limits performance. But cooling linear motors is much more challenging without the large surface area, and finned cylindrical metal housing of rotary designs.
Trilogy's linear motors use a combination of very high motor efficiency; heavy duty, high temperature magnet wire; and good thermal conduction from the winding to the aluminum attachment bar to reject heat.
During fabrication, the windings are formed into a planar surface to maximize heat transfer between the winding and the aluminum attachment bar. Once heat is transferred internally from the windings to the motor's coil attachment bar, it is rejected through (typically) a carriage assembly.

Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
