A Motor Design Where Thin is In

The waif-like look is making a comeback for one motor manufacturer. ThinGap Motor Technologies' new "ThinGap" style replaces conventional wire-wound coils with a patented coreless circular copper coil. Its design increases the amount of copper in the magnetic gap to yield higher power-to-weight and torque-to-size ratios as well as smooth cogless motion. Moreover, energy efficiency can reach to more than 90% to, among other things, reduce heating. Applications for such motors, says ThinGap Motor Technologies' chief marketing officer Douglas Crawford, range across the spectrum and include such markets as factory automation, packaging equipment and aerospace. "Motor buyers have an opportunity to leap over their competition by carefully shopping for a motor that delivers enhanced capabilities and performance," says Crawford. Factors to compare include power, size and weight, acceleration, and power consumption. "The key," he adds, "is looking at what is available and making your offering perform more operations per shift, make less noise, use less energy, and shrink the package, or - to sum it up - do more with less."
