The Torque-Speed curve for two representative ThinGap Embedded Motors is shown to the right.

Note how the torque actually increases at higher rpm, due to the increased cooling caused by both the inner and outer irons/magnets rotation and circulating air.

Current and torque are linear until the temperature limit is reached, since ThinGap Embedded Motors do not magnetically saturate. At the temperature limit, the magnets will demagnetize (typically about 120^c) or the copper in the coil will fuse.

A thermistor is embedded in the base of each coil for temperature monitoring, but the output should be considered relative rather than absolute due to conduction through the length of the coil.

Increasing torque with increasing rpm and no magnetic saturation provides a large amount of power for a given weight and package size. 

ThinGap Embedded Motors are not well-suited to low-speed or "traction" applications, since at 0 rpm there is no air circulating around the coil. The Motors depend on convection cooling from the air circulating around the motor, as opposed to more traditional iron-core motors which use conduction to transfer heat from the copper to the iron core.

Active cooling of a ThinGap Embedded Motor increases available torque dramatically for the same reason - the motor will not saturate. Active cooling is facilitated through the open-frame construction, and simple ducting of a fresh-air supply, which can increase the allowable current (hence torque) significantly. ThinGap will be running quantitative experiments with Active cooling in the future.
