they do not need a tensioner, you cent the motor shaft and output shaft's Center-to-center in such a way that the belt would allow the motor to "idle"
* i know this because we run a cvt style centrifigal clutch on my racecar*
centrigal force via ramps inside the primary clutch squeze the cones together, puting force onto the belt. At high rpm, then the cones are as close the belt gets tighter- this tension spreads the cones of the secondary unit, making the effective Pulley diameter of the primary larger then that of the secondary, creating overdrive.
Great concept but your would need to do extensive testing with different ramps, weights and springs to find a good mix
