Its interesting to see a mimicking of coil duty cycles in rotarys now, coupled with interchangeable motors of varying speed and torque, coupled still with adjustable stroke lenthgs. Kinda makes you realize just how incredibly efficient coil machines really are because we are doing everything we can to mimic the stroke lenghts, duty cycles, speed and force of the coil based machines. Not sure if the stigma amen is gonna hit it out of the park but they have introduced another possible key factor to the rotary market.
