Get PriceSpeed range The idle speed (approx. 400,000 min-1) of turbines is an indicator of their cutting performance. The advantage of electric motors is that the speed and torque can be very easily controlled. The speed of brushless electric motors can be controlled within a range of approx. 100 to 40,000 min-1. These motors offer a stable torque throughout their entire speed range.
Get PriceThe air motor drives the bur indirectly via a contra-angle handpiece or straight handpiece. It reaches a maximum speed of 25,000 rpm. Contra-angle handpieces are available in various speed-increasing and speed-reducing ratios.
