Spindle - Jena Tec

High Frequency Spindles use the rule that the speed of an AC Induction motor is proportional to the frequency of the electric supply. So, on a 2-pole motor, a 50Hz supply will give a synchronous speed of 3000 rpm and increasing the supply frequency to 100Hz will give a synchronous speed of 6000 rpm. The variation in frequency
