Is it possible to drive a small synchronous motor with permanent magnetized rotor to other speeds it is designed for?
I tried to drive a small clockwork AC motor which is symmetrically build but mechanicaly constrained to one direction. I tried to drive it at different frequencys, while some lowers (eg. 20 Hz) seem to work to some point, the motor seem to stall at higher frequencys above 100 Hz it seems. Also I could not test at lower frequencys so far.
The voltage it needs to spin up rises with the frequency it seems. At 20 Hz, it works from 40 V, while it almost need the 220 V it's rated to spin up at 50 Hz.
Is it possible to spin it at 1/10 or 10 times of the design frequency if the voltage is adjusted, or is the frequency limited by design?
