[QUOTE="Hugocz, post: 1139024, member: 415382"] I ran tests on the EGIS engine. The minimum PWM cycle is dependent on the PWM frequency. The minimum frequency of 10 Hz is practically unusable. The engine was no longer running smoothly. The table shows the PWM frequency [ Hz ] / minimum PWM cycle when the EGIS was still moving [ % ]. 10/10 50/10 100/15 200/15 300/17 500/20 PWM = 50Hz seems to be the optimal value for minimum smooth motor operation. EGIS was without mechanical load. The question is whether it would be appropriate to increase the PWM frequency at larger alternating values. [/QUOTE]
