Re: Speed Controller Design
Ether,
When the locked anti-phase duty cycle is 50% current is flowing 100% of the time. 50% in one direction, 50% in the other, correct? An averaging meter will read this as zero while a true reading RMS will not.
During a previous discussion (2009) someone measured a CIM motor at .12 mH and 90 mOhm. At 150Hz this is very low but at 15kHz it is significant.
