What is the advantage to rotary phase converters vs VFD's? Obviously, I'm missing something.

Rotary converters are much cheaper in the larger sizes. The VFD is smaller , close to the same price in small sizes, and let you vary the motor speed.

#1 advantage is you can run multiple devices off one (1) rotory
converter.

#1 DISadvantage of VFDs is you can only run one (1) device off a vfd.

"The socialist movement takes great pains to circulate frequently new labels for its ideally constructed state.
Each worn-out label is replaced by another which raises hopes of an ultimate solution of the insoluble basic
problem of Socialism, until it becomes obvious that nothing has been changed but the name.
The most recent slogan is "State Capitalism."[Fascism] It is not commonly realized that this covers nothing more
than what used to be called Planned Economy and State Socialism, and that State Capitalism, Planned Economy,
and State Socialism diverge only in non-essentials from the "classic" ideal of egalitarian Socialism. - Ludwig von Mises (1922)
