- VFDs and rotary phase converters are two ways to power machines. VFDs are efficient for powering individual machines, while rotary phase converters are ideal for powering multiple pieces of equipment1. VFDs have better 3 phase control, variable speed, and soft start, but can only be used on one motor2. Rotary phase converters can run more than one motor, but need to be dialed in and sometimes need an idler motor and no soft start2.Learn more:✕This summary was generated using AI based on multiple online sources.

The right answer for you depends on several considerations. So let’s take a closer look at these choices, their advantages and disadvantages, and explore situations when one or the other makes more sense.www.americanrotary.com/blog/rotary-phase-conver…
Both ways work, under 5 hp vfd is cheaper over rpc is cheaper, vfd has better 3 phase control and veri speed and soft start, only can be used on one motor, rpc will run more than one motor, but needs to be dialed in, and sometimes needs a idler motor and no soft start...Phil
