Yes I was holding off commenting, a 3 phase motor for a RPC can be rope started in place of a single phase pony motor. Once the 3 phase motor is started and running on single phase it generates the 3d phase itself.
As a electrician who worked on industrial for many years and then crossed over to HVAC/R I build my own phase convertor as I had access to lots of used Run caps and start caps and used a potential or voltage relay to start the motor and then drop out the start cap. Generally speaking to make a RPC it needs to be larger than the run load motor by at least 1/3.
