I would use an ebike controller such as from bmsbattery , above simple controller works but not efficient, also neomagnets have to be used, hopeless with ceramic magnets, its good educational tool how to run 3 phase fp motor but for ev project you really need to use 12fet or higher ebike controller

His 12 Fet controller is a very good controller. I have used it on a geared BMC, X5, and 9C. People even use it on Cyclone motors.
The good thing about the Lyen controller, as you point out, is that you can get it so your Cycle Analyst (Direct plugin) plugs straight in. You can also get Lyen to fit it with a programming cable so you can program it. His response time, packaging, and service is top shelf.
