The Motor need some 24Amps to run and triple of it to start. With a small motor maybe half as strong, you can make this.
I agree. I haverun several 3ph motors in Delta using caps with a timer switched extra "starter" cap. the system works well for motors up to about 3HP, above that and you will notice the lights dim on start up, and that will be the same with any neighbours connected to the same phase. G.
