RPM, Votage, Current or Time Delay Relays for capicitor start circuit

| I am looking to finalize my rotary phase converter and am trying to
size up the disconnect relay for the capacitor start. My idler runs
about 18 amps with no load. It is a 15 hp 37 amp motor.
How do I size these relays? Do I need some special equipment for the
speed sensing relay?
