That jogs a memory, I remember working at Oxford Observatory, used 100v? DC , we converted it to AC in order to hook up to the grid!
Back then I was an Electrician, moved on since then!
When I practiced in the UK from the 1950's it was 230v and gradually introduced 240v as standard.
I have been away from it for some decades.
(I/we used imperial wire size at that time e.g. 3/.029 etc)
Generaly start switches are used/needed on motors above 1 HP and usually have a start cap, as well as the run cap.
Often these smaller fan motors just have a continuos fed , phase shifted start winding.
But 1ph induction motors do not control well using speed control methods.
This is why those...
The common arrangement now is the waste-spark method of ignition, where each coil feeds two cylinders with the primaries being isolated from the secondary now.
The may be a form of this , but a pair in one unit.?
What is the type of relay?
You should use a motor-rated contactor for this application.
The other option is to set up a Safety Relay, they are more prevalent in Europe, but slowly N.A. is making them mandatory.
Are the cores Toroidal? This is what you need preferably, they are also the most efficient means of transformation so the turns/volt is not high at all,
Experiment with a couple of windings, Pri & sec and find the the turns ratio (turns/volt)
I recently put together an electric fence unit that uses a modern 'Waste-Spark' coil, IOW it has two HV plug connectors, with the fence unit, one is connected to the earth gnd connector,
BTW Condenser is an old term for what now is a Capacitor. Usually 0.1uF
But I see you are using the older...
