Single-phase to 3-phase AC motor conversion

[Sputnik]

We had this old electric lawnmower. I don't remember what went wrong with it, but it was given to me to destroy. I want to use it as a motor for a potential e-bike conversion, and figured three-phase would give me more power and speed control. So I decided I'd attempt to rewind this motor for 3-phase power since it would also prove to be an intriguing endeavour.

This is the 1800W single-phase AC motor from the lawnmower.

Here's the stator.

Here you can see there are 24 slots so it will be possible.

Currently all the windings have been removed and I'm on the look out for new copper. My options are quite limited . The original primary winding was 0.8mm and the auxiliary winding was 0.7mm. I'm thinking I should use 1mm diameter wire if I am to use a voltage lower than 220V to drive it. Any opinions?

Also, should I wind for four poles or eight poles? I know eight poles will be half the speed of four poles for a given drive frequency, but will it have more torque?

Thanks,
