I don't see any point in fitting large motors, motors that don't suit variable speed, motors that have far more power than is needed, motors that simply don't fit. Many of us have gone down the route of fitting a 24 V DC motor of 100 to 150 Watts, using
cheaply available 24 V power supplies and any of a wide range of speed controllers, all readily available on Ebay and other markets and easy to fit and use.
Why spend weeks debating what to do? We know what to do. It could have been all built and working in the time it's taken to get nowhere.
