You’d of been better off getting a two speed motor. Halving the motors speed may not force enough air over the motor to cool it.
If you know where I can get a 3hp two speed motor for less than the price of a motor and vfd then (£180) then I'm all ears, especially considering that's how Harrison did it. (Does your 140 have a two speed like John's?)
I like the idea of infinite speed control too as well as other features a vfd can offer.
I'm not overly concerned about cooling, there are ways and means of rectifying that.
