In doing so it tripped the sheds fuse. The motor smelt like burning rubber. After letting it cool, I tried turning it back on under no load and it only turned slowly, and then clicked and shut off.

I am just wondering if anyone knows what the issue could be?

Thanks in advance.

It sounds like the motor has overheated and cooked off some wiring insulation and will need to be rewired or replaced. Modern motors will have a heat sensor that trips out before a motor gets too hot and does what yours di.
