What do E and COM mean in a blower motor wiring diagram?

I'm a bit confused with the wiring diagram of this blower motor. Is the COM the neutral wire or the hot wire? And then would the E be neutral if the COM was the hot wire? Or is it the ground? I thought that since this was a variable speed motor (or…
