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 so I thought) the wires (speed 1 - 4) all ran current at different levels to control the speed of the motor, then COM would be neutral. So would that mean E was ground?

Probably, yes: COM usually stands for common, meaning neutral. E usually stands for Earth, meaning ground.

I was assuming this was an HVAC blower, but this is actually a remote blower module for a range hood.

Installation instructions located here: Zline T95 Dual Remote Blower

The unit appears to be powered remotely from the range hood, where the control board and buttons are. It also appears to supply the cable. In this case, I would definitely assume E means protective earth in the diagram.
