The motor/impeller assembly is the heaviest component of the whole HF DC set. The mounting bracket attached to the motor does two things that I can see:

—Carries the weight of the motor. The impeller shroud is supported by its own bracket. I don’t have an exact weight, but when I mounted mine, the motor was probably in excess of 40 pounds.

—The mount also absorbs the torque generated when the motor spins up. Without the motor being braced somehow, there will be significant twisting force between the motor and the impeller shroud.

Here’s a pic of mine mounted on a roll-around stand; it shows both mounting brackets, one fo rhe motor, one for the impeller shroud:

Bottom line: I think the motor mounting bracket is essential.
