Another quick point on motors...........the PCM (digital controlled) motors are much better on energy usage than the analog controlled motors.

If the motor has 5 unique settings instead of a variable speed control it is more than likely analog.

PCM sends pulses of energy where analog uses the same energy for setting 1 or setting 5......but for setting 1, it bleeds the excess off as heat........NOT completely true, but it wastes quite a bit of energy.
