Product details
This Ametek Lamb 5.7 inch motor is a single-stage, thru-flow suction motor rated for 120V operation. In a thru-flow design, the air the fan pulls in flows directly across the motor's windings before exhausting, using the working airstream itself to cool the motor rather than a separate cooling fan, which is why thru-flow motors are built only for dry pickup and should never be run in a wet-pickup application where moisture could reach the windings.
Ametek publishes this motor under part number 116309-00 as a 5.7 inch frame, single fan stage, 120 volt AC unit with thru-flow output at the 750 watt power level, in its Traditional Lamb motor type and standard flow class, and names 833400-63 as the replacement brush kit. Published performance figures for the motor give 190 air watts, 112 CFM of airflow and 63 inches of sealed suction. Ametek prints no machine-by-machine fitment list against it, so confirm your existing motor's diameter, stage count and voltage before ordering.
A motor that has reached the end of its service life typically shows reduced airflow even with clean filters and an empty bag, a burning smell, visible discoloration or scorching around the vent slots, or a grinding or rattling sound from worn bearings. Because this is a single-stage design, expect somewhat lower sealed suction than a comparable 2-stage motor of the same diameter, which is a normal tradeoff for the higher airflow single-stage motors typically deliver.
