Product details
Part 116884-49 is an Ametek Lamb motor, a 5.7 inch, 2-stage through-flow design built for 120 volt use and mounted on ball bearings. Ametek publishes it with thermal protection and a 1025 watt power level.
A through-flow motor draws its cooling air across the motor windings on the way to the fan stages, rather than keeping the cooling air and the working air on separate paths the way a bypass motor does. The two fan stages work in series, each stage adding to the vacuum the motor produces beyond what a single-stage motor of the same size could reach. Ball bearings, rather than sleeve bearings, are why this design holds its rated performance longer under continuous use.
As a motor of this type wears, the most common signs are a gradual drop in suction, a rise in operating noise, or the unit running noticeably hotter than it used to. Because the motor is the part that generates suction rather than the bag or the hose, none of those symptoms improve with a bag change if the motor itself is the cause.
