Product details
This Ametek Lamb motor, part 122264-07, is a 5.7-inch, 120-volt, two-stage unit from Lamb's Advantek thru-flow line, rated at 698 peak air watts. Ametek lists its input power at 1550 watts and its replacement brush kit as 8505936-50.
Thru-flow construction means the air the machine picks up passes across the motor windings on its way out, which is the arrangement used in uprights and canisters rather than in central vacuum power units, where a sealed bypass motor is used instead. Ametek describes the Advantek design as needing less input power for the same air performance, and rates the Advantek thru-flow family at sealed vacuums up to 136 inches of water lift and flow rates up to 135 CFM.
Because the cooling path depends on air actually moving through the motor, a full bag, a clogged filter or a pinched hose leaves this motor running hotter than it should on every use, not merely cutting suction at the floor. Two-stage construction pulls air through two fan wheels in sequence rather than one, which is how Lamb gets more lift out of the compact 5.7-inch frame than a single-stage motor of the same size produces.
Motors wear slowly rather than failing outright. Suction thins out, the unit runs louder over time, and carbon brush wear eventually shows up as sparking or intermittent power before the motor quits for good. Hold your old motor next to this one and check that the frame diameter, mounting and lead arrangement line up before you order, and leave wiring work to a qualified technician.
