Product details
Part 122341-07 is an Ametek Lamb single-stage motor on the 5.7-inch frame, wired for 120 volts and built as a thru-flow unit from Lamb's AirWatt Series. Ametek lists its input power at 1275 watts and its replacement brush kit as 833326-51.
Single-stage motors move more air volume than a two- or three-stage motor of the same diameter, at the cost of somewhat less lifting power, which suits machines built around airflow rather than deep-pile suction. Thru-flow means the dirty airstream passes across the windings to cool them, the arrangement used in uprights and canisters rather than in central vacuum power units, which take a sealed bypass motor instead. Ametek rates this thru-flow family at sealed vacuums up to 142 inches of water lift and flow rates up to 146 CFM, and classes the motor in its standard flow group.
Because it runs one fan stage instead of stacking two or three, a single-stage motor puts less load on its bearings per hour of use, but the carbon brushes still wear on the same schedule as any Lamb motor. Watch for sparking visible at the housing vents, a motor that runs but delivers noticeably less airflow than it used to, or a burnt smell after extended running, any of which point to worn brushes rather than a failed motor.
Confirm the frame diameter, stage count and voltage stamped on your existing motor against this listing before ordering, since Lamb built several 5.7-inch single-stage motors with different mounting arrangements and lead lengths that are not interchangeable. Wiring should be handled by a qualified technician.
