Product details
Lamb builds this two-stage motor at 5.7 inches across the fan housing specifically for 240-volt equipment, sold as part 116259-00. The voltage is worth checking before anything else: dropping it into a machine wired for 120 volts, or the reverse, will not deliver the pull the equipment was engineered around, even when the frame size and mounting line up perfectly.
Ametek catalogs it as a bypass tangential motor, lists it at 240 volts AC with an input power of 825 watts, gives its replacement brush kit as 833508-50, and rates the 5.7-inch bypass tangential family at sealed vacuums up to 220 inches of water lift and flow rates up to 107 CFM. A two-stage motor at this frame size is the usual pick where equipment needs to hold suction steady through hours of continuous running rather than deliver the highest possible airflow in short bursts, which puts it in central vacuum systems and commercial floor equipment more often than household uprights.
The failure pattern reads the same regardless of what it is installed in: suction that has faded and stays down after a filter change, a burning smell during use, a bearing note that has picked up a rumble or whine, or a unit that refuses to start. None of that narrows down the machine brand, since this frame and voltage combination was supplied to a range of equipment built around a motor this size.
Match the frame diameter and the voltage on the data plate, and confirm the stage count matches, before ordering. Because this carries 240 volts, cut power at the breaker rather than just unplugging the machine, and have a technician handle the swap if the wiring inside is unfamiliar.
