Product details
This is Ametek Lamb part 115334, a 7.2-inch, two-stage bypass motor wound for 120 volts and fitted with a tangential discharge horn.
The horn on a Lamb motor is the discharge duct rather than an alarm fitting: it is shaped to guide pressurized exhaust air out of the motor and into the power unit housing the way the machine was designed to vent. Ametek builds this one on its older-style 7.2-inch platform, classes it as a high performance motor, lists its input power at 1375 watts, gives its replacement brush kit as 833415-54, and rates the 7.2-inch bypass tangential family at sealed vacuums up to 135 inches of water lift and flow rates up to 125 CFM.
The bypass arrangement keeps cooling air for the motor separate from the dirty airstream the system is pulling in, which is standard for central vacuum power units of this frame size. Wear shows up as a bearing note that shifts from a smooth hum to a grind or whine, suction that fades across the system even with a clear hose and empty canister, running that cuts out under load, or a burning smell.
Its sibling part 115330 is the same frame and voltage with a peripheral discharge in place of the horn, so confirm which discharge style your power unit is built around before ordering. This part carries mains voltage, so disconnect power at the unit before opening it up, or leave the swap to a technician if you are not confident with the wiring.
