Product details
The 116110 is an Ametek original, meaning it comes from Ametek's own Lamb motor line rather than a third-party equivalent, and it is sold here as part 205F for central vacuum power units originally fitted with this motor.
What Lamb publishes for it: two fan stages, a 5.7 inch bottom diameter, a 5 amp draw at 220-240 volts, 355 air watts, 103 CFM and 98 inches of sealed suction. Systems it went into include Modern Day, Flo-Master, Nutone, Central Vac International and Filtex, and it stands in for no other part number.
Labels reading 6110 or 11-6110 identify the same part. Match the number on your current motor exactly, since Lamb produced several similar-looking motors across its 116xxx range for different voltages and mounting styles.

A central vacuum motor is a wear item. As it ages, expect a breaker that trips more often, a burning or electrical smell, sparking visible near the top of the housing, or the unit shutting off and restarting on its own. Reduced suction across every inlet, not just one, usually points to the motor rather than the hose or attachment.
