The Ametek Lamb 117507-13 is the 120-volt three-stage 7.2-inch bypass motor that carpet cleaners know best, because it is the vacuum motor used in dual-vac portable extractors such as the Ninja Deluxe Dual V. Three stages give it the sealed lift to keep pulling water back up fifty feet of hose, and at 21,425 RPM with a 12.7-amp ceiling it stays inside a standard 120-volt circuit. When a truck-mounted crew retires a portable, this is usually the part that brings it back.
Use cases

- Replacing a burned-out vacuum motor in a dual-vacuum extraction machine.
- Central vacuum power units specified for the 117507-13 build.
- Commercial canister and utility vacuums that need lift more than raw airflow.

Choosing and fitting
On a two-motor extractor, replace vacuum motors in pairs where you can. A new motor working beside a tired one does more than its share and wears faster, and the machine never quite gets back to the recovery it had. Match the exact dash suffix on the casting, confirm the 7.2-inch diameter and bolt pattern, and fit new mounting gaskets. Keep the recovery tank's float shutoff working: water reaching a vacuum motor ends the repair immediately.
Frequently asked questions
Which machines use the 117507-13?
It is the three-stage vacuum motor used in dual-vac portable extractors including the Ninja Deluxe Dual V, and in various central vacuum and commercial canister units. Confirm against your machine's parts list or the number stamped on the motor before ordering.
Should I replace both vacuum motors at once?
On a dual-vacuum extractor it is usually worth it. Motors age together, and a fresh motor paired with a worn one carries more of the load and wears out sooner. If budget forces one at a time, plan for the second within the same season.
Does it have a thermostat?
Yes, this build includes a thermostat along with an air seal for the bearing area. That does not remove the need for the machine's own overload protection or for keeping filters and the float shutoff in good order.
Why did my old motor fail so quickly?
The two most common causes on extraction machines are water reaching the motor through a failed float shutoff, and brushes worn past their limit chewing up the commutator. Both are preventable with routine checks and a spare brush set on the shelf.
