Product details
This Ametek Lamb motor, part 117123-00, is a three-stage, 5.7-inch bypass unit built for 220/240-volt central vacuum power units, supplied with the discharge horn fitted. Three-stage construction on the smaller 5.7-inch frame trades some air volume for extra lifting power, which is why manufacturers reach for it on systems that need to pull hard through a long or narrow pipe run.
Ametek lists this motor at 240 volts AC with an input power of 1550 watts, gives its replacement brush kit as 833423-62, 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. The horn is the discharge duct rather than an alarm, offered by Ametek in either a diecast or a thermoset version to guide pressurized exhaust air out of the motor.
The 220/240-volt rating matters here: this motor is wound for the higher voltage used in some markets and installations, and it is not interchangeable with a 120-volt motor built on the same frame even though the two can look identical from the outside. Wiring a 240-volt motor into a 120-volt circuit, or the reverse, will not work correctly and should not be attempted.
Suction thins out gradually as a motor wears, the unit gets louder as the bearings age, and a burning smell or visible sparking at the brushes means the motor is near the end of its service life. Confirm the voltage rating and horn style stamped on your existing motor before ordering, and have the wiring handled by a qualified technician.
