Product details
Part 115923 is an Ametek Lamb two-stage motor, 5.7 inches across the fan housing, wound for 120 volts and built as a thru-flow unit. It is listed as fitting Miele canister vacuums, and the product title carries TriStar as a second family.
Ametek catalogs it on the Traditional Lamb platform in its commercial upright thru-flow line, lists its input power at 1150 watts, gives its replacement brush kit as 833392-67, and rates that thru-flow family at sealed vacuums up to 142 inches of water lift and flow rates up to 146 CFM. Note that Ametek places this motor in its standard flow group rather than its high performance group, which is worth knowing if you are comparing it against a hi-performance listing elsewhere.
Thru-flow construction routes the intake air across the motor windings on its way out, the arrangement used in canisters and uprights rather than in central vacuum power units, which take a sealed bypass motor instead. Two-stage construction pulls the air through two fan wheels in sequence, which is how the compact 5.7-inch frame holds suction steady as a bag loads rather than only when it is empty.
Suction that has faded and does not come back with a clean bag and filter, a bearing note that has gone from a hum to a grind or whine, running that cuts in and out, or a burning smell after a few minutes of use are the signs this motor is on its way out rather than something upstream of it. Because Miele and TriStar each used more than one motor across their canister ranges, the surest match is to compare the physical frame diameter and mounting on your old motor against this one rather than relying on the machine name alone.
