Vacuum Motors
The vacuum motor decides drying time, and drying time decides whether the customer is satisfied. Pressure gets the soil into suspension; lift and airflow are what take it away — and a machine that leaves carpet wet will be remembered for that alone.
Motors rarely fail without warning. Loss of lift is usually gradual, and it is usually a seal or a gasket before it is the motor itself.
The range covers genuine Ametek two-stage tangential motors in 5.7 inch 1200 W and 6.6 inch 1600 W, a 4.8 inch two-stage at 230 V, a 5.7 inch three-stage bypass at 1200 W and a 7.2 inch three-stage at 230 V; a Cleanstar 5.7 inch two-stage tangential at 1100 W; and the rubber vacuum motor gasket in 5.7 inch with spring motor mounts.
How to choose
Measure the motor, do not trust the wattage. Diameter and stage count determine fit and performance. A 5.7 inch and a 6.6 inch are not interchangeable in the same housing regardless of what they draw.
More stages means more lift, not more airflow. Three-stage motors pull harder against restriction, which suits long hose runs and flood work. Two-stage motors move more air at lower restriction. Match to how the machine is actually used.
Fit a new gasket every single time. The most common reason a freshly replaced motor still will not pull lift is a reused gasket that has taken a set. It is a few dollars against an afternoon of rework.
Check the spring mounts while you are in there. Perished mounts transmit vibration into the housing and shorten the life of the new motor.
Rule out leaks first. A loose cuff, a perished lid seal or a cracked tank fitting all present as a failing motor and all cost far less to fix.
