Machines built for 220 to 240 volt supply need a motor wound to match, and this is the single-stage thru-flow part for that job. The Ametek Lamb 11631000 (Ametek number 116310-00) is a 5.7 in single-stage motor rated at 117 CFM with 69.3 in of sealed water lift, so it is an airflow-first motor for dry pickup on higher-voltage equipment. Service departments running export machines and international-market commercial vacuums buy it as a like-for-like replacement.
A note on the voltage rating, because sources disagree. The DCP catalog lists this motor as 220V and at least one distributor lists 116310-00 as a 240 volt motor. Both describe the same 220 to 240 volt band that most Lamb export motors are wound for, but if your supply is at one end of that range, confirm the rating stamped on the motor you are replacing rather than relying on either listing.

Cross-reference
Fits
No manufacturer machine compatibility list is published for 116310-00, so none is claimed. No amperage figure is stated either, because no source we could verify publishes one for this part number. Confirm voltage, stage count, height and bracket style against the motor you are removing.
Frequently asked questions
Is it 220 volt or 240 volt?
Sources disagree. The DCP catalog lists 220V and a distributor lists 116310-00 as 240 volt. Both refer to the same 220 to 240 volt band used for export Lamb motors. Check the rating printed on the motor you are replacing before ordering.
Will it run on 120 volts?
No. It is wound for 220 to 240 volt supply and will not perform correctly on a 120V circuit.
What is the amp draw?
No verified source publishes an amperage figure for this part number, so none is stated here rather than guessing at one. The published figures are 117 CFM airflow and 69.3 in sealed vacuum.
Can it be used for wet pickup?
No. It is a thru-flow motor, so working air passes over the motor. Wet recovery requires a bypass motor.
How long do the brushes last?
Ametek publishes a carbon brush service interval of roughly 500 to 600 operating hours. Brushes worn shorter than 3/16 in should be replaced. A motor will typically accept two brush changes before the armature or bearings become the limiting part, which puts total service life in the 800 to 1200 hour range under preventive maintenance.
