When a Super CoachVac stops pulling and the bag, the dome filter and the hose have all been ruled out, the motor is the answer. ProTeam part 100324 is the OEM motor and fan assembly for the 220-volt Super CoachVac, supplied with crimps so it goes in as a service part rather than as a bare motor you still have to wire up.
ProTeam's own CoachVac and Super CoachVac parts document lists it plainly: 100324, Motor/Fan 220V with crimps, for the Super CoachVac. That documented pairing is the reason to buy this number instead of hunting a generic 5.7-inch motor and a bag of connectors.
Built for
- Repairing an export or international Super CoachVac that has lost suction or failed outright, using the manufacturer's own part number.
- Stocking a fleet spare where a downed backpack costs a route, and waiting on a special order is not an option.
- Restoring a legacy machine. The 220-volt configuration is off ProTeam's current parts-list hub, which makes OEM stock the practical repair path rather than one option among several.
What a 5.7-inch 2-stage thru-flow motor is
The 5.7-inch figure is the fan and body diameter, the standard mounting dimension for commercial vacuum motors, not a power rating. Two-stage means two fans are stacked in series, with the first pressurizing air into the second, which raises sealed suction well above a single-stage motor at similar wattage. Through-flow, sometimes written thru-flow or flow-through, means the working airstream passes through the motor and cools the armature and brushes on its way out.
That cooling method is why through-flow motors are lighter and more compact for a given airflow, and it is also the one rule you cannot break: they are rated for clean, dry, filtered air only. Never use a through-flow motor for wet pickup, and never run one with neglected filters. Filter neglect is the leading cause of through-flow motor failure, because the motor sits directly downstream of the debris path.
Why a 220-volt version exists
These motors serve machines sold outside North America, where mains supply is typically 220 to 240 volts at 50 Hz, as well as export builds of North American machines. A 220-volt motor is not a more powerful version of the 120-volt motor; it is the same fan geometry rewound for double the voltage at roughly half the current. If you are converting or repairing an export machine, remember that the ancillaries change too, including the switch cord assembly.
How long these motors last, and how they tell you
Repair-trade figures put the original carbon brush set at roughly 700 to 900 hours, with a fresh set of brushes buying about 400 more, and a practical ceiling near 1,200 hours before bearings or the armature become the limiting factor. Brushes are considered finished when worn shorter than 3/16 inch from a new length of about 3/4 inch.
A motor on its way out announces itself: suction that keeps falling after a bag change, a filter clean and a clog check; a rising whine, squeal or grinding from the bearings; visible sparking or a heavy arcing glow at the commutator; a burnt electrical smell; carbon dust collecting in the filter chamber; and intermittent cut-outs. Two or more of those together, with filters and clogs ruled out, is the standard call to replace the motor.

A note on motor make
Both Domel and Ametek motors demonstrably shipped in these machines over the production run, and ProTeam lists separate carbon brush sets for each. ProTeam's parts document annotates this line as a Domel motor. We are not going to assert a motor manufacturer we cannot confirm for your specific unit, so before you order brushes or a commutator part, read the nameplate on the motor that is actually in your machine.

Frequently asked questions
What does 'with crimps' mean?
The assembly ships with the crimp connectors needed to splice it into the machine's wiring harness, so no separate connector kit is required. ProTeam also sells a standalone crimp set, part 100380, containing five female connectors, three male connectors and a ground connector.
Does this fit a 120-volt Super CoachVac?
No. This is the 220-volt part. The 120-volt equivalent for the Super CoachVac is ProTeam part 105162.
What else should I replace at the same time?
Common companion parts when a motor comes out are the motor compression ring with screws, part 100335, the motor ground and wire clamp set, part 100379, the motor mounting system set, part 100368, and the tetraseal, part 100014. Replace the dome and micro filters at the same time, since filter neglect is what kills through-flow motors.
Are my carbon brushes Domel or Ametek?
ProTeam lists both for this machine, part 105164 for Domel and part 101720 for Ametek. Read the motor nameplate before ordering brushes rather than assuming, because both makes shipped in these machines.
Does it include the power cord or switch?
No. The 220-volt switch cord assembly is a separate part, ProTeam 101717.
Is the Super CoachVac still supported?
The 220-volt configuration no longer appears on ProTeam's current parts-list index, so treat OEM stock as finite and confirm availability at order time.
