Tornado Vacuum Motor K46101083

This is the genuine Tacony suction motor (part# K46101083) fitted to the Tornado Strike TV190-W10-U and the Tornado Zephyr TV570-Q03-U. On a dual-motor machine like the Strike it is the one that makes the suction — the brush roll has its own separate motor — so a failure here takes the vacuum out of service even though the brush still turns.

Compatible Models for the Vacuum Motor

• Tornado Strike TV190-W10-U cordless upright vacuum
• Tornado Zephyr TV570-Q03-U cordless upright vacuum

This part is not exclusive to the Strike. Tacony’s parts records list part# K46101083 against two machines — the Strike TV190-W10-U and the Zephyr TV570-Q03-U — which is why this listing carries the brand rather than a single model name in its title. The two machines are built on the same cordless platform under different names and share the great majority of their suction-side parts.

What the Vacuum Motor does

It is the 36-volt suction motor that sits in the rear housing behind the filtration, drawing air through the fleece bag and HEPA cartridge. It is supplied as the bare motor; the seal, the acoustic foams and the wiring harness are separate parts. Running a battery machine means this motor is matched to the pack voltage and the electronics, which is why a generic replacement is not an option.

Signs the Vacuum Motor needs replacing

A motor on the way out usually announces itself by sound before it fails: a rising whine, a rumble that comes and goes with the machine tipped, or a screech on start-up all point at bearings. Other signs are suction that has dropped with a clean bag and a clear airway, a burning smell, or a machine that cuts out under load and restarts after a rest. Brush dust inside the rear housing is a late-stage sign and means replacement rather than repair.

Fitting the Vacuum Motor

This is a job for someone comfortable inside the machine. Disconnect the battery and leave it out. Remove the rear cover, note the exact position of the acoustic foams and the motor seal, then release the wiring at the connector rather than pulling on the leads. Fit the new motor with a new seal if the old one is compressed, reseat every foam in its original place, and dress the harness clear of the impeller housing before the cover goes back. Test on a bench with a fresh bag before the machine goes back into service.

Frequently Asked Questions

Is this the brush motor or the suction motor?

The suction motor. The Strike is a dual-motor machine: the brush roll is driven by a separate brush motor (part# K47755900) in the cleaning head, and this part is the one that generates airflow.

Does it come with the seal and foams?

No. Part# K46101083 is the motor itself. The motor seal (part# K53635510) and the acoustic foams each carry their own part numbers, and it is worth replacing any that are compressed or oil-stained while the machine is open.

My suction has dropped but the motor sounds normal. Is it the motor?

Probably not. Check the fleece bag, the HEPA cartridge, the hose from the bottom housing and the filter cover seal first — restricted airflow and air leaks account for most suction complaints. A motor at fault almost always sounds different as well as performing worse.
