Tornado EB 30/1 Complete Vacuum Motor K46237500

The complete motor (part# K46237500) is the drive unit of the Tornado EB 30/1 electric broom. It is the component that turns the roller brush, through a toothed belt running from the motor pinion to the brush pulley. On a battery sweeper of this size the motor does one job and does it constantly: every second the machine is switched on, it is under load.

It is supplied as a complete assembly — the can, the armature, the end bells and the output shaft with its pinion already fitted. That matters, because the pinion is pressed on; it is not a part you refit from an old motor on a workbench without the right tooling. Buying the complete unit avoids that problem entirely.

Symptoms of a failing motor

The usual first sign is a change in sound — a growl, a rhythmic clicking, or a whine that rises and falls — caused by worn brushes inside the motor or dry bearings. Next comes loss of torque: the brush roll stalls when it meets carpet or a patch of heavier debris, where it used to carry straight through. Intermittent running, a hot motor can after a short run, or a burnt-electrical smell all point the same way. A machine that runs normally with the belt removed but stalls with it fitted is more likely a seized brush bearing than a motor fault, so check that first — it is a much cheaper repair.

Before condemning a motor, confirm the battery is holding charge and the charger is delivering. A tired battery pack produces exactly the same weak, stalling behaviour as a worn motor, and it is the more common cause of the two.

Frequently Asked Questions

What does the complete motor do on the Tornado EB 30/1?

It drives the roller brush. A toothed belt runs from the motor pinion to the brush pulley, so the motor turns the brush that sweeps debris into the tank. It is supplied as a complete assembly including the output shaft and its pressed-on pinion.

How do I know if my motor needs replacing?

Listen for a growl, rhythmic clicking or a rising-and-falling whine, and watch for lost torque — the brush stalling on carpet or heavier debris where it used to pull through. A hot can after a short run or a burnt smell confirms it. First rule out a flat battery pack and a seized brush bearing, which produce the same symptoms far more often.

Can I move the pinion from my old motor onto a new one?

No — the pinion is pressed onto the shaft and is not intended to be transferred without press tooling. Part# K46237500 is supplied complete with the shaft and pinion fitted, which is why it is sold as an assembly.

What models is the complete motor (part# K46237500) compatible with?

The Tornado EB 30/1 Electric Broom, Models 93220 and 93222.
