Rheostat for a 11000 watt kitchen blender

Posted by pristin (My Page) on

I am trying to adapt a KITCHEN BLENDER (like a Waring Blender) for use in a small laboratory where we develop TOPICAL creams. The low speed on the blender is TOO HIGH for making the cream and it destroys the cream matrix. I was wondering if I can hook up a RHEOSTAT to do this. Please help answering and also the kind of Rheostat I should use. Thanks

The few blenders I have inspected closely have a "universal" motor which does work properly with a rheostat. The power to that motor is through the controls on the blender. But the controls on the blender may not work properly with the output from any external control device.
Your post cannot be correct on the wattage.
A rheostat is a variable resistor and simply wastes the unused electricity as heat- a crude way to do it. Using a variable transformer directly to the motor, bypassing the original controls, is a much better way. Running the motor at slower speeds risks overheating no matter how the speed control is accomplished.

If it has a universal motor any of the drill/router speed control

If the blender already has a speed control it is not going to work well with another control feeding it.

Just set the blender at MAX speed and it should be ok.

There is proper laboratory equipment that will do what you need. Check for paddle mixers and homogenizers of various types. You can probably find a used one for a good price if you shop around. You may well get lucky on ebay. I get some lab equipment there.
