It is pronounce "Chip-ee-wah"

The company pronounces their name l"Chip-ee-wah" (like the Native American tribe) at least in English speaking countries.

The company has engineering in Toronto (among other places)and manufacturing in China. I suspect that the name sounds more like "Chee-a Poo-a" in Chinese (neglecting the all important tones that are an integral part of the language).

One more thing that folks should know about heat and motors and scaling of sizes:

Roughly speaking, the heat dissipation rate (heat power) is proportional to the area times the delta in temperature.

If you double the size of the motor, you quadruple the surface area of the motor. So... If you have the same about of heat generated per second inside your motor windings but the motor is twice as large, you will only generate 1/4 the delta in temperature that the smaller motor would generate.

Note, to first order, the drill motors and the Chiaphua motors are the same power ratings, given approprate gearing, they will do the same job in the same time generating the same electrical losses (i.e. heat).

Bottom line: If your drill motors were hot enough to boil spit (the true measure of all hot things by the way), the Chiaphua motors (geared appropriately) will only be warm to the touch*.
Think Cool Thoughts...

*for the purposes of the explanation boiling spit was taken to be 212 degrees F and room temp was taken to be 75 degrees F. In this case, "warm to the touch" works out to be about 110 degrees F (75 + (212-75)/4) Very nice indeed...
