I am not at all familiar with this category of products so please excuse my ignorance which is an industrial cut-off saw with a 5hp electric motor for cutting steel rods, and such.
Most of these basic model saws have no high frequency devices and brushless AC motors so they do not generate EMI. However, the more expensive models have Inverters (Frequency Drives) to slow start/stop the motor and act as a break. We evaluated a saw from a company who says they do not require EMC testing on their saws even when they use the Inverter, as long as they follow the installation instructions from the inverter manufacturer (yea, I just about fell out of my chair). We tested one of these saws and failed CISPR 11 Class A Conducted Emissions by 50db (if was a prototype saw not on the market). How do these people sleep at night? So here is my question. Does the US and Canada require Emissions testing on Industrial Saws? Same question for Europe. I assume EN 55011 Class A is mandatory in Europe on such a devices. Please confirm (sanity check).
