Re: [PSES] EMC on Industrial Cut-Off Saws

[Doug Powell]

Same is true of other power tools, drills, vacuum cleaners, etc.  I believe ‎the thinking is these are only intermittent use.    - doug Douglas Powell http://www.linkedin.com/in/dougp01   From: Bill Stumpf Sent: Tuesday, February 3, 2015 8:14 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Reply To: Bill Stumpf Subject: Re: [PSES] EMC on Industrial Cut-Off Saws Based on inquiries I've made to the FCC & IC regarding digitally controlled power tools, the FCC currently exempts these devices from Part 15 technical regulations.  Industry Canada compliance testing should be done to ICES-001 requirements.     Bill   From: Nyffenegger, Dave [mailto:dave.nyffeneg...@bhemail.com] Sent: Monday, February 02, 2015 10:51 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] EMC on Industrial Cut-Off Saws   Code of Federal Regulations (CFR) Title 47 Telecommunication Chapter 1 Subchapter A Part 15 15.103 Exempted devices. (c) A digital device used exclusively as industrial, commercial, or medical test equipment.   Sounds like it would be FCC part 15 exempt providing the user stops operating the device upon a finding by the Commission or its representative that the device is causing harmful interference.   Don’t know about Canada yet but they usually follow the US.   -Dave     From: Kunde, Brian [mailto:brian_ku...@lecotc.com] Sent: Monday, February 02, 2015 5:12 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] EMC on Industrial Cut-Off Saws   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).   Thanks, The Other Brian     LECO Corporation Notice: This communication may contain confidential information intended for the named recipient(s) only.
