Hi I’m Lonnie Muse with Innovative IDM. Gonna talk a little bit about AC drives this morning. These things are wonderful, they have come into being and lasted a long time and there’s a real great need for them in our plants, but they are put into some places that have difficult environments. So I wanna kinda talk about the AC drive Failures.
Maybe have it medicated a little bit and what causes is. The biggest cause is not the product itself but the things that surround it. Heat is the biggest issue. It does produce a little bit of heat. It adds to the environment around it the ambient temperature. All the other products in that panel that are creating heat add to the source, if we don’t get that heat out of there or cool it down overtime this will die. Especially if it’s a dusty environment or other airborne things that are attracted to the fans in the back of the drive and aren’t cleaned out. Or the motor, I’m sorry the fan of the AC drive stops, not pulling the air through.
The biggest thing is heat we need to mitigate that. The next thing is power spikes that come through. Whether it’s caused by machines upstream or where there’s cause by lighting, or the power company, or somebody hitting a power pole outside, power spikes can kill these drives really quickly. So we need to have steps, to take steps to eliminate some of that or at least reduce it. One of the steps could be a reactor put in front of the drive that will help keep from the power spikes coming in and damaging the drive.
Another area where our drive fails is because of the other end it’s attached to the motor. If the motors not taken care of, If it’s not maintenance, if the bearings aren’t greased. There are issues that a motor, and this is related to heat as well, can short out. And if it shorts normally it’s gonna take the drive as well. It’s gonna short internally, draw too much current and will damage the drive. Check the motors.
The last, the next one I guess is age. The mean time between failures for these typical drives here is 28 years. But I guarantee you if you don’t do things ahead of time and keep it working when it gets to 10 years, 15 years, 20 years. We’re gonna start having failure. Can you imagine 20 years old and still running, some of us don’t drive cars that old. So age can affect things. Things deteriorate, change overtime, and eventually there’s failure.
The largest one and usually it happens on the front end when a drive is being installed is it’s installed incorrectly. What I have seen in my experience customers put the input power on the power leads of the drive which just tears it up. It fails. They have 24 volts for the inputs and the outputs and it puts 110 on it. So sometimes it’s installation driven. Not the product itself just improper installation.
