Great tutorial on clever tech. I just had my 10 yr old ecm furnace blower motor replaced for the low, low price of $700. When I asked the service tech WtF, he said "ecm motor". So here I am. Sure, it's more efficient during its brief lifetime. But instead of being a cheap lifetime purchase, it cost me $70/yr for replacement cost. The probability that it saves $70/yr in electricity, seems quite low.

You know what? I don't care how efficient these motors are. The truth is they are far less reliable and much more costly to the consumers. Not to mention in most cases you must have the factory replacement or it won't work. So the customer is left without cooling until the factory motor can be ordered. I miss the old days when I could go to my truck and get a universal motor and get the customer working again In 20 minutes. All of this makes ECM motors very impractical compared to PSC motors.

In terms of overall comfort and nice slow start/stopping it's a nice design for homeowners that don't care to listen to the sound of the furnace while also saving a couple dollars in hydro consumption. They can drop to ridiculously low rpms for continuous fan operation that a psc cannot do. However, once that module fails and needs replacing, the manufacturer is laughing their way to the bank with the cost of the replacement that consists of about $50 or less in electronic parts is somewhere between $600 to over $1000 just for the module, not even including a motor!

i definitely understand why ECMs are attractive for system designers. but the reliability issues and the non-repairability of the drivers is why i'd rather use a 3 phase motor and a vfd. vfds are cheap, and so are inverter duty motors from companies like Weg. sure you have to locate the vfd in an enclosure with surge protection, but ones from good companies like Fuji Electric will last for decades, and are completely repairable, because the circuits are not potted in epoxy. Fuji has been making vfds since the 70s so they know what's up.

Are all ECM created equal with Chinas best? You should address the quality process your company has in place to manage warranties and failures analysis. Why are ECM much less reliable than PSC?

I'm an HVAC student. The wingdings and rotor never break. The DC converters and microprocessor reliable but can break. If there is a problem it is usually in the controller. Unfortunately replacing an old controller can be as expensive as a new motor. In PSC motors The Capacitors constantly break and when they do it can damage the expensive hermetically compressors. They are attached to. They are supposed to last 60k hours but never last that long in real life conditions with voltage spikes. I'm confident enough to buy stock in ECMs that it will replace the old motors.

@@thewallstreetjournal5675 Wait what? You are an HVAC (student)? I am an HVAC tech with 31 years experience in the field working on central cooling and heating systems day in and day out. And I am going to tell you that you have no idea what you are talking about. ECM technology IS NOT more reliable. It is far less reliable and in some cases four times more expensive than a PSC motor. I have probably replaced 50,000 capacitors and none of them have ever damaged a compressor because compressors, fan motors are all thermally protected. I have listened to countess customer complaints where the ECM motor has failed after only 2 years when their old system that had PSC motor lasted 15 years. They fail far to easily to any kind of voltage spike or surge where PSC motor didn't. Furthermore when one of these ECM motors fails you must have the factory motor to fix it. I remember the days when I could get a universal motor off my truck and get the customer working again in about 20 minutes. Today you have to special order the motor and this leaves the customer down for a day or two. That does not fly very well with the customer when the weather is extreme. Only just now has someone created a universal X 13 blower motor with the evergreen motors. When you get out of school and in the field you will see what I am talking about.

@@ironphoenix5145 I'm not sold on the bad power part. My house was struck by lightning multiple times. Yeah, in central FL. No ECM failures. That's not to say they don't' fail more often than PSC. It's just that there is more to the story than what most techs focus on. I'm more willing to bet total external static is more cause for failure than "bad electricity." Of course if I installed an inverter system, I'm going to protect it with a surge supressor and or a voltage monitor.

@@ironphoenix5145 My ECM blower motor died after 27 months. Trane warranted the parts for 10 years and labor for 2 years. The installer covered the labor part even though it was 3 months past the 2 years. Took them 3 weeks to get the replacement motor. If I had to buy or pay for a new ECM motor it would of been $700 plus. An ECM motor is a little energy efficient. The slight increase in energy efficiency doesn't make up for paying $700 plus for a new motor every 2 years and waiting 3 weeks. My old PSC blower motor lasted 25 years until I bought a new AC unit and never failed. Why did the ECM motor fail? A $0.64 varistor MOV died.

I have a a/c that has this motor driving the fan. The motor isvery expensive, as is the controller and very difficult to diagnose. I would never purchase another a/c or furnace with this technology. Much better was the older simple motor that was direct or belt driven at a reasonable replacement cost. $700.00 is way too much for a motor and $350.00 is way to expensive for the motor controller seeing they are "MADE IN CHINA". This is just greed.

I’m loving all the hate for these motors. Just went to a thermopride today that has one of these and can’t for the life of me figure out why. It heats. That’s all it does. It needs one speed for the love of god. It’s dead I think because the condensate trap got clogged and fluttered a pressure switch on and off. This cooked the board and the motor now runs constantly never mind there is no call for the motor. Furnace is ten years old. Pretty sure I’ve seen B208 blower motors running for 25 years that have been oiled like twice….
