Long- Vs. Short-Term Cost: Electric Motor Manufacturers Take Note
If a motor is more efficient, it will save electricity. Simple, right?
Now, is it more expensive in the short term to switch to a powder metal part made from SMC? Most likely. Soft magnetic composite powder often costs more than the competing steel laminate it’s replacing.
So, yes, maybe you’ll have to use a little more copper, which is indeed an expensive metal. Or maybe you’ll have to alter your design slightly, which tacks on a little more cost.
In the end, it won’t matter. Your customers can spend more up front to save later.
You can absolutely conserve 5%-20% on electricity with the right powder metal. The exact percentage will depend on what alternative you’re comparing SMC with.
The long-term electricity savings are something you can promote to your own customers and pass the savings on to them if you wish. Since it’ll be more energy-efficient, you can also promote your electric motor as being environmentally friendly.
How Soft Magnetic Composite Can Drive a Super Efficient Electric Motor
You’ve learned that electric motor manufacturers can save customers money with soft magnetic composites. You’re probably wondering how exactly it works.
We’ve all picked up an electric motor. You feel the heat that’s being generated. That heat is actually an inefficiency. You’ve seen this in your home computer and other electronics, too.
If you take what’s being converted into heat and just convert that into electromechanical energy, your motor will run more efficiently. So, higher efficiencies will generate less heat, and more of that energy turns into mechanical energy -- where it should be.
An example of where this comes into play is the modern air conditioning system. They run all the time. If you want to install a high-efficiency motor to cut your cooling costs, it’s much easier to do with soft magnetic composite parts. Then you can match the cooling load to what the actual compressor or fan is doing.
This little-known long-term savings trick is reminiscent of another secret we’ve shared with you. In some cases you can create a single SMC component that can serve the same function as hundreds of pieces of lamination assembly. So paying a little more up front for raw soft magnetic material will cost less in the long run.
