Rising input costs are killing industrial businesses.
Electricity bills, raw materials, labor…they all keep going up. For manufacturers, energy is the cost that really hurts.
Here’s the problem:
Industrial electricity prices are at or near all-time highs. If you continue to operate old inefficient equipment, you will be priced out of your own market.
The good news?
One of the simplest steps you can take to reduce your energy costs and guard against future increases is to upgrade to permanent magnet motors.
Let’s jump in…

Why Rising Input Costs Are A Big Deal
Let’s get real for a second. The industrial sector is in a tough spot.
In a recent industry report, almost 90% of businesses have experienced an increase in energy costs over the last 5 years. Now that’s a statistic you can’t overlook.
Think about it like this…
Say your electric bill increases 20%, but you can’t increase your product prices. Your profit margin shrinks. At some point, you have two choices:
- Raise your prices (and risk losing customers)
- Cut your costs (and stay competitive)
Most manufacturers can’t afford to lose customers. Cutting costs is the smart move.
But where do you even start?
The solution is obvious… Just look at your largest energy user. For most industrial facilities it’s electric motors. Motors power pumps, fans, conveyors, compressors. They are the quiet backbone of your entire operation.
And if you’re using old induction motors, you are literally bleeding money every hour they are running. That’s where trusted specialist suppliers such as RJW Motors and Inverters can make a real difference. The correct permanent magnet motors and variable speed drives can reduce your site-wide energy consumption dramatically. It’s one of the most cost-effective ways to reduce your input costs without interfering with production.
Here’s why this matters:
Industry data indicates electricity prices at two-thirds above the median of comparable nations. That’s a massive disadvantage if competitors have access to cheaper power.
So what can actually be done about it?
What Are Permanent Magnet Motors?
A permanent magnet motor (PMM) is an electric motor that uses permanent magnets in the rotor instead of electromagnets.
This sounds like a small change… But it makes a massive difference in performance.
Conventional induction motors must “generate” their own magnetic field with electricity. This consumes additional power. Permanent magnet motors have no need to do this as the magnets are already doing the work for free.
The result?
- Less energy wasted as heat
- Higher efficiency across all speeds
- More torque from a smaller package
- Longer motor life with less maintenance
Pretty cool, right?
Permanent magnet motors are not a new technology. However, the evolution of neodymium magnets has made them much more cost effective and practical for widespread industrial application. They are found in many applications from factory automation to HVAC to renewable energy systems.
How Permanent Magnet Motors Cut Your Energy Bill
Let’s talk numbers. This is where permanent magnet motors really shine.
Industry experts estimate that permanent magnet motors can reach efficiency levels of 90-97 percent. Compare that to conventional induction motors which work at 80-90 percent efficiency.
That doesn’t sound like a lot on paper. But running motors 24/7 throughout an entire facility means a few percentage points of efficiency will save thousands of pounds every year.
Here’s what that means in the real world:
Suppose a factory has 20 motors running, and each of them draws about 50 kW of power. Now replacing them with permanent magnet motors, with 7% better efficiency, would save 70 kW of power for each hour of operation. If that is extrapolated to thousands of hours of operation per year, the result is a significant amount of savings.
Other benefits include:
- Lower heat output (which reduces cooling costs)
- Better speed control for variable load applications
- Reduced maintenance bills over the motor’s lifespan
- Smaller footprint, which frees up factory floor space
And the best part? There’s no need to tear out an entire operation to switch. Most facilities simply upgrade motors piecemeal as they reach end of life.
Practical Steps To Future-Proof Your Business
Want to start hedging a business from cost increases? Here is a step by step plan that has proven to work.
Audit Your Current Motor Fleet
Start by doing an energy audit. Walk around the facility and note down:
- How many motors are running
- What size and type they are (induction, DC, etc.)
- How old they are
- How many hours they run per year
This gives a baseline. You can’t improve what you don’t measure.
Prioritize The Biggest Energy Users
Start with motors that have the longest runtimes or highest energy consumption. These will have the quickest payback for a permanent magnet upgrade.
Ponder pumps, fans, compressors and any motor that runs 24/7. These will return the investment in the fastest way possible.
Plan Your Upgrade Strategy
There is no need to change all motors at the same time. Schedule a 2-3 year phased upgrade:
- Replace motors as they fail (this is the cheapest approach)
- Proactively upgrade the highest-consumption motors first
- Pair new motors with variable speed drives for maximum savings
The power combo of a permanent magnet motor and a variable speed drive is a serious “hack” for any factory. Fine tune motor speed to load requirements, reducing energy waste even more.
Track Your Savings
After the upgrade, measure again. This will show how much energy is being saved, and where to spend money next.
Keep the data clean, and it makes a compelling case to expand motor upgrades throughout the organisation.
Final Thoughts
Escalating input costs are here to stay. In fact, they are likely to continue to accelerate unless and until proactive action is taken by manufacturers.
Permanent magnet motors offer a tangible, concrete means of resistance. They help to lower the electricity bill, reduce maintenance expenses and make an operation more competitive with both domestic and foreign rivals.
To quickly recap:
- Industrial energy prices are among the highest they’ve ever been
- Permanent magnet motors achieve 90-97% efficiency vs 80-90% for traditional motors
- Upgrading can save thousands of pounds per year per motor
- A phased upgrade plan makes the switch affordable
- Pairing with variable speed drives maximum savings
The companies that future proof their businesses today will be the ones left standing when input costs soar again. Don’t wait until the energy bill forces the decision… Start upgrading now.
