Why Pay More For Brushless Tools?

Look around most jobsites and you’ll see traditional brushed power tools in the hands of experienced tradies.

So, why would you pay extra for a brushless tool if the brushed tools are still doing the job? Are they worth the extra money? Is it marketing hype or are they really as good as they’re cracked up to be?

AEG Power Tools Product Manager, Mathew Bechaz answers your questions.

“A brushless motor will provide higher torque and better efficiency than a brushed motor, but the degrees of improvement will depend on the tool and the application. for different applications through firmware adjustments,” says Mathew.

“The electronics used to drive the motor can also have a significant impact on the overall system’s efficiency. For example, changing an MCU (Micro Controller Unit), or increasing the winding slot fill rate in a motor can have a significant impact on motor/system efficiency and performance,” he states.

A great example would be a circular saw making a rip cut. It requires a sudden change or large range of torque. This is where the advantages of brushless motors are obvious,” Mathew says.

“A brushless motor uses less power from the battery but delivers more ‘power out’ compared to a brushed motor,” he adds. “Also, a brushless motor will also provide much longer life than a brushed motor because they have no commutation friction between the rotor and the carbon brushes found in a brushed motor.”

Mathew says that a brushless motor generates its power in a more compact motor than a brushed version, meaning tools can be smaller and lighter.

The Technical Stuff… Electronics And Software “

Brushless motors rely on sophisticated electronics and software to function properly. Aspects of the motors’ performance can be altered and optimised for different applications through firmware adjustments,” says Mathew.

“The electronics used to drive the motor can also have a significant impact on the overall system’s efficiency. For example, changing an MCU (Micro Controller Unit), or increasing the winding slot fill rate in a motor can have a significant impact on motor/system efficiency and performance,” he states.

Why Choose AEG Brushless Technology?

Mathew says the AEG product team and engineers are constantly working to produce some of the best brushless motors in the industry, and they tailor them for Australian tradies and conditions.

“When we say ‘conditions’, we mean we study how tradies use their tools, what they expect, how they maintain them, the types of materials they work with, etc. Other countries treat the tools differently, have softer timbers, for instance, so buying tools that have been developed for over here makes sense,” he says.

“AEG also uses high grade copper for motor windings and high-grade neodymium (rare earth magnets) to produce some of the best performing brushless motors available.”

What’s Next For AEG Brushless Motors?

Mathew says it’s safe to say the industry is demanding smaller tools with the same or higher power.

“AEG engineers are committed to pushing the limits of brushless motor technology to provide the very best-in-class solution for the Aussie tradie. Our brushless tool range is always growing in both our power tools and outdoor power equipment sectors,” he says.
