Are brushless tools more effective?

The last few years have seen brushless motor technology dominate cordless power tools. The majority of major manufacturers now offer a range of brushless tools. But is it worth the investment?

Although brushless motors aren’t new to power tools the race was on after Makita and DeWalt launched full-blown tools with powerful battery systems to match.

Brushless Motors: The Advantages.

Brushless motor technology improves the performance of cordless power tools and extends their useful life. These motors will require virtually no maintenance.

Brushless technology has many benefits. The lack of brushes eliminates the risk of overheating or breakdowns.

The only determining factor for the service life of a brushless motor is the bearings. Brushless motors are smaller and lighter than brushed ones. This reduces vibration and noise, while making it more portable.

The efficiency of the battery is significantly improved if there’s no friction between the brushes and the rotor. The battery’s energy is maximized while heat and friction are decreased. This improves the battery’s power and battery life up to 25% compared to conventional batteries. The most recent generation of Li-Ion batteries offer up to 50% or 60% more battery life.

Because there is no friction, the motor can operate even in high-intensity applications without sparking. Brushless technology doesn’t have a contact zone which greatly reduces wear and maintenance. The brushless motor offers many advantages. It is energy-efficient and prevents overheating. Users don’t have to replace brushes. You will also find that the best cordless drills work on it.

Considering all the benefits, why not switch to brushless cordless tools?

Brushless tools cost 30% more than standard lithium-ion cordless tools. This makes them more attractive to professionals and trades who use their tools every day and want to maximize their effectiveness on every job. This is unlike a weekend DIY’er who will only use the drill when it’s needed. They won’t get more than the badge attached to the tool.

Brushless power tools can also be driven by high-performance (and expensive) lithium-ion battery because they are specifically designed to meet the needs of these motors.

Brushless motors are superior to brushed units. Brushless motors offer improved efficiency, lower maintenance and less heat. Brushless motors are now high-end power tools.
