Published: Last Updated on
Red Lawn Mower

With advancements in technology, not just lawn mowers but their electric motors have also seen upgrades, and thus, brushless lawn mowers are now becoming quite common. 

Lawn mowers powered by brushless technology automatically adapt to the power required by the blades to be more battery-efficient, powerful, quieter, and less maintenance hungry. 

Thus, switching to a brushless lawn mower is the wisest decision. Continue reading to learn more about this mower type, including how the technology actually works. So, let’s start without further ado. 

Key Takeaways: 

  • A brushless lawn mower’s motor includes a permanent magnet that rotates at its center and a coil that surrounds this magnet. 
  • A brushless motor works more efficiently by using a combination of external wiring and a sensor to deliver appropriate electricity to the coils.
  • Adaptability to power needs, quieter operation, and adequate battery usage are some best advantages of a brushless lawn mower. 
  • If you’re looking for the best brushless lawn mower brand, EGO, RYOBI, DeWALT, Greenworks, and Toro are some options. 

How Brushless Motor Technology Works 

Before we go into the features, capabilities, and maintenance requirements of brushless mowers, let’s first understand the working principle of brushless motor technology. 

Like any brushed motor, brushless motors are made of 2 main components – a permanent magnet that rotates at its center and a coil that surrounds this magnet. But instead of the coil rotating inside the magnet of brushed motors for power generation, a brushless motor uses a system of external wiring and a sensor for the same. 

This configuration doesn’t lead to mechanical friction or heat and noise production.

Features & Capabilities Of Brushless Lawn Mowers 

Below are some cool features & capabilities of brushless lawn mowers. 

  • Quieter Operation 

Thanks to no brushes inside the motor that are the primary source of unwanted noise, a brushless lawn mower means a quiet operation. Thus, be it early morning or evening, mow your lawn without worrying about disturbing anyone around you.  

  • Enhanced Efficiency 

Since there’s no friction inside the motor due to the brushless design, brushless mowers operate more efficiently than brushed ones. In numbers, they are 80%-90% more efficient than brushed mowers, with a 60%-75% efficiency.

  • Extremely Low Maintenance Cost 

Electric lawn mowers, if we ignore the motor for a moment, require less maintenance and, when coupled with brushless motors, the overall maintenance cost goes down further. This is because there are no pesky maintenance-hungry brushes to take care of. 

  • Not Much Risk Of Overheating 

There’s not much risk of overheating in brushless lawn mowers as the coils sit on the outer edge of the motor, enabling an instant cool down. 

  • More Torque 

Another benefit of the coil sitting on the outer edge of the motor is that it lets the permanent magnet wrap more wire and elongate the coil size. As a result, the mower produces more torque and power. 

So, these were some advantages of brushless lawn mowers.

Maintenance Of Brushless Lawn Mowers 

The proper functioning of brushless lawn mowers depends on how well you maintain them, especially the brushless motor inside. For starters, below are some non-negotiable maintenance requirements of every brushless lawn mower. 

  • Inspect the motor for corrosion, dirt buildup, burnt odor, etc. If you find any of these, immediately act to preserve the motor’s efficiency. 
  • Frequently lubricate the moving parts of the brushless motor, especially the bearings. Besides, the 4 wheels must also be properly lubricated with a high-grade lubricant, for example, WD-40.
  • Examine the bolts and fasteners of your lawn mower and tighten them, if required. 
  • Clear the undercarriage of your mower from grass clippings, mud, and other objects that may interfere with the blade’s functioning.
