What happens to brushes in a brushless motor?
A brushless motor loses the brushes and the commutator. And the locations of the magnets and windings are reversed: The magnets are on the conventional motor shaft and the copper windings of the armature are fixed and surround the shaft. Instead of brushes and a commutator, a small circuit board coordinates the energy delivery to the windings.
Why are brushless motors so powerful?
Because the copper windings are on the outside of the motor configuration, there is room to make them larger. Brushless motors also don't have the friction and voltage drop that brushes create by dragging against the spinning commutator.
What are the parts of a brushed motor?
A traditional brushed motor is made up of four basic parts: carbon brushes, a ring of magnets, an armature, and a commutator. The magnets and brushes are stationary, while the armature and commutator rotate together on the motor shaft within the magnets. Makita. When the motor is energized, a charge travels from the battery, through the brushes, ...
How does a motor work when energized?
When the motor is energized, a charge travels from the battery, through the brushes, and into the commutator. (The brushes are spring-loaded to maintain physical contact with the commutator.) The commutator then passes the charge on to the armature, which is made up of copper windings (they look like bundles of copper wire). The windings are magnetized by the charge and push against the stationary ring of magnets that surround it, forcing the armature assembly to spin. The spin doesn't stop until the charge from the battery stops.
What is a small circuit board?
Instead of brushes and a commutator , a small circuit board coordinates the energy delivery to the windings. Because the electronics communicate directly with the stationary windings, the tool adjusts according to the task—which is why the companies market these as "smarter" tools.

What is a Ryobi brushless mower?
Ryobi makes two brushless mower models, the RY18LMX40A and RY18LMX37A. They are not as powerful as the Makita offerings, and reviewers note that cutting thick, tall grass can be a problem, but they are more than capable of handling most typical lawns. The two models are very similar, differing only in the width of the cutting area and the size of the equipped grass catcher bag. Both are compatible with Ryobi’s handy One+ lithium-ion batteries, so if you already have a Ryobi One+ tool, you’ll find the batteries and charger interchangeable.
Why are brushless mowers better than brushed mowers?
In practice, the primary benefit of any brushless tool is increased tool lifespan. Brushless motors are often rated for five to ten times the usable life of their brushed counterparts. Although you’re unlikely to find any lawn mower described as “quiet”, the reduced noise output might make mowing your lawn a slightly more comfortable experience as well. Brushless motors are also more energy-efficient, since they don’t have a constant source of internal friction they need to expend power to overcome. That makes them better for the environment and for your energy bill, and means they’ll last a bit longer on a charge, assuming the same battery capacity. However, you will pay a price premium for these advantages.
How does a brushed motor work?
In a traditional brushed motor, the spinning shaft contains the electromagnet.
Do brushless mowers use lithium batteries?
Cost is obviously a factor, and you’ll need to consider the cost of batteries as well. Almost all brushless motors use lithium-ion batteries, which have similar advantages to brushless motors: compared to conventional lead-acid batteries, they’re safer, longer-lasting, and more efficient, but you’ll pay more. If you already have tools with compatible batteries from the same manufacturer, the ability to use your existing batteries in a new mower might well save you over a hundred dollars.
