Cordless Leaf Blower Motors – Everything You Need to Know

Motors are the heart of Cordless leaf blower. They are responsible for generating the power that drives the fan and clearing leaves, debris, and snow from your yard. When choosing a cordless leaf blower motor, you need to consider the size of your yard, the type of debris you will be blowing, your budget, and the RPM, amp hour, brushless or brushed design, maintenance, and safety features of the motor. Here is an overview of the different cordless leaf blower motor types and the factors you must consider when choosing the right motor.

Cordless Leaf Blower Motors – An Ultimate Guide

There are two types of motors used in the cordless leaf blowers.

  • Brushed Motor
  • Brushless Motor

Brushed Motors

A brushed motor in a cordless leaf blower is an electric motor that utilizes brushes and a commutator to generate rotational motion. It’s a common motor design used in many cordless power tools, including leaf blowers.

Brushed Motors

How Does Brushed Motor Work?

Brushes and Commutator

A brushed motor consists of brushes and a commutator. The brushes are in contact with the commutator, a split ring connected to the motor’s armature.

Electromagnetic Field

When electricity flows through the brushes, it creates an electromagnetic field within the motor.

Rotational Force

The interaction between the electromagnetic field and the armature causes the armature to rotate, producing mechanical energy.


  • Simple and cost-effective
  • Good for many cordless tools
  • Provides consistent power
  • Easy maintenance
  • Offers good torque at low speeds
  • Affordable replacement parts
  • Longevity with proper care


  • Limited efficiency
  • Brushes and commutator wear over time

Brushless Motors

A brushless motor in a cordless leaf blower is an advanced electric motor design that eliminates brushes and commutators, offering improved efficiency and durability.

Brushless Motors

How Brushless Motor Works?

Permanent Magnets

Brushless motors have permanent magnets on the rotor (inner part) and stationary windings on the stator (outer part).

Electronic Controller

An electronic controller (ESC) manages power distribution, constantly adjusting the current to the windings based on rotor position feedback.

Rotor Rotation

The ESC energizes specific windings in the stator to create a rotating magnetic field that interacts with the permanent magnets, causing the rotor to turn.


  • Higher efficiency
  • Longer lifespan
  • Reduced heat generation
  • Increased power-to-weight ratio
  • Improved battery life
  • Smoother operation
  • Less maintenance required


  • Higher initial cost
  • More complex electronics

Is a Brushless or Brushed Motor Cordless Leaf Blower Good?

Choosing between a brushless and brushed motor for a cordless leaf blower depends on various factors, each offering distinct advantages and limitations. Let’s weigh the options.


Brushless: Higher efficiency, translating to longer battery life and better performance. Perfect for extended use and demanding tasks.

Brushed: Lower efficiency, potentially leading to shorter battery life and reduced overall performance.


Brushless: Long-lasting due to fewer moving parts. Minimal wear and tear make it a durable choice.

Brushed: Prone to wear and tear with brushes and commutators, requiring more maintenance.


Brushless: Virtually maintenance-free with no brushes or commutators to replace or clean.

Brushed: Demands periodic brush replacement and commutator cleaning, increasing maintenance efforts.

Power-to-Weight Ratio

Brushless: A better power-to-weight ratio results in a lighter, more powerful, and compact design.

Brushed: Tends to be bulkier and heavier for similar power output.


Brushless: Higher initial cost offset by long-term savings through reduced maintenance and improved battery life.

Brushed: Lower initial cost, but ongoing maintenance expenses and potentially shorter battery life can add up.

brushed vs brushless cordless leaf blower motors

Noise and Heat

Brushless: Generates less heat and operates more quietly due to its efficiency.

Brushed: This may produce more heat and noise during operation.


Brushless: Ideal for professionals and frequent users requiring long-lasting, high-performance tools.

Brushed: Suitable for occasional or light-duty use where budget considerations take precedence.

Expert Advice

For those prioritizing long-term performance, efficiency, and durability, brushless motors are the superior choice. 

However, if budget constraints and occasional use are primary considerations, a brushed motor may still serve your needs adequately.

How to Choose the Right Cordless Leaf Blower Motor?

Size of the Yard

Consider the size of your yard. The size of your yard will determine the amount of power you need from your leaf blower motor.

You can get away with a less powerful motor if you have a small yard. However, if you have a large yard, you need a more powerful motor to clear leaves quickly and efficiently.

Type of Debris

Consider the type of debris you will be blowing. If you will be blowing light debris, such as leaves, you can get away with a less powerful motor.

However, you will need a more powerful motor if you blow heavier debris like gravel or snow.

Battery Type

Consider the battery type of Cordless leaf blowers. These blowers use either lithium-ion or nickel-cadmium batteries.

Nickel-cadmium batteries are less expensive but don’t last as long and don’t provide as much power.

Lithium-ion batteries are more expensive but have a longer lifespan and can provide more power.

Weight of the Leaf Blower

Consider the weight of the leaf blower. A heavier leaf blower will be more difficult to maneuver, so it’s important to choose a model that is lightweight enough for you to use comfortably.


Consider the warranty. Most cordless leaf blowers come with a warranty that covers defects and malfunctions.

Make sure to choose a model with a warranty you are comfortable with.

Additional Expert Tips

From a Technical Aspect

The motor’s RPM (revolutions per minute) is an important factor. A higher RPM means that the motor can move more air, which will help you clear leaves more quickly.

The motor’s amp hour (Ah) rating is also important. This rating indicates how much power the motor can deliver. A higher Ah rating means the motor can run on a single charge for longer periods.

The motor’s brushless or brushed design is also something to consider. Brushless motors are more efficient and have a longer lifespan than brushed motors.

From a Maintenance Aspect

It is important to regularly clean and lubricate the motor to keep it running smoothly.

You should also inspect the motor for wear and tear and replace damaged parts.

From a Safety Aspect

Make sure that the motor is properly grounded to prevent electrical shock.

Always wear safety goggles when using a leaf blower to protect your eyes from debris.

How to Maintain a Cordless Leaf Blower Motor?

Here are some tips on maintaining a cordless leaf blower motor, both brushed and brushless.

Clean the air filter regularly. The air filter helps to keep dirt and debris out of the motor, which can help to extend its lifespan.

Lubricate the motor regularly. Lubrication helps to keep the motor running smoothly and prevents wear and tear.

Inspect the motor for wear and tear. Look for signs of damage, such as loose or damaged wires, burnt or corroded components, and excessive heat.

Replace worn or damaged parts. If you find any worn or damaged parts, replace them immediately to prevent further damage to the motor.

Store the leaf blower properly. Store the leaf blower in a cool, dry place when not using it.

Bonus Tips for Maintaining a Brushed Motor

Replace the brushes regularly. The brushes wear down over time and need to be replaced.

Adjust the gap between the brushes and the commutator. The gap should be adjusted regularly to ensure the brushes make good contact with the commutator.

Use a high-quality lubricant. A high-quality lubricant will help to keep the motor running smoothly and prevent wear and tear.

Bonus Tips for Maintaining a Brushless Motor

Avoid overloading the motor. Overloading the motor can shorten its lifespan.

Do not use the leaf blower in wet conditions. Water can damage the motor.

Keep the motor clean and free of debris. Dirt and debris can build up and cause the motor to overheat.

Final Words

The decision between a brushless or brushed motor is a balancing act, considering factors like efficiency, durability, maintenance, cost, and application. Brushless motors undeniably take the lead, offering enhanced efficiency, extended longevity, and superior performance. Their initial cost, though higher, is offset by long-term savings. However, brushed motors remain a viable option for occasional users on a budget, albeit with higher maintenance demands.
