A brushless lawn mower is a type of electric mower that uses a brushless motor instead of a brushed motor. The main difference between these two types of motors lies in their internal construction and the way they generate power. This distinction directly impacts the performance, efficiency, and maintenance requirements of the lawn mower.

Brushless vs. Brushed Motors

Brushed Motor: In a brushed motor, the rotor (the rotating part of the motor) contains coils of wire called windings, and the stator (the stationary part of the motor) has permanent magnets.

Carbon brushes are used to transfer electrical current to the windings through a commutator, which is a rotary electrical switch. As the rotor turns, the brushes and commutator experience friction, which leads to wear and tear over time, reducing the motor’s efficiency and lifespan.

Brushless Motor: In a brushless motor, the roles of the rotor and stator are reversed – the rotor contains permanent magnets, and the stator houses the windings. There are no brushes or commutators in a brushless motor.

Instead, an electronic controller senses the rotor’s position and adjusts the current flow to the windings accordingly. This design eliminates the friction and wear associated with brushes, resulting in improved efficiency, longer lifespan, and reduced maintenance.

Now that we understand the main differences between brushless and brushed lawn mowers, let’s explore how a brushless motor works and the benefits it brings to lawn mowers.
