What does brushless string trimmer mean?

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.Click to see full answer. Similarly, what does brushless trimmer mean?A drill with a brushless motor adjusts its speed, torque, and power supply to match the task at hand. It’ll sense if you’re driving screws into a light material like drywall or a dense material like mahogany, and use only enough power to accomplish the job.Additionally, what does brushless mean? In a tool with a brushless motor, the motor adjusts according to the task. The more resistance a drill or saw senses, the more power it draws, and conversely a lack of resistance lessens the pull. Also asked, are brushless tools worth the extra money? Brushless types of drills are worth the extra money because you’ll get a better torque value in a smaller design compared to brushed models. There’s no friction to take away from the motor’s torque so the circuitry puts out as much power as possible to the work at hand.Is a brushless mower better?Brushless motors are typically 85-90% efficient whereas brushed DC motors are around 75-80% efficient. This difference in efficiency means that more of the total power used by the motor is being turned into rotational force and less is being lost as heat.
