It's part of a broader category often called Impact Wrenaches (or Impact Drivers, though those are typically for smaller screws).The key feature is its brushless motor.How Does a Brushless Motor Work?To understand the "brushless" part, it helps to know what it replaced:Brushed Motor (Old Technology): Uses physical carbon brushes that contact the commutator to transfer electrical power to the motor's spinning armature. This creates friction, sparks, heat, and wear over time.Disadvantages: Less efficient, shorter lifespan, requires more maintenance, generates more heat.Brushless Motor (New Technology): Uses an electronic controller to precisely deliver power to the motor's windings. There are no physical brushes making contact. Sensors tell the controller the exact position of the rotor, and it energizes the coils in sequence to create rotation.Advantages: More efficient, longer lifespan, no maintenance (no brushes to replace), more power in a smaller size, and better control over speed and torque.Detailed PhotosFAQQ: What can we provide ?A: We are a professional manufacturer of drill bit and have our own packing centre.
