The brushless motor uses magnets for rotation instead of a squirrel cage. Unlike traditional motors, it doesn't require brushes to power the windings, eliminating wear and energy losses associated with these components. The windings are integrated into the stator (fixed part) rather than the rotor (moving part), which enhances heat dissipation, reduces inertia, and increases torque and performance, especially for devices requiring rapid speed variations. Wireless tools with this technology thus provide optimal torque at all speeds.
