The Brushless DC Motor. A DC motor’s life depends on its bearings and the brushes. With the introduction of the brushless motor, this dependency. was reduced to the bearing life, which in some applications is a strong advantage. In a BLDC motor the coils are fixed. and the magnet is part of the rotor...

Motors traditionally used in such handheld devices as drills and surgical cutting tools cannot be autoclaved because of the steam and tremendous heat involved in the process. "If the motor isn't completely sealed, the grease inside can liquefy and flow out of the bearings, " says Micro Mo...
