Slotless Brushless DC Motor
Technology
The winding of a slotless brushless DC motor is not wound around stator slots as in a traditional brushless motor. Instead, the stator is a cylindrically shaped woven structure placed within the motor's air gap between the cyclindrical lamination stack and the rotor assembly. The slotless design eliminates cogging, yielding a motor with very smooth rotation, and reduced vibration and audible noise.
