An Elinco slotless brushless DC (SBLDC) motor consists of a stator winding positioned inside a laminated stator ring (without conventional teeth) and a permanent magnet motor. This provides more peripheral space for the stator winding.
This also allows more magnet surface area and more air gap flux. Powerful rare earth magnets provide high torque to motor weight ratios. The absence of stator teeth enables more winding copper and power density which can develop more torque. It also eliminates torque cogging and minimizes audible noise.
