Nanotec Electronic's Nema 6 and 11 Slotless BLDC Motors
Nema 6 (16 mm) and 11 (28 mm) slotless BLDC motors offer higher speeds than standard BLDC motors. The inductivity of the motor is very low and the current increases quickly in the windings. In addition, there are no iron losses. In slow operation, the lacking torque tripple has a positive effect. Since the magnetic field is not reinforced on the pole shoes as with standard BLDC motors, there is no cogging torque. The motor also turns evenly at slow speeds.
