Slotless Brushless DC Motor

  1. The slotless motor design eliminates cogging torque caused by uneven magnetic flux distribution in slotted motors.

  2. It eliminates core losses in the stator and surface wear between the stator and rotor.

  3. Slotless motors offer high durability, low electrical noise, and high efficiency, with maximum motor efficiency reaching 90%.

  4. Slotless motors are suitable for drive systems requiring rapid movement and relatively high power.
