What is a slotless motor?

A slotless motor has a stator without iron teeth. In slotted motors, copper wire is wound around iron teeth. The inherent attraction between the iron teeth and the permanent magnets of the rotor cause cogging torque. Since slotless motors do not have these iron teeth, there is zero cogging torque. This is particularly beneficial for operating at slow speeds where smooth motion is essential.  Click for more information on our slotless motors.
