Motor with FluxFocus technology Additional permanent magnets between the stator teeth help to concentrate the magnetic flux in the stator teeth. This way flux leakage is reduced and the overall torque performance improves.
Torque curve comparison Motors with FluxFocus technology reach a higher torque over the whole speed range than standard stepper motors of the same size.
Standard motor In standard stepper motors only a certain amount of the magnetic flux is used to generate torque. The non-torque producing flux or flux leakage flows past the stator teeth.
