I am learning about Variable Reluctance ( VR ) Stepper Motors. As stated in my reference, they "have no detent torque." What does this mean?

Detent torque is the torque while coils are not energised. Permanent magnets and the iron stator hold the motor in a given position without any power needing to be applied, although this force is usually much lower than the full torque - in my experience about 10%.
