<p>A linear brushless DC motor is disclosed which provides reduced detent force by way of a stack (150) that features end teeth (152, 154) that are formed to be wedge shaped, and which has a length in the direction of motion which is approximately equal to (NP + 1/2) x pole pitch, where Np equals the number of poles covered by the armature of the brushless DC motor, and the pole pitch equals a distance between centers of two adjacent magnets (164) of opposite polarity in a field assembly (162) of the linear brushless DC motor.</p> |
