Abstract
A stator for a stepping motor, the stator having a plurality of salient poles and at least two windings, each winding comprising at least two conductors each of which is wound upon one or more separate poles. The conductors of each winding may be connected either in series or in parallel. This winding arrangement is particularly advantageous when the conductors of each winding are connected in series and driven with a bipolar drive, as problems which exist with bifilar windings, such as high conductor-to-conductor potentials and inductive spikes, are avoided.
