8 lead motors offer a high degree of flexibility to the system designer in that they may
be connected in series or parallel, thus satisfying a wide range of applications.
S e r i e s C o n n e c t i o n
A series motor configuration would typically be used in applications where a
higher torque at low speeds is needed. Because this configuration has the most
inductance, the performance will start to degrade at higher speeds. Use the per
phase (or unipolar) current rating as the peak output current, or multiply the
bipolar current rating by 1.4 to determine the peak output current.

An 8 lead motor in a parallel configuration offers a more stable, but lower
torque at lower speeds. But because of the lower inductance, there will be
higher torque at higher speeds. Multiply the per phase (or unipolar) current
rating by 1.96, or the bipolar current rating by 1.4, to determine the peak output
current.
