ply the specified per phase (or unipolar) current rating by 1.4 to determine
the peak output current.
2) When configuring the motor so the full coil is used (i.e. connected from
end-to-end with the center tap floating (higher torque configuration)) use
the per phase (or unipolar) current rating as the peak output current.

SERIES CONNECTION:
When configuring the motor windings in series, 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.
PARALLEL CONNECTION:
When configuring the motor windings in parallel, multiply the per phase (or
unipolar) current rating by 2.0 or the bipolar current rating by 1.4 to determine
the peak output current.
EXAMPLE: A 6 lead motor in half coil configuration has a
specified phase current of 3.0A
3.0A x 1.4 = 4.2 Amps Peak
EXAMPLE: A 6 lead motor in full coil configuration with
a specified phase current of 3.0A
3.0A per phase = 3.0 Amps Peak
EXAMPLE: An 8 lead motor in series configuration with
a specified unipolar current of 3.0A
3.0A per phase = 3.0 Amps Peak
An 8 lead motor in series configuration with a
specified bipolar current of 2.8A
2.8 x 1.4 = 3.92 Amps Peak
