EXAMPLE: An 8 lead motor in series conguration
with
a specied unipolar current of 3.0A
3.0A per phase = 3.0 Amps Peak
An 8 lead motor in series conguration
with a specied bipolar
current of 2.8A
8 L e a d M o t o r s
SERIES CONNECTION:
When conguring the motor windings in series, use the per phase (or
unipolar) current rating as the peak output current, or multiply the bipo-
lar current rating by 1.4 to determine the peak output current.
PARALLEL CONNECTION:
When conguring 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: An 8 lead motor in parallel conguration
with a specied unipolar current of 2.0A
2.0A per phase X 2.0 = 4.0 Amps Peak
An 8 lead motor in parallel conguration
with a specied bipolar current of 2.8A
2.8 x 1.4 = 3.92 Amps Peak
WARNING! Although stepping motors will run hot when
congured correctly, damage may occur to a motor if a higher
than specied current is used. In most cases, the specied
motor currents are maximum values and should not be
exceeded!
