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
8 L e a d M o t o r s
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 bipo-
lar 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:
An 8 lead motor in parallel configuration
with a specified unipolar current of 2.0A
2.0A per phase X 2.0 = 4.0 Amps Peak
An 8 lead motor in parallel configuration
with
a specified bipolar current of 2.8A
2.8 x 1.4 = 3.92 Amps Peak
WARNING! Although stepping motors will run hot when
configured correctly, damage may occur to a motor if a higher
than specified current is used. In most cases, the specified
motor currents are maximum values and should not be
exceeded!
