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

8 Lead Motors

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: 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!
