4 Lead Motors
Multiply the specified
series
motor current by 1.4 to determine the current adjustment potentiometer
value. Four Lead Motors are usually rated with their appropriate series current, as opposed to the
Phase
Current
, which is the rating for 6 and 8 lead motors.
6 Lead Motors
When configuring a 6 lead motor in a
half-coil configuration
(connected from one end of the coil to the
center tap), multiply the specified per Phase (or unipolar) current rating by 1.4 to determine the current
setting potentiometer value. This configuration will provide more torque at higher speeds when compared
to the series configuration.

When configuring the motor in a

series configuration

(connected from end to end with the

center tap floating) use the specified per Phase (or unipolar) current rating to determine the

current setting potentiometer value.

Step Motor Configurations
Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Refer to
the lead configurations and the procedures to determine their output current.
WARNING! Step motors will run hot even when configured correctly. Damage may occur to the motor if a
higher than specified current is used. Most specified motor currents are maximum values. Care should be
taken to not exceed these ratings.
