Like 8 lead stepping motors, 6 lead motors have two configurations available
for high speed or high torque operation. The higher speed configuration, or
half
coil, is
so described because it uses one half of the motor’s inductor wind-
ings. The higher torque configuration, or
full coil,
uses the full windings of the
phases.
H a l f C o i l C o n f i g u r a t i o n
As previously stated, the half coil configuration uses 50% of the motor phase
windings. This gives lower inductance, hence, lower torque output. Like the
parallel connection of 8 lead motor, the torque output will be more stable at
higher speeds. This configuration is also referred to as
half copper
. In setting
the driver output current multiply the specified per phase (or unipolar) current
rating by 1.4 to determine the peak output current.
F u l l C o i l C o n f i g u r a t i o n
The full coil configuration on a six lead motor should be used in applications
where higher torque at lower speeds is desired. This configuration is also
referred to as
full copper.
Use the per phase (or unipolar) current rating as the
peak output current.
