Part 2: Interfacing and Configuring
6 Lead Motors
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 windings. The higher torque configuration, or full coil,
uses the full windings of the phases.
high torque operation. The higher speed configuration, or half coil, is so described because it
uses one half of the motor’s inductor windings. The higher torque configuration, or full coil,
uses the full windings of the phases.
Half Coil Configuration
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 mo-
tor, 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 unipo-
lar) current rating by 1.4 to determine the peak output current.

Full Coil Configuration
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.
