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.
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 motor, the torque output will be

more stable at higher speeds. This configuration is also referred to as half
copper.
Full Coil Configuration
The full coil configuration on a six lead motor should be used in applica-
tions where higher torque at lower speeds is desired. This configuration is
also referred to as full copper.
