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. In setting the

driver output current multiply the specified per phase (or unipolar) 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.
