5. Selections & Connections about the Motors
The 3
rd
generation TB6560 stepper driver can drive 2-pahse and 4-pahse hybrid stepping motors, including 4, 6 or 8 leads.
Figure 5: Wiring diagrams for 4/6/8 leads motors
I. Connections of 4-lead Motors
4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In theory, during
adjusting stepper driver’s output current, the output current can be set to 1.4 times than the rated current of the motor on the
premise that the 1.4 times of rated current is lower than the TB6560 chip’s 3.5A peak current.
Figure 6: 4-lead Motor Connections
II. Connections of 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.
i. Half Coil Configurations
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 chopper. In setting the driver output current multiply the specified per phase (or unipolar)
current rating by 1.4 to determine the peak output current.
