Example Connection:
Let’s consider connecting an 8-wire stepper motor to a TB6600 driver using the bipolar parallel wiring method. First, we need to identify the coils of the motor and then combine the appropriate wires for the parallel connection. Here’s how to do it step by step.
Step 1: Identify the Coils Using a Multimeter
First, we need to determine which wires belong to which coil. You can do this using a multimeter:
• Set your multimeter to resistance (ohms) mode.
• Measure the resistance between any two wires:
• If you get a low resistance reading, these two wires belong to the same coil.
• If you get infinite resistance, these two wires belong to different coils.
Example:
• Coil 1: Wire 1-2 and Wire 3-4
• Coil 2: Wire 5-6 and Wire 7-8
Each coil has two windings:
• Coil 1: (Winding 1: Wire 1-2, Winding 2: Wire 3-4)
• Coil 2: (Winding 1: Wire 5-6, Winding 2: Wire 7-8)
Step 2: Prepare the Parallel Connection
In a parallel connection, the two windings of the same coil are combined and connected to the driver.
Wiring Diagram:
• Coil 1:
Combine Wire 1 and Wire 3, then connect them to A+.
•Combine Wire 2 and Wire 4, then connect them to A-.
• Coil 2:
Combine Wire 5 and Wire 7, then connect them to B+.
Combine Wire 6 and Wire 8, then connect them to B-.
