MOONS’ linear stepper motors are available with 2-coil bipolar windings, bipolar windings motors typically have 4 leads. Bipolar motors have a single winding per phase. The current in a winding needs to be reversed in order to reverse a magnetic pole, so the driving circuit must be more complicated, typically with an H-bridge (an H bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backward.) arrangement. There are two leads per phase, none are common.
By following a series of easy steps, the below charts can be used to properly connect your motor to your drive.
- Make sure your motor and harness match. Locate the proper box below.
- Next, examine the color code of the lead wires on your motor; find the row of colors that match your wires.
- Next, connect the proper color to the appropriate terminal on your drive. If you have a Bipolar drive, the terminal on your drive will be labeled A, A-, B, B-.
If get a MOONS’ standard harness for linear step motors, the Red wire would be connected to A, Blue connected to A-, Green connected to B, and Black connected to B-.
