Stepper Motor Unipolar/Bipolar 200 Steps/Rev 57×76mm 4
The motor has four colour-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.... and bipolar. A stepper motor moves one step when the direction of current flow in the field coil(s) changes, reversing the magnetic field of the stator poles. The difference between unipolar and bipolar motors lies in the may that this reversal is achieved (figure 1) : Figure 1a : BIPOLAR - with One Field Coil and Two Chargeover Switches That are Switched in the Opposite Direction.

8 Lead Wire Stepper Motor wiring configurations
The 28BJY-48 motor has one of the wires removed/cut, look for the 'bipolar motor hack on google, instructables, hackaday etc. Six wire motors are wired as shown. We won't be using the two common wires, but otherwise it's identical to the four wire version.... If in fact the coil wires are as I suspect, the easiest way to convert this motor to bi-polar is to connect both wires belonging to a phase to the same solder pad going to the Yellow / Blue wires (phase A) and White / Red (phase B).

Determine Stepper Motor Wiring Without the Stepper Motor
The sad truth is 5-phase stepper motors aren't really used anymore, due to being a pain to work with. This being said you'll have to figure out the grey code required for the stepper motor to step. This being said you'll have to figure out the grey code required for the stepper motor to step. how to connect red blue green cable to tv The four wire stepper denotes a single possible configuration and that is of a bipolar stepper motor. We do not need to bore us with details such as whether this motor is variably reluctance, permanent magnet or hybrid as that only relates to construction. What we need to realize is that two wires are for PHASE A and the other two wires are for PHASE B. Which one is PHASE A and which one is

How To Connect Bipolar Stepping Motor 4 Wires E Phase
A two phase bipolar stepper motor will have 4 leads. In a bipolar stepper we don’t have a common lead like in a uni-polar stepper motor. Hence, there is no natural reversal of In a bipolar stepper we don’t have a common lead like in a uni-polar stepper motor.
- Unipolar stepper motors with six or eight wires may be driven using bipolar drivers by leaving the phase commons disconnected, and driving the two windings of each phase together. It is also possible to use a bipolar driver to drive only one winding of each phase, leaving half of the windings unused.
- However, there is a problem with 4-wire bipolar stepper motors: they don’t have the common points of windings wired to the outside which would be needed for providing the motors with power. See the ULN2003 datasheet for more information about the IC: ULN2801,2802,2803,2804 and 2805 Darlington Array datasheet Still, it looked to me that it would still be possible to make a small bipolar
- The motor has four color-coded wires terminated with bare leads: red and yellow connect to one coil; orange and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver .
- There are six approximately 19" long leads wires that come out of this motor from two side by side holes, one hole has three wires, a red, a brown, and a black wire, and the other has 3 wires, a red, an orange, and a yellow.
