How to connect my steppermotor to BS2p
Archiver
Posts: 46,084
I have bought a new Nippon PF55 steppermotor. The instuktions
included were very poor. Now I need better information about how to
connect it to my stamp and what pulsewidth to use, and so on... Does
anyone have some tip or maybe even som code?

Hi Anders,
simple termonology.
The Stamp would be the 'controller'.
transistors on a board (or a seperate board with the switching
components) would be the 'driver'.
what are you using as the driver ?
You can use a 6 wire motor and 4 transistors to step the motor.
or you can use an H-bridge on each phase of the motor for 4,6 or 8
wire motors.
Typically the motors we typically use are 4,5,6 or 8 wire. Each
motor would have 2 phases. And a 4 wire has 2 set phases, 5,6 and 8
wire have 2 coils per phase and can be used as as single coils per
phase or 2 coils per phase.
A little more information is needed to let us know what you need to
do.

Some more info:
The Stepper is supposed to be both Bipolar and Unipolar.
It is an 8 wire motor, or rather two 4 wire sektions on top of each
other, with 4 wires from each.
bottom: blue, gray, purple and green.
top (middle): brown, red, orange and yellow.
On top of the stepper there is some kind of gearbox.
As Kevin says there is more info at
http://www.nipponpulse.com/PFSpecs.cfm?ID=9
f.ex. the pulsewith. But I don´t really get it anyway...
Is there perhaps anyone else who ownes a PF55?
Thankfull for any help!

Hi Anders,
the motor is really 2 section. each section has 4 wires so it is an
8 wire motor.
Select one section and label it phase A, label the other Phase B.
Isolate each coil so you have each pair of wires set apart. connect
one of each pair in each phase so that you wind up with 3 wires from
each phase.
one wire is the center tap, the other two are then the single ends of
the coils.
This becomes a 6 wire motor, and is pretty much how it is done.
(Note: at this stage, the wires may be connected wrong, but nothing
will be damaged in this testing.)
look in the files section under the folder stepper motors. the pdf
shows a schematic of a 6 wire stepper. This is for a DRIVER circuit,
your Stamp is the CONTROLLER.
Remember, with no load, you don't need the nameplate amps, you should
be able to make it spin with one quarter of the amps. (for sizing
resistor for the test) 100mA should be fine as the motor is either
5V or 12V and this crude driver will run on that voltage. at 5V and
5 ohms the current would be 1 amp, but since you are testing and not
driving a load, the 1/10th current only needs to move the shaft.
use the 'full step' pulse train from the sheet to the darlington. 4
discrete steps. keep each step 10uS or slower, as slow as you want,
hours, days....
program the Stamp to just send a pin high, pause for some time, then
send it low and the next pin high, pause... repeat.
very simple to do.
IF the motor actually goes around in a circle you got real lucky !
If it takes one step forward, then one back, then forward, then back,
that would mean one of the coils is reversed. Remember that center
tap ?
Take one coil on one phase and reverse the connections. repeat the
test. if that did not make things better, switch the wires back and
try one coil on the other phase.
Hopefully, you have 4 transistors to try this with.
The alternate method is to create an H-bridge and isolate one coil on
each phase.
