What`s the torque of my stepping motors? - Electronic Circuits Projects Diagrams Free

Hello

I own two stepping motors which I collected from old HP laser printers.
They are from the same type : PM60-H418Z21B RH7-1094 AGEF from Canon.
There isn`t more written on the label.
Each stepper is 4 cm high, has a diameter of 5.7 cm and a flange for mounting. I estimate the weight of one motor to 0.3 kg. Both are unipolar and each has 6 wires.

I`ve already determine the middle-wire with my multimeter and now I want to know the correct current and amperage of the stepper. How can I find that out?
I didn`t find any information or datasheet in the i-net. Somewhere I`ve read that it is a 4 Watt motor.

What`s about the tourque of the motor ? Is it possible to move a 8 or 9 kg robot with both steppers (slow) ?

Greetings Charon

Do they look like this ..

Hello

They look like the KP6AP. The propotions are the same, but I can only guess the diameter and height of the KP6AP. Perhaps the motor on the picture is much larger then mine.
My stepper motor has also a diffrent flange and a plastic gear wheel on the drive shaft.

There is written on the label of the KP6AP that it uses 12 V.
Is this 12 V for each coil or for the whole motor ?
How can I find out the max. torque of my steppers?

is this a 6 wire motor?
12V is what can be used on the motor
during my stepper motor experience i have found that if you hold the present step take another then drop the last.. that this "holds" a lot better..

if you have a 6 wire stepper the wires
A=orange
B=blue
C=yellow
D=red
+=white
+=black

Code:

This is a sample code from my stepper motor driver program..
For x := 1 to 100 do
 Begin
  AH; DL;
  CH; AL;
  BH; CL;
  DH; BL;
  
end;

where AH BH CH DH means "active"..or energized...
Notice that i activate A , deactivate D, then activate C then deactivate A

what color are the wires..?
what are the ohms /phase?

Charon102 · 31st October 2004, 07:16 AM

Color are :

1. Coil (green / grey / brown )

2. Coil ( blue /violet /black )

The phase R is 28 Ohms.
