For u, I think u need to search the forum a little more. I found very useful information here.
But as a start u can use the attached pdf, and start with L298 driver for bipolar 2A and TIP 122 half bridge for unipolar.
u can find details about wht I said and attached in the forum.
I forgot to...
*My stepper is not like that in the pdf
But at all, I don't know any of them, so as u said I did all possible pairs ohm measure
I have colors of wires: RED, GRN, BLK, BLU, ORG
RED--GRN = 1.5
RED--BLU = 1.6
RED--BLK = 1.5
RED--ORG = 1.5
GRN--BLU = 2.2
GRN--BLK = 1.8
GRN--ORG = 1.9...
Hello;
I have 5 wire stepper motor with data
" Stepping Motor
Step - Syn
SANYO DENKI, Made in Japan
DC 1.2 A, 0.72 DEG
type: 103H6500 - 7242FH6 - 1300 01"
I can't find datasheer for it
I tried a lot to know its terminals identification using ohm test, but all wires give the same value...
Thanks FvM for your positive response.
Actually my problem is that for the directly coupled or Flywheel application I don't physically understand how to get the required torque that makes the load run, and so I can choose my motor. I know there is a formula in paper but it is vague for me...
Hello,
I have the same problem.... What u did with urs? Physically our problem is how to move this directly coupled inertia??
I used those attachments
thnx
Re: Stepper Motor Control
@ Raguna:
Sorry, but what is ur terminals order? A B A* B* or what?
But firstly I think to get the 7.5 deg, it is a half step
and u r applying full step sequence
lem la
Thanks for your reply
But I don't mean changing something internally !!
I mean that instead of just passing the 1ry wire inside the hall of the sensor, I can make loops on the core. In other words i want to make turns of the 1ry wire on the upper limb of the LEM 55-p current transducer...
la55-p
HI
I am using the LEM LA 55-P for current sensing
Its conversion ration is 1:1000 i think it means 1(2ry): 1000(1ry) as 1ry nominal current is 50A and 2ry nominal current is 50mA
I am using it now for measuring current in the range of 2A, so if I am using a 68 ohm resistor I will get...
modelsim student edition
Hello,
I am using the V2pro XUP kit from Digilentinc,
As i went through the document "EDK concepts, tools, and techniques"
I reached the simulation chapter and I faced a problem. In the recommendation for simulation it is written that:
"A mixed language simulator...
use the document
XUPV2P Development System_Hardware Ref-Manual.pdf
And specially of the Expansion IOs you have 2 types:
1- user installed headers
2- right angle expansion port. this is to be used with digilentinc modules, or you can use them as you want.
A third type of IOs is the high speed...
virtex-ii pro 10.1 xbd
Thanks a lot for ur reply
I am asking about the hardware expansion cables used with I/O.
the attached photo shows the place of expansion headers.
I want to make sure of the highlighted lines above, which describes this photo
So plz tell me what u used in this place...
virtex2 user tutorial
ok,
It seems good to ask now about the expansion headers.
in the reference manual:
...."Various power supply voltages are available on the expansion connectors, 2.5V, 3.3V, and 5.0V, depending on the connector type.The expansion headers are positioned to prevent the...
inverter schematic pwm
Hi Taner,
Nice work and good PCB.
i would ask about something which i couldn't find in the posts; which algorithm do u use in PWM generation? Is it space vector modulation?
About the PCB, was it green like in photos b4 u make it, or u used something to pint it??
thanks
ac igbt
I am working on it also,
I am using Mosfets from International Rectifier www.irf.com
and also Mosfet driver IC from IR also
the inverter circuit i made still under test, but that's what i tried.
