|Insert 'Hello everyone,

I recently found a STH-39D213 stepper motor and I can't find anything online about it's specs. Does anyone know how much torque it outputs?

Thanks a lot.' at: '<!-- 39987.6168865741 EOR --><A style="color:#AF4040" TITLE="Click to login and reply" REL="nofollow" HREF="/techref/login/default.asp?req=/techref/update.asp%3Fact=reply%26url=/Techref/new201707.txt%26id=39987.6168865741">+</A>'

      Hello<BR>
      <BR>
      Thanks a lot for this very nice project. I've built a linistep but used BD667s
      which have very similar characteristics as TIP122 except for a slightly lower
      maximum current. As diodes 1N4001s were used which i thought should be fast
      enough for the frequencies used here.<BR>
      <BR>
      The stepper used is a Shinano Kenshi STH-39D213 with 200steps/5.2Ohm and
      is operated at 12V.<BR>
      <BR>
      The correct wires were identified with a multimeter and the correct sequence
      with applying a small voltage at the 4 wires until the stepping sequence
      was correct.<BR>
      <BR>
      The linistep does work so far but nowhere near optimal.At around 200 rev/min
      the stepper stops. I measured the current which the motor takes and it starts
      at about 0.3A at low speed and sinks below 60mA as the speed is increased.<BR>
      <BR>
      The linistep is triggered by a NE555 circuit which generates impulses with
      near 50% duty cycle and up to 150kHz.<BR>
      <BR>
      Does anyone see a problem with my setup? Any suggestions how to improve the
      performance?<BR>
      <BR>
      I looked at the signals on pins 6 through 9 of the PIC. It was a square with
      50% duty cycle on each of them. I would have thought that in 200 step mode
      each of the darlingtons should be switched on for 25% of the time, so the
      signals should have a duty cycle of 75% and not 50%. Is that correct?<BR>
      <BR>
      Thanks a lot.<BR>
      <BR>

    Newton of Massmind</A> replies: <I>Sounds like a power supply problem. Check
    the current is more than double the per phase requirement and the voltage
    is at least a few volts more than the motors rated voltage. The 50% is due
    to high power half step mode. </I><!-- 39993.7497453704 EOR --><A style="color:#AF4040" TITLE="Click to login and reply" REL="nofollow" HREF="/techref/login/default.asp?req=/techref/update.asp%3Fact=reply%26url=/Techref/new201707.txt%26id=39993.7497453704">+</A>
