Re: QUESTION ABOUT SERIES OR PARALLEL ON STEPPER MOTORS

Hi,
Take a look to the following site:

http://www.microkinetics.com/contab.html

For the bipolar series and parallel connections the
time constant L/R is same. For parallel connection,
inductance lower 4 times but resistance lowers 4 times
too. So the time sonstant does not change.
Can someone explain why parallel wiring allows higher
speeds according to this approach.

Best regards
Alper

""Yes. In almost all cases, the parallel connection

and therefore, higher speeds, than the series

time
to use series
is if your stepper driver cannot supply the current
needed for parallel
connection, and
if high speed is not important. (The fix is to get a
driver that CAN
handle full rated
current in the parallel mode.)
