microzone Posted June 9, 2006 Report Share Posted June 9, 2006 I just get a stepper motor from my old printer and plan to use it but I do not know its connection. Does anyone has its data sheet? I guess it is a bipolar stepper motor because it has only 4 wires. My stepper motor information is as below:-QH4-4387SMJ40-4878-A24.12V7.5ohmFDK Quote Link to comment Share on other sites More sharing options...
zak4000 Posted June 19, 2006 Report Share Posted June 19, 2006 You could get a ohmmeter and test the leads to see the resistance of them.High= No coil between those 2 tested leadsLow (or near low)= Theres a coil between those 2 tested leads Quote Link to comment Share on other sites More sharing options...
