Common stepper motor configurations have 4, 5 or 6 wires corresponding to phases wired as follows:[Bipolar stepper motor wiring][Unipolar stepper motor wiring][Unipolar stepper motor wiring]4 wire bipolar stepper motor5 wire unipolar stepper motor(unipolar drive only)6 wire unipolar stepper motor(drive as bipolar by ignoring centre tap)Less common stepper motor configurations have 8 or 9 wires… text/html 2022-08-04T16:57:12+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/actuator/stepper/sth39d125?rev=1659589032&do=diff [STH-39D125] Stepper Description Model STH-39D125Manufacturer Shinano KenshiDrive method bipolarNumber of phases 2Winding colours brown-black, orange-yellowStep angle(deg)/step1.8VoltageV12CurrentA/phase-Winding resistanceohm/phase144InductancemH/phase-Holding torquemN*m-Detent torquemN*m-Rotor inertiag*cm*cm-Heightmm33Widthmm39 (Nema 15)Shaft lengthmm22Shaft diametermm5Weightg-Insulation Class -Insulation resistance -Dielectric strength -Operating temperature range(deg)C-Allowable temperatu… text/html 2022-08-07T14:44:01+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/actuator/stepper/stp42d0009?rev=1659840241&do=diff [STP42D0009] Stepper Description Model STP-42D0009Manufacturer Shinano Kenshi?Drive method bipolarNumber of phases 2Winding colours blue-grey, grey-grey (adjacent wires)Step angle(deg)/step1.8VoltageV-CurrentA/phase-Winding resistanceohm/phase1.5InductancemH/phase-Holding torquemN*m-Detent torquemN*m-Rotor inertiag*cm*cm-Heightmm27.5Widthmm42 (Nema 17)Shaft lengthmm7Shaft diametermm4Weightg-Insulation Class -Insulation resistance -Dielectric strength -Operating temperature range(deg)C-Allowa…
