The 3.7–24 V drive references below were measured using full-step excitation and a stepper-motor tester without current limiting. They describe operating-window tests, not recommended continuous phase-current settings. Use a suitable bipolar driver, current limiting and thermal checks; do not apply DC directly across a winding. Operating frequency should avoid resonance and excessive vibration.\u003c\/p\u003e\u003cdiv style=\"overflow-x:auto\"\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eTest supply\u003c\/th\u003e\n\u003cth\u003eUpper frequency Hz \/ test current\u003c\/th\u003e\n\u003cth\u003eInput rpm at upper\u003c\/th\u003e\n\u003cth\u003eLower frequency Hz \/ test current\u003c\/th\u003e\n\u003cth\u003eInput rpm at lower\u003c\/th\u003e\n\u003cth\u003eLocked current at 0Hz\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e24 V\u003c\/td\u003e\n\u003ctd\u003e670 \/ ≤0.12 A\u003c\/td\u003e\n\u003ctd\u003e837.5\u003c\/td\u003e\n\u003ctd\u003e550 \/ ≤0.16 A\u003c\/td\u003e\n\u003ctd\u003e687.5\u003c\/td\u003e\n\u003ctd\u003e1.5 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e12 V\u003c\/td\u003e\n\u003ctd\u003e460 \/ ≤0.07 A\u003c\/td\u003e\n\u003ctd\u003e575\u003c\/td\u003e\n\u003ctd\u003e330 \/ ≤0.10 A\u003c\/td\u003e\n\u003ctd\u003e412.5\u003c\/td\u003e\n\u003ctd\u003e0.78 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e6 V\u003c\/td\u003e\n\u003ctd\u003e280 \/ ≤0.06 A\u003c\/td\u003e\n\u003ctd\u003e350\u003c\/td\u003e\n\u003ctd\u003e200 \/ ≤0.16 A\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003ctd\u003e0.4 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3.7 V\u003c\/td\u003e\n\u003ctd\u003e150 \/ ≤0.06 A\u003c\/td\u003e\n\u003ctd\u003e187.5\u003c\/td\u003e\n\u003ctd\u003e60 \/ ≤0.15 A\u003c\/td\u003e\n\u003ctd\u003e75\u003c\/td\u003e\n\u003ctd\u003e0.25 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFour-Wire Connection\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto\"\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePin\u003c\/th\u003e\n\u003cth\u003eWire\u003c\/th\u003e\n\u003cth\u003ePhase\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003eYellow\u003c\/td\u003e\n\u003ctd\u003eA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003ctd\u003eB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003eRed\u003c\/td\u003e\n\u003ctd\u003eB-bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003ctd\u003eGreen\u003c\/td\u003e\n\u003ctd\u003eA-bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cp\u003eYellow\/green form the A winding; black\/red form the B winding.
