Coil pairs are yellow\/red and black\/blue. Use a bipolar stepper driver, not a direct DC connection. Rotation follows the phase excitation sequence; the drawing views rotation from the flange side.\u003c\/p\u003e\u003cp\u003eThe motor reference is 12V. A 5–24V driver-supply range is discussed for current-controlled operation; higher supply voltage requires appropriate current limiting and does not make every included board or power supply a 24V item. Set phase current appropriately. Guidance suggests starting near 300 pulses\/s and increasing toward approximately 700 pulses\/s; usable speed depends on load and acceleration. The general 100–1300 pulses\/s control range and higher unloaded response references are not guaranteed starting frequencies.\u003c\/p\u003e\u003ch2\u003ePackage Selection\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto\"\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePackage\u003c\/th\u003e\n\u003cth\u003eContents\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Only\u003c\/td\u003e\n\u003ctd\u003eOne motor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Bracket\u003c\/td\u003e\n\u003ctd\u003eOne motor + mounting bracket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Driver\u003c\/td\u003e\n\u003ctd\u003eOne motor + push-button driver board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Enclosed Driver\u003c\/td\u003e\n\u003ctd\u003eOne motor + driver in enclosure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Bracket + Driver\u003c\/td\u003e\n\u003ctd\u003eOne motor + mounting bracket + push-button driver board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Power Supply + Driver\u003c\/td\u003e\n\u003ctd\u003eOne motor + power supply + push-button driver board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor + Bracket + Power Supply + Driver\u003c\/td\u003e\n\u003ctd\u003eOne motor + mounting bracket + power supply + push-button driver board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cp\u003eThe enclosed-driver option includes its case; other driver packages show an open board.
