API’s D Series Standard Step Motors are 4-phase hybrid, 1.8 degree motors. They are available in NEMA 23, 34, and 42 frame sizes with current ratings ranging from 1.0 amps/phase to 12.7 amps/phase. These motors offer 200 steps/revolution (Full-step) and are ideal for Half-step and Microstep operation. The standard 23 and 34 frame motors are available in 6 and 8 flying lead configurations, while the 42 frame motor is configured with a conduit box. Options for the 23 and 34 frame motors are double-ended shafts and encoder provisions. The 34 frame motor can also be configured with a conduit box.

Wiring Instructions: Before wiring step motor(s), it is recommended that some initial checks are performed. These checks involve taking resistance readings, and using an ohm-meter that can resolve 0.1 ohms or better.
