Five-Phase Stepper Motor and Driver Set
The Autonics A8K-M566 combines a five-phase stepper motor with matching drivers in a single box. It delivers a basic step angle of 0.72 degrees in full-step mode and 0.36 degrees in half-step mode. Maximum holding torque reaches 8.3 kgf.cm with a rated current of 1.4 A per phase. The unit features a pentagon wire connection and an IP30 protection structure.
Motion Control Builders Needing Fine Resolution
Engineers who require precise positioning in automation rigs or test equipment will benefit from the small step angles and 280 g·cm² rotor inertia. The IP30 rating limits use to clean, dry indoor environments, so outdoor or wash-down installations should look elsewhere. Buyers needing integrated controllers or higher ingress protection must select a different package.
0.72-Degree Full-Step Angle
The 0.72-degree full-step angle determines the minimum mechanical increment without microstepping. This value directly governs positioning granularity for lead-screw or belt-driven axes. Verify that the required resolution matches this fixed characteristic before purchasing.

Questions about this item
Should I choose the full-step or half-step setting for my application?
Full-step gives 0.72° per step and half-step gives 0.36° per step; select half-step when you need finer positioning resolution.
What does the 8.3 kgf·cm holding torque mean once the motor is installed?
It is the maximum torque the motor can hold while energised at 1.4 A per phase; actual available torque drops as speed increases.
How does the Pentagon wiring and IP30 rating affect drive selection and environment?
Pentagon wiring requires a compatible 5-phase drive, and IP30 protects only against solid objects — no water or dust protection.
