Product Description:

The AKM43G-ANCNAB00 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. It operates as a precision drive element in industrial machines, turning commanded current from a servo amplifier into tightly controlled torque and speed for coordinated motion axes. Typical duties include indexing tables, pick-and-place heads, and vision-guided tooling where repeatable positioning and rapid dynamic response are required.

Electrical and mechanical interfaces use two SpeedTec-ready connectors that allow the power and feedback leads to lock with a quarter-turn, minimizing machine changeover time. The motor is supplied without a brake, so load holding must come from external mechanisms or active servo torque. A smooth shaft permits backlash-free coupling with clamp hubs rather than keyed joints. Position data is generated by a BiSS B encoder that transmits incremental information at a native resolution of 2,048 lines per revolution; the digital link supports the AD34/AD58 feedback type. The square housing measures 84 mm across the frame, allowing close center-to-center spacing in multi-axis assemblies. Kollmorgen lists this configuration as standard, indicating that it has no custom mechanical or winding alterations.

Mounting is aligned through an IEC flange with accuracy class N, which mates directly with gearboxes or actuators without shims. The encoder stores absolute position across multiple rotations by means of its multi-turn optical register, preserving machine coordinates after power is removed. The magnetic stack uses rotor length index 3, increasing continuous torque compared with shorter variants while keeping the external dimensions unchanged. Electromagnetic behavior is set by winding designation G; this winding balances current draw and back EMF for drives operating from 230 to 480 V, allowing the motor to reach rated speed without exceeding the thermal limit of the stator laminations.
