Technical Specifications:​ Frame 52 (108×108 mm); winding E; stall torque ~5 Nm class; peak ~15 Nm; 6000 rpm max; 560 VDC bus; PTC; IP54; brake 24 VDC.

Feedback:​ Resolver (CNA2R = resolver, brake, keyway, smooth/key per code).

Structural Features:​ 24 mm keyed shaft; 24 VDC spring-applied holding brake; M23 connectors; -70 denotes special winding/label/connector config.

Application Scenarios:​ Vertical lift axes, clamping slides, axes requiring static hold on power loss.

Installation Requirements:​ Brake wired to drive brake output or safe relay; mechanical brake release time considered in motion profile.

Usage Notes:​ Brake wears if used for dynamic stopping; resolver must be tuned for commutation offset; -70 suffix must match original machine BOM exactly for drop-in replacement.

AKM brushless motors (AKM22/42/44/52/53/62) share M23 SpeedTec connector philosophy, PTC thermistor, and 10-pole rotor design; they are driven by S400, PD/PicoDrive, SBD (only if modified for BLDC – SBD4 is brush-only), or MMC-SD smart drives with matching current and feedback.

Legacy S400 (S403M+PB403M-P) and PDPE210560 are digital amplifiers; SBD4-30-2101-2 is analog brush-only; MMC-SD-3.0-230-DN is standalone controller+amplifier.

All drives require isolation from mains during install, shield-terminated cables, and firmware/motor-file match before enable.

Environmental class for AKM = IP54 standard (IP65 option), ambient 0–40 °C drive / 0–60 °C motor winding limit context; UL/CE/cURus markings present on nameplates.
