Frame: AKM21 (58 mm flange)

Rated Power: 0.32 kW at 320 VDC

Stall Torque: 0.48 Nm

Nominal Torque: 0.39 Nm

Continuous Current: 1.58 Arms

Max Speed: 8000 rpm

Max Bus: 320 VDC

Winding: C

Feedback: EnDat 2.1 absolute multiturn, 27-bit optical

Brake: 24 VDC holding brake

Shaft: 20 mm smooth

Connectors: MLX motor/feedback pigtails

Protection: IP20 (open machine type)

Functional Features:​ Absolute multiturn eliminates homing after power loss, brake holds load during STO, low cogging.

Application Scenarios:​ Vertical lift axes, medical scanner gimbals, semiconductor pre-aligners.

Installation Requirements:​ Brake must be externally supplied via drive brake output, IP20 requires enclosed cabinet, avoid shaft radial load.

Usage Notes:​ EnDat clock must be driven by drive, never disconnect brake under load, encoder replacement needs factory calibration.

AKM motors couple natively to AKD-P / AKD-N drives with automatic parameter download.

Goldline B / M / BE2 legacy motors require resolver or incremental encoder commutation setup and are not plug-and-play on AKD without manual motor data entry.

All 230 VAC class motors (B-204, M-405, BE2-406) expect 170–340 VDC bus when driven by modern AKD 120/240 V drives; 400 V AKM65N expects 340–680 VDC bus from AKD 240/480 V drives.

Feedback cables must always be routed separately from PWM power cables regardless of motor family.

Obsolete parts (B-204-A-21, M-405-B-B1, BE2-406-G-A2) are supported only as spares, not for new designs.
