Detailed content
Typical Specifications:
-
Frame: 446 (≈ 180 mm flange class)
-
Power Class: 5–10 kW continuous
-
Continuous Torque: 20–40 Nm (wind/stack dependent)
-
Rated Speed: 1500–3000 rpm
-
Voltage: 240/480 VAC
-
Feedback: 6-wire commutating hall + resolver or incremental encoder (legacy)
-
Insulation: Class F
-
Ingress: IP55/IP65 depending on option
-
Mount: Foot or flange, keyed shaft
Construction: Cast-aluminum end bells, laminated stator, ceramic-coated rotor magnets, separate encoder/hall harness.
Working Principle: Same FOC principle as modern AKM but requires legacy hall+resolver commutation table in AKD/S700; offset must be remapped during commissioning.
Applications: Metalworking retrofits, 1990s–2000s transfer lines, press automation, old converting machinery.
