Structural Features: Cylindrical 58‑mm‑flange motor housing; rear‑end resolver feedback assembly integrated with rotatable combined power‑feedback connector; front‑end shaft processed with DIN‑748 standard keyway; IM‑B5 flange‑mount installation form; pre‑sealed long‑life bearing chambers; no internal holding‑brake mechanism; stator‑winding embedded PTC thermal‑sensor; connector housing can rotate 360‑degree for cable‑direction adjustmentKollmorgen.
Working Principle: Servo‑drive outputs three‑phase sinusoidal current to stator windings and generates rotating magnetic‑field. Permanent‑magnet rotor rotates following magnetic‑field and delivers mechanical torque to load. Resolver captures real‑time rotor angle‑velocity information and sends sine‑cosine analog‑feedback signals back to servo‑drive. Servo‑drive executes electronic commutation and full‑closed‑loop torque‑velocity‑position algorithm calculation. PTC thermal‑sensor continuously monitors winding temperature and triggers system‑level protection upon overtemperature fault occurrenceKollmorgen.
Installation Requirements: Fasten motor rigidly on flat IM‑B5 mounting‑surface with flatness tolerance ≤ 0.1 mm; keep coupling coaxiality error below 0.1 mm; reserve minimum 50 mm rear‑side heat‑dissipation clearance; reliably connect protective‑earth terminal to cabinet grounding‑bar; adopt Kollmorgen‑specified shielded hybrid power‑feedback cables; avoid mounting near high‑temperature heat‑sources; forbid hammer‑striking motor‑shaft end‑face during assembly process.
Usage Notes: Motor windings shall never connect directly to industrial AC power‑grid; operating shaft radial‑axial load must stay within datasheet defined limits; keep connector sealing‑gasket undamaged to sustain IP65 protection‑level; PTC thermal‑protection circuit must be activated inside servo‑drive configuration; solvent‑type corrosive liquid cannot contact motor painted housing; spare‑part replacement shall match winding‑specification and resolver wiring‑pin‑definition completelyKollmorgen.
