Structural Features: Cylindrical compact 40‑mm‑flange housing; rear‑end resolver feedback housing integrated with combined power‑feedback circular connector; front‑end smooth round shaft without keyway; flange‑mount IM‑B5 installation structure; internal pre‑sealed bearing chambers; no built‑in brake assembly; internal stator embedded PTC thermal‑protection sensor; rotatable connector housing for flexible cable routing directionKollmorgen.
Working Principle: Three‑phase sinusoidal current output from matched servo drive generates rotating magnetic‑field inside stator assembly. Permanent‑magnet rotor follows magnetic‑field rotation and outputs precise mechanical torque. Rear‑mounted resolver converts rotor real‑time angle and velocity into analog sine‑cosine feedback signals and transmits back to servo drive. Servo drive completes electronic commutation and closed‑loop torque‑velocity‑position control according to resolver feedback data. PTC sensor monitors winding temperature continuously and outputs over‑temperature alarm signal upon over‑heat occurrenceKollmorgen.
Installation Requirements: Rigidly mount via IM‑B5 front‑flange surface; guarantee mounting‑surface flatness less than 0.1 mm; maintain shaft‑to‑load coupling coaxiality error below 0.1 mm; reserve minimum 50 mm free‑space behind motor housing for heat dissipation; motor protective‑earth terminal must connect reliably to cabinet grounding bar; use shielded dedicated motor‑feedback hybrid cables; avoid installation adjacent to high‑heat radiation sources; strictly prohibit direct hard‑hammer striking on motor output‑shaft end‑face.
Usage Notes: Never connect motor windings directly to AC mains power supply; do not exceed maximum mechanical rotation‑speed rating; avoid excessive radial‑axial load acting on motor shaft beyond specification; PTC thermal‑sensor signal must be connected and evaluated by servo drive system; keep connector sealing‑gasket intact to guarantee IP65 protection performance; spare‑part replacement must verify winding parameters and resolver wiring definition consistency; solvent‑based chemical agents shall not contact motor painted housing surfaceKollmorgen
