Material & Structural Features:
-
Magnet Material: Rare-earth permanent magnets for high torque density.
-
Insulation Class: Class H (high thermal endurance).
-
Feedback: Pre-assembled resolver (standard), optional encoder adapter.
-
Shaft: Open keyway shaft with rear shaft extension; optional FKM fluoroelastomer shaft seal.
