Material & Structure: Housing finished in dark industrial coating; rare-earth Neodymium Iron-Boron (NdFeB) interior permanent magnets; low-inertia rotor design.
-
Working Principle: Three-phase stator windings generate rotating magnetic field interacting with rotor magnets; resolver provides commutation and position signals to drive amplifier.
-
Installation Requirements: Mount via 4-hole flange (NEMA/IEC compatible); align shaft to avoid radial loads; use flexible couplings.
-
Usage Precautions: Do not exceed 45°C ambient; ensure resolver cable shielding is grounded; periodic check of brake (if fitted) and insulation resistance.
