Material Composition: Thickened die‑cast aluminum alloy fin‑cooled housing, thick stacked silicon‑steel sheet stator core, large‑size high‑energy neodymium‑iron‑boron permanent magnet rotor, high‑strength quenched alloy steel output shaft, glass‑fiber‑reinforced flame‑retardant PA plastic large‑current connector shell.
Structural Characteristics: Fully‑enclosed heavy‑duty fin‑cooled housing, IM B5 flange‑mount installation structure, keyway‑equipped large‑diameter output shaft, side‑mounted 55‑degree rotatable large‑current M23 power and feedback dual‑connectors, PT100 thermal sensing element embedded inside stator winding, non‑brake mechanical structure, multi‑layer heavy‑duty dust‑proof and oil‑proof sealing design.
Working Principle: Three‑phase sinusoidal alternating‑current inputs stator windings to generate rotating magnetic‑field, driving large‑size permanent‑magnet rotor synchronous rotation. Multi‑turn Hiperface absolute encoder collects rotor absolute angle and rotating‑speed data and transmits feedback signal to matched high‑current servo drive. Servo drive completes cascade closed‑loop control of current, speed and position to realize heavy‑load precise motion output. Embedded thermal sensor uploads winding temperature data continuously for over‑temperature protection.
Installation Requirements: Use high‑strength metric bolts with specified torque to fasten motor flange to mechanical mounting surface; coupling coaxial alignment tolerance must keep below 0.05 mm; maintain minimum 80 mm surrounding clearance for housing heat dissipation; install inside cabinet or enclosed mechanical space; lock large‑current connector locking ring completely to prevent loosening under heavy‑load vibration; strictly separate high‑power motor cable and feedback signal‑cable routing paths.
Usage Notes: Avoid heavy impact collision on motor shaft during hoisting and installation; encoder type and motor parameter dataset must match supporting high‑current servo drive; prohibit long‑time continuous operation under peak‑torque state; prevent oil mist, conductive dust and liquid from breaking through IP65 sealing surface; strictly implement ESD anti‑static protection when maintaining encoder wiring terminals; regularly check large‑current connector tightening torque under heavy‑vibration working environment.
