Description
ELAU 140‑210‑P1‑45‑S1‑B0
Technical Specifications: Rated power 4.05 kW, rated speed 3000 rpm, maximum mechanical speed 4500 rpm, continuous stall torque 21 Nm, peak torque 58.8 Nm, rotor inertia 10.9 kg·cm², insulation class F, shaft‑end IP65 protection rating, natural self‑cooling, B5 140 mm mounting flange, 19 mm flat‑key shaft, incremental Sin‑Cos S1 encoder feedback, P1 power connector, B0 no‑brake configuration, net weight 14.2 kg, operating ambient temperature 0 °C‑40 °C.
Functional Features: Incremental Sin‑Cos S1 encoder delivers high‑resolution speed and position feedback signal. Electronic nameplate inside encoder allows automatic motor‑parameter identification by PacDrive servo controllers. Medium‑inertia rotor balances dynamic response and heavy‑load driving capability. Built‑in PTC thermal sensor implements winding over‑temperature protection. High sine‑wave back‑EMF characteristic reduces cable copper power consumption. Sealed maintenance‑free bearing unit extends whole‑service‑life cycle.
Application Scenarios: Medium‑load packaging production‑line main and auxiliary axes, printing equipment motion drive units, automated material‑handling gantry mechanisms, rubber‑plastic processing auxiliary drive equipment, general‑purpose multi‑axis processing machinery.
Performance Parameters: Sin‑Cos encoder 128 sine‑cosine periods per revolution, CE and UL certification, three‑phase 400‑480 V AC power input.
Material Composition: Die‑cast high‑strength aluminum alloy motor housing, laminated silicon‑steel‑sheet stator core, neodymium‑iron‑boron permanent‑magnet rotor, oxygen‑free copper stator winding conductors, quenched alloy‑steel output shaft, reinforced thermoplastic connector outer shells.
Structural Features: Standard B5 front‑flange mounting layout. Separated P1 power connector and Sin‑Cos encoder signal connector mount on top housing surface. Shaft‑end labyrinth‑type sealing assembly ensures IP65 dust‑proof and splash‑water‑resistant performance. PTC thermal sensing components embed within stator winding structure. Compact rectangular frame layout optimizes mechanical installation space arrangement.
Working Principle: Three‑phase sinusoidal current output from servo drive creates stator rotating magnetic field. Magnetic‑field coupling between stator and rotor permanent magnet generates driving output torque. Incremental Sin‑Cos encoder delivers real‑time rotor position and speed analog signals back to servo drive to complete closed‑loop position, speed and torque regulation.
Installation Requirements: Mount motor onto sufficiently rigid low‑vibration metal base. Guarantee coupling concentricity deviation below 0.05 mm. Maintain adequate surrounding ventilation space for heat dissipation. Route power cables and encoder signal cables inside separated cable ducts. Complete reliable protective‑earth connection for motor housing. Inspect connector locking state after wiring work finishes.
Usage Notes: Ambient relative humidity must keep in 5‑85 % non‑condensing scope. Do not subject motor shaft to radial and axial overload exceeding technical‑specification limits. Set servo‑drive feedback‑parameter to incremental Sin‑Cos encoder mode. Prohibit continuous long‑time peak‑torque operation. Prevent welding current flowing through motor housing shell.
