Description

ELAU 140‑30‑210‑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 (155 °C), protection class IP65 at shaft‑end, natural self‑cooling, B5 140 mm mounting flange, 19 mm flat‑key shaft, incremental Sin‑Cos S1 encoder, P1‑type power connector, no built‑in holding brake, total weight 14.2 kg, operating ambient temperature 0 °C‑40 °C.

Functional Features: Incremental Sin‑Cos S1 encoder provides high‑quality analog differential feedback signals for high‑precision motion‑loop calculation. Built‑in electronic nameplate supports one‑click automatic motor‑parameter reading by PacDrive MC‑4 and SX‑series servo drives. Medium‑inertia rotor achieves fast acceleration‑deceleration response while bearing large‑amplitude load torque variation. Internal stator‑embedded PTC thermal‑sensor triggers hardware‑level over‑temperature protection. Optimized sinusoidal back‑EMF design lowers power loss of long‑distance motor cables. Fully‑sealed bearing assembly realizes maintenance‑free long‑term continuous operation.

Application Scenarios: Packaging machinery main drive axes, printing‑press auxiliary motion‑control units, automated gantry material‑handling systems, plastic‑processing production‑line servo‑driving mechanisms, multi‑axis special‑purpose processing equipment.

Performance Parameters: 128 sine‑cosine periods per encoder revolution, CE and UL industrial compliance certification, three‑phase 400‑480 V AC power supply.

Material Composition: High‑strength die‑cast aluminum alloy motor housing, stacked silicon‑steel‑sheet stator core, neodymium‑iron‑boron rare‑earth permanent‑magnet rotor, oxygen‑free copper winding wires, quenched alloy‑steel output shaft, reinforced thermoplastic power and signal connector housings.

Structural Features: Standard IM B5 front‑flange mounting structure. Independent P1 power connector and Sin‑Cos encoder signal connector locate on upper motor housing surface. Shaft‑end integrated labyrinth sealing assembly guarantees IP65 dust‑proof and splash‑water‑resistant performance. PTC thermal‑sensing elements embed inside stator winding coils. Reinforced mechanical‑structure rotor‑shaft improves anti‑vibration capability under cyclic load impact.

Working Principle: Servo drive outputs three‑phase sinusoidal excitation current into stator windings and generates rotating magnetic field. Interaction between stator rotating magnetic field and rotor permanent‑magnet field produces driving output torque. Incremental Sin‑Cos encoder converts rotor mechanical angle and rotation speed into differential analog feedback signals and transmits to servo drive, so that closed‑loop position‑speed‑torque motion‑control loop completes.

Installation Requirements: Fasten motor flange to rigid low‑vibration metal mounting base. Control coupling concentricity error within 0.05 mm tolerance. Reserve sufficient surrounding ventilation clearance for natural‑convection heat dissipation. Separate power‑cable routing and encoder‑feedback‑cable routing paths. Reliably connect motor protective‑earth terminal to cabinet ground busbar. Check full‑connector‑locking condition after wiring completion.

Usage Notes: Keep operating‑environment non‑condensing with relative humidity 5‑85 %. Do not exceed allowable radial and axial shaft‑load values defined in specification document. Configure servo‑drive feedback‑parameter for incremental Sin‑Cos encoder working mode. Avoid sustained peak‑torque running‑status for long duration. Prevent mechanical impact and welding‑current damage to motor housing shell.
