Description
ELAU SB070‑40‑10‑05‑11‑S‑01‑64‑EAKN
Technical Specifications: Rated power 0.42 kW, rated speed 4000 rpm, maximum mechanical speed 4800 rpm, continuous stall torque 1.0 Nm, peak torque 3.2 Nm, rotor inertia 0.45 kg·cm², insulation class F, IP64 protection grade, natural convection cooling, B5 70 mm mounting flange, 14 mm flat‑key shaft, Sin‑Cos encoder feedback, without built‑in holding brake, net weight 3.4 kg, ambient operating temperature 0 °C‑40 °C.
Functional Features: Low‑inertia rotor achieves rapid acceleration‑deceleration response for short‑stroke fast positioning movements. Sin‑Cos encoder delivers high‑resolution position and velocity feedback signal for PMC‑2 controller. Internal stator‑embedded PTC thermal‑sensor implements winding over‑temperature protection. Sinusoidal back‑EMF motor design reduces current ripple. Maintenance‑free bearing assembly supports long‑term continuous production‑site operation. Optimized electrical parameters realize perfect matching with PMC‑2 drive hardware characteristics.
Application Scenarios: Standalone positioning stations controlled by PMC‑2 controllers, small‑format packaging machinery, printing auxiliary‑axis positioning units, textile automation motion mechanisms, special‑purpose automated assembly equipment.
Performance Parameters: Sin‑Cos encoder 64 sine‑cosine periods per revolution, CE industrial compliance certification, three‑phase 400‑480 V AC power input.
Material Composition: Die‑cast aluminum alloy motor housing, stacked 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 housing parts.
Structural Features: B5 standard front‑flange mounting structure. Integrated terminal‑box layout for power and feedback signal connection on motor rear‑end housing. Shaft‑end sealing assembly realizes IP64 dust‑proof and splash‑water‑resistant capability. PTC thermal sensing elements embed inside stator winding coils. Compact overall dimension adapts installation space requirements of small‑size automation machines.
Working Principle: PMC‑2 servo controller outputs three‑phase sinusoidal current to motor stator windings to generate rotating magnetic field. Magnetic‑field coupling between stator rotating field and rotor permanent magnet produces output driving torque. Sin‑Cos encoder collects real‑time rotor position and speed data and transmits analog feedback signal back to PMC‑2 controller, so that closed‑loop positioning, speed and torque control completes.
Installation Requirements: Secure motor flange on rigid low‑vibration metal mounting base. Keep coupling concentricity deviation less than 0.04 mm. Reserve surrounding ventilation space for natural heat dissipation. Separate power‑cable routing and encoder‑feedback‑cable routing paths. Complete reliable protective‑earth connection for motor housing. Check terminal‑box connector locking condition after wiring work finishes.
Usage Notes: Operating‑environment must keep non‑condensing with relative humidity 5‑85 %. Do not apply shaft radial‑axial load beyond published specification limits. Configure PMC‑2 controller feedback‑parameter for Sin‑Cos encoder working mode. Avoid sustained peak‑torque running status. Prevent hammer‑striking mechanical impact on motor output shaft and housing shell.
