Technical Specifications: Frame size 71S Permanent magnet synchronous servo motor No integrated holding brake AK1H high‑resolution absolute encoder SM1 mounting flange, smooth shaft Insulation class F Protection class IP65 Ambient operating temperature -20℃ to +40℃ Net weight 4.9kg
Functional Features: Medium frame design without built‑in brake, lower rotor inertia for faster dynamic response AK1H high‑resolution absolute encoder provides high precision absolute position signal, homing unnecessary after power reset KY combined quick connector simplifies wiring work IP65 housing protection for direct installation on mechanical equipment Low torque ripple for ultra‑smooth rotation Supports continuous high‑speed operation and frequent cyclic positioning
Application Scenarios: Printing machine main synchronous roller Textile high‑speed spindle Automated continuous conveying servo axis Laser cutting machine motion axis High‑speed packaging rotary table
Performance Parameters: High dynamic acceleration capability High‑resolution absolute position feedback Defined continuous torque and peak overload torque Wide adjustable speed range for continuous operation
Material Composition: Cast aluminum alloy motor housing Neodymium iron boron permanent magnet rotor F‑class insulated copper stator winding Alloy steel output shaft Precision ball bearing Rubber sealing gaskets Metal SM1 mounting flange
Structural Characteristics: Cylindrical motor body Front SM1 mounting flange Smooth solid output shaft Rear encoder housing without brake assembly KY combined quick connector integrating power cable and encoder signal cable Built‑in stator winding temperature monitoring sensor
Working Principle: Servo inverter provides three‑phase sinusoidal current to stator winding. Alternating magnetic field interacts with rotor permanent magnet to produce electromagnetic torque and rotate motor. AK1H high‑resolution absolute encoder continuously detects absolute rotor position and transmits feedback data to servo drive for closed‑loop position control. Winding temperature sensor monitors motor operating temperature and sends overheat alarm when temperature exceeds limit. External mechanical brake needs to be configured separately for load holding requirement.
Installation Requirements: Rigidly fix SM1 flange onto mechanical frame Ensure precise shaft alignment between motor and load to reduce radial and axial load Installation environment avoids continuous water spray, heavy dust and corrosive vapor Use SEW specified shielded power cable and encoder cable Tighten KY quick connector completely Install separate external brake if load holding function is required
Precautions for Use: Avoid mechanical impact to shaft and encoder housing during transportation and installation This model does not contain built‑in brake, add external holding brake for vertical or suspended load applications Do not continuously run at peak overload torque Keep rubber sealing rings intact to maintain IP65 protection level Encoder disassembly must be performed by professional technicians
