Material Composition: Cast aluminum alloy motor housing Neodymium iron boron permanent magnet rotor core F-class insulated copper stator winding Alloy steel solid output shaft Precision sealed ball bearings Rubber sealing gaskets for flange and rear end cover Metal terminals inside KK quick connector
Structural Characteristics: Small cylindrical compact motor body Front mounting flange integrated with the housing Solid smooth output shaft Rear end assembled with encoder module KK combined quick connector mounted on motor side wall, integrating power circuit and encoder signal circuit TF temperature sensing element embedded inside stator winding
Working Principle: MOVIDRIVE servo inverter outputs three-phase sinusoidal current to the stator winding. Alternating magnetic field generated by stator interacts with permanent magnet on rotor to produce electromagnetic torque and drive motor rotation. RH1M incremental encoder collects rotor speed and relative position information, converts physical rotation into pulse signals and transmits feedback data back to servo drive. TF thermal contact detects real-time winding temperature, outputs switching alarm signal once temperature exceeds preset threshold. KK connector transmits power supply and feedback signals between motor and servo drive.
Installation Requirements: Rigidly fasten motor flange onto mechanical equipment frame Ensure high coaxiality between motor shaft and driven load to eliminate radial and axial offset Installation environment must avoid continuous liquid splash, heavy dust and corrosive gas Use SEW designated shielded power cable and shielded encoder cable Lock KK quick connector completely after cable connection
Precautions for Use: Avoid heavy mechanical impact to motor shaft and encoder housing during transportation and installation Do not continuously operate motor under peak overload torque Maintain integrity of rubber sealing gaskets to keep IP65 protection performance Do not disassemble encoder module without professional maintenance personnel Check wiring tightness of KK connector regularly during long-time operation
