Structural Characteristics: Small cylindrical compact body Front SB1 mounting flange Smooth solid output shaft Rear side encoder and brake assembly KY combined quick connector integrates power line and encoder signal line Built‑in winding temperature monitoring element
Working Principle: Servo inverter outputs three‑phase current into stator winding. Stator alternating magnetic field interacts with rotor permanent magnet to produce electromagnetic torque and rotate motor. RH1M incremental encoder generates pulse signal reflecting rotor speed and relative position and transmits feedback signal to servo drive. Holding brake locks shaft once brake coil power is cut off to prevent load falling or shifting. Winding temperature sensor monitors motor temperature during continuous operation.
Installation Requirements: Rigidly fix motor flange to machine structure Guarantee coaxial alignment between motor shaft and load to reduce radial stress Installation environment avoids liquid splash, heavy dust and corrosive gas Use SEW specified shielded power cable and encoder cable Tighten KY quick connector completely
Precautions for Use: Avoid mechanical impact to shaft and encoder housing during transportation and installation Verify brake release function before commissioning Sustained operation above peak torque is forbidden Preserve sealing gaskets to keep IP65 protection level Disassembly of encoder and brake must be completed by professional technicians
