Description
REXROTH MSK040C-0600-NN-M1-UG0-NNNN
Technical Specifications Frame size MSK040, length class C; rated speed 6000 rpm; permanent magnet synchronous structure; multi-turn absolute encoder feedback; built-in electromagnetic holding brake; 400V three-phase winding; smooth plain output shaft; flange mounting; IP65 protection rating; natural convection cooling.
Functional Features High torque density compact mechanical design; low rotor inertia for fast dynamic response; integrated holding brake for static shaft locking in power loss condition; absolute encoder retains position data after power cut; low cogging torque guarantees smooth low-speed operation; high short-time overload capability.
Application Scenarios Packaging machine main servo axis; converting and slitting equipment; automated gantry small axis; textile machinery traverse drive; rotary indexing table positioning.
Performance Parameters Operating ambient temperature -20℃ to +40℃; storage temperature -40℃ to +85℃; relative humidity 5% to 90%, no condensation; insulation class F; IP65 protection against dust and splash water.
Material Composition Aluminum alloy motor housing; laminated silicon steel stator core; rare-earth permanent magnet rotor; insulated copper stator winding; stainless steel smooth output shaft; polyurethane shaft lip sealing ring; metal absolute encoder assembly; electromagnetic brake friction disc and coil assembly.
Structural Characteristics Cylindrical motor body with standard front mounting flange; rear side absolute encoder assembly; internal electromagnetic brake chamber; side connector box for power and encoder wiring; shaft lip seal installed at shaft outlet for environmental sealing.
Working Principle Three-phase variable frequency AC current from Rexroth servo drive excites stator winding and generates rotating magnetic field, driving permanent magnet rotor to rotate and output mechanical torque. Absolute encoder detects rotor angle and speed continuously and sends feedback signal back to servo drive for closed-loop control. When power supply cuts off, brake engages and locks output shaft to prevent shaft rotation.
Installation Requirements Fix motor flange rigidly on machine frame. Use shielded power cable and encoder cable, separate power wiring from low signal wiring. Align coupling carefully to avoid shaft misalignment. Complete protective earthing of motor housing. Execute motor parameter identification in IndraDrive drive and test brake operation.
Usage Notes Do not manually force shaft rotation while brake engaged. Keep ventilation around motor housing for heat dissipation. Check shaft sealing ring regularly for dust and moisture ingress. Do not disassemble encoder module without professional maintenance tools.
