OMRON R88M‑K2K030C‑BS2

Product Brief: R88M‑K2K030C‑BS2 is OMRON G5‑series 2000 W AC servo motor with electromagnetic holding brake, matched with R88D‑KN20H‑ECT EtherCAT servo driveOMRON Indu…. This motor equips with high‑resolution absolute encoder and built‑in 24 VDC power‑off activated holding brake. The brake provides static holding torque for vertical axis when power supply cuts off, prevents load free‑fall risk. High torque density and fast dynamic response adapt to heavy‑load high‑precision automation equipment vertical‑axis and inclined‑axis motion control scenarios.

Functional Features: Built‑in power‑off electromagnetic holding brake guarantees load static position retention for vertical axes; high peak‑torque output realizes heavy‑load fast acceleration‑deceleration; low‑cogging rotor design reduces low‑speed torque ripple; high‑resolution absolute encoder supports power‑on position reading without homing operation; 130‑mm standard flange structure for mechanical installation; compatible with G5‑series EtherCAT servo drive system.

Application Scenarios: Vertical lifting axis of automated machinery; gantry‑type robot Z‑axis driving; heavy‑load packaging equipment; large‑scale material handling mechanism; 2000‑W brake‑type servo system spare‑part replacement.

Performance Parameters: Class‑F insulation ensures winding thermal safety under long‑time heavy‑load operation; vibration and shock resistance meet industrial servo motor IEC standards; maximum allowable load inertia reaches 10 times rotor inertia; brake mechanical service life satisfies minimum 10 million holding‑release cycles.

Material Composition: Thick‑wall aluminum‑alloy 130‑mm mounting flange; cast‑aluminum motor housing; silicon‑steel‑sheet laminated stator core; high‑energy‑density permanent‑magnet rotor assembly; high‑precision heavy‑duty ball bearing groups; built‑in electromagnetic brake assembly; high‑resolution absolute encoder unit; metal‑shell power, brake and encoder connectors; key‑groove processed output shaft.

Structural Features: 130‑mm square standard flange mounting structure; output shaft equipped with standard keyway for torque transmission; internal electromagnetic brake assembly located between rotor and encoder; rear‑side multi‑group metal‑shell connectors for power, brake coil and encoder signal; robust cylindrical housing; shaft‑end sealing ring realizes dust‑proof and splash‑water‑proof performance.

Working Principle: Matched servo drive outputs three‑phase alternating current to motor stator windings to generate rotating magnetic field, interacts with rotor permanent magnet to produce driving torque for shaft rotation. Built‑in electromagnetic brake coil energizes under DC24 V power condition to release brake friction disc and allow motor free rotation. When brake power supply cuts off, spring mechanism pushes friction disc to lock rotor shaft and output shaft for static holding. Absolute encoder collects real‑time shaft position data and feeds back to servo drive to form closed‑loop motion control.

Installation Requirements: Secure motor flange onto mechanical mounting surface using high‑strength bolts with specified tightening torque; select heavy‑duty coupling matched with 24 mm key‑way shaft; adopt dedicated shielded servo power cable, brake cable and encoder feedback cable; separate servo signal cables from high‑power inverter power cables; correctly connect DC24 V brake coil power circuit according to wiring diagram; protect shaft‑end sealing ring from scratch during installation.

Usage Notes: Electromagnetic holding brake only undertakes static holding function, cannot serve as dynamic braking device during high‑speed rotation; do not exceed rated continuous torque and momentary peak‑torque limits; connector area maintains IP20 protection grade, avoid liquid and dust intrusion; do not deploy in environments with corrosive gas; regularly inspect cable connection tightness and brake wiring condition.
