The Omron R88M-K3K030F-S2 is a 3 kW cylindrical servo motor from the Accurax G5 series, rated for 3000 rpm on a 3-phase 480 VAC supply. It carries an incremental encoder and a key-and-tap shaft, with no brake fitted — meaning the load must be held by the drive's holding brake or an external mechanical brake when power is removed. The compact cylindrical body and smart-connector interface (per the series description) simplify cabling in tight panel layouts.
The 3 kW / 3000 rpm rating sizes this motor for medium-torque applications like conveyors, spindle drives, or indexing tables running on a 480 VAC three-phase line. The incremental encoder (typically 20-bit or 17-bit on G5 motors) provides position feedback for standard motion control but does not retain position after a power cycle — the drive must re-home on startup. No brake means the motor rotor freewheels when power drops; if vertical-axis holding is required, the drive's dynamic brake resistor or an external spring-set brake must be added. The cylindrical shape with keyed shaft fits standard metric couplings and pulleys; the key-and-tap feature allows positive shaft locking without setscrew slippage.
