R88M-K1K530C-BS2 — Accurax G5 servo motor, 1.5 kW, with brake
The Omron R88M-K1K530C-BS2 is a cylindrical-frame servo motor from the Accurax G5 series, rated for 1.5 kW continuous output at 3000 rpm on a 3-phase 480 VAC supply. It carries an integral holding brake and an absolute encoder, making it a fit for vertical-axis or high-hold applications where position must be retained at power-off.
What the ratings mean for fit
The 1.5 kW capacity at 3000 rpm defines the continuous mechanical output — sized for a load requiring that torque-speed envelope, such as a small conveyor, indexing table, or spindle drive. The 480 VAC 3-phase supply is common in North American industrial panels; verify the drive's input matches before wiring. The integral brake (Yes) means the motor can hold a vertical load without an external brake resistor or mechanical lock — critical for Z-axis or gravity-loaded axes. The absolute encoder eliminates the need for a home-search sequence on power-up, reducing cycle time in multi-axis systems.
Deployment context
Cylindrical frame with key and tap — mounts via a standard flange pattern, typically coupled to a ball screw or timing-belt drive. The Accurax G5 series uses smart connectors for power and encoder feedback, which simplifies cable replacement in the field. No oil-tight seal is listed, so this motor is not rated for washdown or coolant splash; keep it in a dry, enclosed cabinet or guarded area.
