Model R88M-K3K020F-B, produced by Omron, is a well-engineered AC servo motor tailored for high-demand industrial applications. It offers a strong rated output of 3,000 W, making it suitable for tasks that require both reliability and power. The motor is designed to operate at a voltage of 400 V and achieves a maximum speed of 3,000 rpm, with a standard rating at 2,000 rpm.

In terms of performance, the torque provided by this model is rated at 14.3 N·m while the peak torque can reach up to 43.0 N·m. Load capacities are significant, supporting 784 N in radial loads and 343 N in thrust conditions. Weighing approximately 12.6 kg with brake included, the motor remains relatively lightweight within its class for easy handling.

This servo motor utilizes a 20-bit incremental encoder, which ensures accurate feedback for precise motion control. The power rate with the brake is 144 kW/s, enhancing its ability to manage dynamic loads. It possesses an inertia moment of 14.2×10⁻⁴ kg·m² and can handle maximum load inertia up to ten times the rotor inertia, demonstrating its adaptability to various operational demands.

Time constant specifications show a mechanical response of 0.61 ms and an electrical response of 12 ms, indicating how quickly the motor responds to control signals. A rated current of 8.7 A (RMS) further illustrates its efficiency in power management. This combination of specifications makes the R88M-K3K020F-B suitable for a range of high-performance applications in automation and robotics.
