Omron's model R88M-K4K020T-OS2 is an AC servomotor engineered for high-performance applications. When not equipped with a brake, it weighs about 15.5 kilograms and operates on a nominal voltage of 200 V. This unit features a 17-bit absolute encoder, enabling precise position feedback essential for accurate control.

Individuals using this motor can expect a remarkable power rate of 97.1 kW/s without the brake engaged. The motor achieves a rated rotational speed of 2000 RPM, while its maximum speed reaches 3000 RPM. Torque ratings are also notable, showcasing a rated torque of 19.1 N·m and a peak torque reaching 57.3 N·m.

The mechanical design supports significant loads, with allowable radial and axial loads rated at 784 N and 343 N, respectively. The motor includes an oil seal to protect against contaminants to ensure reliable operation. The rated electrical current for this servomotor is 21.0 A, while the peak current can surge to 89 A, allowing for robust performance under varying conditions.

The motor's rotor has a moment of inertia of 37.6×10⁻⁴ kg·m², providing it with the necessary stability during operation. Additionally, it can accommodate load inertia ratios up to ten times its rotor inertia, making it versatile for various applications. Time constants are 0.65 ms for mechanical response and 20 ms for electrical adjustment, allowing quick response times in highly dynamic environments. Overall, the R88M-K4K020T-OS2 is tailored for users seeking reliability and performance in their servo motor applications.
