The Omron R88M-K4K030H-B is an AC servo motor engineered to provide reliable performance in industrial applications. Rated at 230 volts, this motor can generate a power output of 4 kW. For accurate motion feedback, it utilizes a 20-bit incremental encoder, enabling precise control during operation.

The motor operates at a nominal speed of 3000 RPM and can peak at 4500 RPM for demanding tasks that require rapid movement. Its continuous current rating is recorded at 19.6 amperes, while peak current handling can reach 83 amperes. This servo motor is capable of producing a torque of 12.7 Newton-meters, with an overload torque rating of 38.2 Newton-meters, maintaining functionality in high-stress scenarios.

In terms of mechanical characteristics, the rotor has a mass moment of inertia measuring 14.2 × 10⁻⁴ kg·m². It is compatible with a variety of loads, handling up to 15 times its rotor inertia, making it versatile for different applications. The integrated brake requires a voltage input of 24 VDC with a tolerance of ± 10 percent and consumes 22 watts of energy during operation. The total weight of the motor, including the brake unit, is approximately 12.6 kilograms.
