R88M-K4K020H-B

The Omron R88M-K4K020H-B AC servo motor is engineered for high-performance tasks in automated environments. With a standard operating voltage of 230 V, it supplies nominal power of 4,000 W. The motor's nominal torque is measured at 19.1 N·m, supporting the precision needed in various applications. Operating at a nominal rotational speed of 2,000 revolutions per minute and capable of reaching a peak speed of 3,000 revolutions per minute, this unit is designed for dynamic performance.

This servo motor accommodates a significant instantaneous peak torque of 57.3 N·m, enhancing its capability to handle sudden load variations and acceleration demands. The rotor inertia, measured at 38.6 × 10⁻⁴ kg·m², ensures stability during operation. It operates with a nominal current of 21.0 A (rms) and can draw an instantaneous peak current of 89 A (rms) under specific conditions.

In terms of mechanics, the total weight of the motor, including the brake, is about 18.7 kg. An aluminum radiator plate with dimensions of 470 × 440 × t30 is used for effective heat dissipation. The brake function relies on an excitation voltage of 24 VDC ± 10%, producing a minimum static friction torque of 24.5 N·m. This thoughtful engineering makes the R88M-K4K020H-B a robust choice for applications that demand reliable torque and speed control.
