The Omron R88M-K4K020F-B servo motor exemplifies precision engineering tailored for robust applications. It operates using an incremental encoder with a high resolution of 20 bits, which contributes to its pinpoint accuracy in motion control. Designed for demanding use, this motor can handle radial loads of up to 490 N and thrust loads of 196 N, making it suitable for various industrial tasks.
The motor exhibits a rated torque of 19.1 N·m, with the capability to reach a peak torque of 57.3 N·m. With an output power of 4 kW, it delivers excellent performance across different operational requirements. It is capable of achieving a rated speed of 2000 rpm, with a maximum speed threshold of 3000 rpm, allowing for efficient motion response in dynamic environments.
Constructed with a significant load inertia, which is ten times that of the rotor inertia, this motor can efficiently manage operational stresses. The rotor inertia stands at 38.6 × 10⁻⁴ kg·m², providing a solid performance foundation. The motor also has a mass of 18.7 kg when fitted with the brake, reflecting its durable design.
Thermal management is assured through its Class F insulation, while self-cooling allows for consistent operation under a variety of conditions. The R88M-K4K020F-B is securely housed in an IP67-rated enclosure, meaning it is fully sealed against dust and can withstand moisture, making it suitable for harsh industrial settings.
