The Omron R88M-K40030S-OS2 is a reliable AC servomotor, providing a competitive power output of 400 watts. Its rotor inertia measures at 0.26 × 10⁻⁴ kg·m², which denotes the motor's responsiveness within systems. This motor can handle load inertia up to 30 times the rotor inertia, making it adaptable for heavier applications.
In terms of performance, the unit offers a rated torque of 1.3 N·m and is designed to operate at a standard speed of 3,000 r/min. It can achieve maximum speeds of 6,000 r/min for tasks requiring higher output. The torque constant is set at 0.21 N·m/A ±10%, which is beneficial in maintaining consistency in torque production.
The power rate is also recorded at 62.3 kW/s without the brake, enabling swift adjustments to operating conditions. Mechanical time constants are noted at 0.48 ms, and electrical time constants at 3.4 ms, ensuring fast response times. Current ratings are specified with a rated value of 4.6 A, escalating to a maximum of 19.5 A under peak conditions.
Load capacities allow for 245 N radially and 98 N in thrust applications. The shaft is straight, keyed, and tapped, adhering to standard design. An oil seal is included to protect internal components from contamination. This motor weighs approximately 1.2 kg when the brake is not included, maintaining a lightweight profile suitable for various setups.
