Product Description:
Sanyo Denki is a reliable industrial automation products manufacturer and the R2AA13120LCP2E servo motor is one of their products. The servo motor is mainly required in Industrial automation applications for its diverse range of functions.
The R2AA13120LCP2E Servo Motor generates 26.2 mV per unit of speed. The maximum current it can tolerate without immediate damage is 25.6 arms. It features an optical battery backup absolute encoder which is able to provide precise position feedback with absolute positioning and battery retention even without power. For operating the brake it needs 0.17 amperes current. It has the rated output ability of 1.2 kW which it can sustain efficiently. The module encoder provides high positional resolution (131072 positions per revolution) for accurate motion control. It has an electrical time constant value of 2.4 ms. For operating the electromagnetics holding brake it requires input voltage range from DC90 Volts / DC24V with 10% tolerance. The module adheres to European and North American safety and quality standards. It needs 9.1 arms current to maintain rated stall torque continuously without thermal damage. It comes with 0.27 ohms phase resistance which is used to calculate power losses and temperature rise.
The R SANMOTION series module is suitable for harsh environments as it is dust tight and protected against water jets. It can increase its output power with 54 k watts per seconds. Its position information is digitally transmitted over the serial interface which reduces wiring complexity. The inertia of its rotor alone is 6.1 ×10⁻⁴ kgm² which is critical for tuning acceleration and deceleration profiles. This module has a peak stall torque value of 16 newton meters. The minimum holding torque provided by its brake to resist movement when powered off is 9.0 Nm.
Frequently Asked Questions about R2AA13120LCP2E:
Q: Why does the R2AA13120LCP2E motor use a 17-bit encoder resolution?
A: The high 17-bit resolution enables ultra-precise position control for demanding motion tasks. This ensures reduced drift and enhanced feedback accuracy in closed-loop systems.
Q: How does the torque constant of 0.77 N·m/Arms benefit the motor's performance?
A: A higher torque constant like 0.77 N·m/Arms means more torque per ampere, improving energy efficiency. It enhances motor responsiveness under varying loads.
Q: What is the function of the 2.8 kVA amplifier capacity in R2AA13120LCP2E?
A: The 2.8 kVA capacity ensures the amplifier can handle peak load demands without fault. This supports stable and continuous power delivery in fast dynamic applications.
Q: How does the medium inertia class of R2AA13120LCP2E affect application use?
A: Medium inertia balances high-speed capability with stability, making it ideal for general-purpose industrial tasks. It minimizes overshoot while maintaining motion smoothness.
Q: Why is the rotor inertia of 6.1 ×10⁻⁴ kg·m² important in this motor?
A: It affects acceleration and deceleration performance during start-stop cycles. The specified value ensures optimized control for medium-speed operations.
