Product Description:
Bosch Rexroth produces the AC servo motor 2AD134D-B35LL1-CS26-C2N1 with a frame size of 134 mm and length D. It comes with the mounting options of both flanges and feet configuration. This motor offers a power terminal that is located on the left side of body frame and its housing is rated as IP64 to safeguard from external intrudes.
The 2AD134D-B35LL1-CS26-C2N1 servo motor consumes a rated power of 26000 W when it operates in nominal condition and delivers a turn effect of 166 Nm. Its nominal operating speed is 1500 rev/minute but the peak speed it can offer is 7500 rev/minute. The 2AD servo motor needs a nominal voltage of 387 Veff and draws a continuous current of 52 A. It has an angular moment of inertial 0.118 kgm² and a time constant is 0.9 h to drop the temperature by half from the present value. The motor uses an axial blower which sends air from side B to A at an average air volume of approx. 588.58 CFM and it consumes 136 W of power while operating on 3 x 400 V or 3 x 460 V at 50Hz/60Hz frequency. The 2AD servo motor comes with a plain shaft that has an imposed sealing ring on it, to make the motor an overall IP65 protected from dust and water splashes.
The 2AD134D-B35LL1-CS26-C2N1 AC servo motor features a digital servo feedback system for motion control. It employs common industrial bearings and meets the vibration standard R. The recommended thickness of a power cable is 10 mm² for electrical connections to the left sided junction box. Customers can order this 2AD motor directly from Wake Industrial.
Frequently Asked Questions about 2AD134D-B35LL1-CS26-C2N1:
Q: Why does the 2AD134D-B35LL1-CS26-C2N1 use a digital feedback system?
A: The digital servo feedback ensures real-time motion accuracy and seamless integration with drive controllers. It enhances response time and reduces positioning errors.
Q: How does the axial blower configuration (B to A) benefit this motor?
A: Airflow from side B to A maintains uniform cooling, reducing thermal stress. It supports extended runtime at high load without overheating.
Q: Why is an IP65 sealing ring important on the plain shaft of 2AD134D-B35LL1-CS26-C2N1?
A: It prevents dust ingress and water splash damage at the most exposed part—the shaft. This protection extends motor life in harsh environments.
Q: What is the significance of the 0.9 h thermal time constant?
A: A longer time constant means the motor retains heat longer, stabilizing thermal fluctuations. This helps maintain consistent performance in varying duty cycles.
Q: What role does the 0.118 kg·m² moment of inertia play in motor performance?
A: This inertia value supports stable acceleration and deceleration under load. It helps prevent mechanical shock during fast changes in speed.
