Overview
The ECOSTEP 34T533-0400 is a high-performance rotary servo motor in the ECOSTEP 34T53x series, engineered for demanding automation applications on 325 V DC systems. It delivers exceptional torque relative to its compact NEMA 34 (86 mm) flange, making it a strategic choice for designing powerful systems within space-constrained environments.
Operating at a 325 V DC link, the motor provides 5.8 Nm rated torque at 500 min⁻¹ and 305 W rated power, with a peak torque of 9.14 Nm. It supports speeds up to 3000 min⁻¹, enabling rapid acceleration and smooth motion profiles. Standard protection is IP40, with an optional IP65 upgrade (shaft gland remains IP40). The motor is optimized for seamless integration with ECOVARIO 414 and ECOVARIO 415D servo amplifiers.
Advantages
The ECOSTEP 34T533-0400 combines high power density with the precision of genuine servo operation.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- High Torque Density: Delivers up to 9.14 Nm peak torque in a standard NEMA 34 frame, enabling machine miniaturization without sacrificing performance.
- Direct Drive Potential: High torque generation at low speeds often eliminates the need for mechanical gearboxes. This simplifies design, reduces system cost, and increases reliability.
- Dynamic Servo Performance: Provides highly dynamic control over speed and position, essential for applications requiring rapid start-stop cycles and accurate path following.
- Extensive Customization: Mechanical and electrical options, including shaft configurations and customer-specific windings, allow for seamless integration into specific application requirements.
- Economic Efficiency: Offers a strong price-to-performance ratio compared to traditional AC servo motors operating within a similar performance envelope.
