Overview
The ECOSTEP 34T503-0700 is a high-performance rotary servo motor in the ECOSTEP 34T50x series, engineered for demanding industrial applications requiring precision and power in a standard NEMA 34 (86 mm) flange. With a motor length of 190 mm, a 14 mm shaft, and a mass of 5.7 kg, it combines a compact form factor with substantial power delivery.
Operating at a 325 V DC link, the motor delivers 2.69 Nm rated torque at 500 min⁻¹ and up to 10 Nm peak torque. It supports speeds up to 3000 min⁻¹, making it a versatile solution for high-throughput motion tasks. The motor features IP40 protection as standard, with an optional IP65 upgrade (shaft gland remains IP40) for harsh environments. It is designed for optimal performance when paired with the ECOVARIO 414 servo amplifier.
Advantages
The ECOSTEP 34T503-0700 delivers high-torque servo performance for heavy-duty automation in space-constrained environments.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- Compact and Powerful: Exceptionally high maximum torque relative to the NEMA 34 size allows for the design of smaller, more efficient machinery without compromising performance.
- Direct Drive Capability: High torque output often eliminates the need for a gearbox. This reduces system complexity, lowers costs, and removes sources of backlash and maintenance.
- High Dynamic Performance: Genuine servo operation provides the rapid acceleration and precise control necessary for high-throughput dynamic applications.
- Extensive Adaptation: Mechanical and electrical customization options, including shaft/flange types and winding adaptations, ensure the motor meets specific operating points.
- Economical Solution: Offers an excellent price-to-performance ratio compared to conventional AC servo motors.
Where it fits
Use this high-torque NEMA 34 servo motor for industrial automation tasks requiring robust power and precise control.
- Direct-drive rotary axes in packaging machinery (labeling, sealing, cutting) where reduced backlash improves accuracy.
- Material handling and pick-and-place systems requiring rapid acceleration cycles to increase throughput.
- Test and measurement equipment where the compact NEMA 34 frame and precise control are critical.
- Vertical axes utilizing the optional holding brake for safety and load holding.
