Overview
The ECOSTEP 34T502-0700 is a high-torque 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 150 mm, a 12 mm shaft, and a mass of 4.2 kg, it embodies the design principle of delivering high torque density in a compact form factor.
Operating at a 325 V DC link, the motor provides 2.8 Nm rated torque at 500 min⁻¹ and up to 6.80 Nm peak torque. It supports speeds up to 3000 min⁻¹, making it suitable for rapid acceleration and deceleration profiles. The motor features IP40 protection as standard, with an optional IP65 rating (shaft gland remains IP40) for harsher environments. It is designed for seamless integration with the ECOVARIO 414 servo amplifier.
Advantages
The ECOSTEP 34T502-0700 delivers high-performance motion control for space-constrained industrial machinery.
- 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: Excellent torque density relative to the NEMA 34 size reduces the overall machine footprint without compromising output.
- Direct Drive Capability: High torque output often eliminates the need for a gearbox. This simplifies machine design, lowers system costs, and removes sources of backlash and maintenance.
- Very High Dynamics: Genuine servo operation ensures exceptional dynamic response for applications like pick-and-place and automation requiring precise positioning.
- Electrical Adaptation: Motor windings can be adapted to meet customer-specific operating points, ensuring maximum efficiency for the intended application.
- Economical Solution: Offers a superior price-to-performance ratio at its operating point compared to conventional AC servo motors.
