Overview
The ECOSTEP 34T532-0400 is a versatile, high-performance servo motor in the ECOSTEP 34T53x series, engineered for demanding motion control applications on 325 V DC systems. This model distinguishes itself from lower-voltage variants by enabling higher power output in the same standard NEMA 34 (86 mm) flange.
Operating at a 325 V DC link, the motor delivers 4.7 Nm rated torque at 500 min⁻¹ and 245 W rated power, with a peak torque of 6.13 Nm. It supports speeds up to 3000 min⁻¹, making it ideal for applications requiring both high torque density and rapid dynamics. Standard protection is IP40, with an optional IP65 upgrade available (shaft gland remains IP40). The motor is optimized for seamless integration with ECOVARIO 414 and ECOVARIO 415D servo amplifiers.
Advantages
The ECOSTEP 34T532-0400 combines power, precision, and customization to deliver optimal performance in a compact package.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- Power based on torque: Delivers very high maximum torque relative to its physical size, allowing for powerful acceleration in space-constrained applications.
- Direct Drive: High torque output often allows the motor to connect directly to the load. This can save the cost, complexity, and mechanical losses associated with a gearbox.
- High Dynamic Performance: True servo operation enables exceptional responsiveness, critical for rapid start-stop cycles or precise path following.
- Economical: Provides an excellent price-to-performance ratio compared to traditional AC servo motors, delivering high-end capabilities in a cost-effective solution.
- Electrical Adaptation: Motor windings can be adapted to customer-specific requirements to achieve the most efficient operating point for a given load profile.
Where it fits
Use this high-torque NEMA 34 servo motor for applications requiring robust power on 325 V DC systems.
- Dynamic axes requiring rapid start-stop cycles and precise positioning.
- Direct-drive applications where eliminating a gearbox reduces maintenance and backlash.
- Space-constrained machinery where high torque density allows for a smaller installation footprint.
- Through-shaft applications utilizing the optional hollow shaft with locking ring.
