Overview
The ECOSTEP 34T501-0700 is a compact rotary servo motor in the ECOSTEP 34T50x series. It combines a standard 86 mm NEMA 34 flange with genuine servo operation for dynamic positioning tasks on higher voltage DC links. With a motor length of approximately 112 mm and a mass of roughly 2.7 kg, it offers a high-performance alternative to typical stepper-based NEMA 34 axes in a similar footprint.
At a 325 V DC link, the 34T501-0700 provides up to 3.9 Nm peak torque and 1.87 Nm rated torque at 500 min⁻¹, with speeds up to 3000 min⁻¹. This performance supports direct drive concepts in many applications. Standard protection is IP40 with an IP65 option for more demanding environments (shaft gland remains IP40). The motor is UL certified and can be configured with a 5 Nm holding brake, different encoder systems, and mechanical options. It is optimized for use with the ECOVARIO 414 servo amplifier.
Advantages
The ECOSTEP 34T501-0700 brings servo performance to compact NEMA 34 axes on 325 V DC.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- High torque in small space: Up to 3.9 Nm peak torque and 1.87 Nm rated torque at 500 min⁻¹ support direct drive concepts without oversizing the motor.
- Genuine servo dynamics:50 pole pairs and operation with ECOVARIO 414 enable rapid start-stop cycles, precise positioning, and repeatable motion on high-dynamic axes.
- Configurable and approved: Options such as a 5 Nm holding brake, incremental or absolute encoders, and an IP65 variant help match the motor to the application. UL certification supports machine approvals in regulated markets.
Where it fits
Use this NEMA 34 high-torque servo motor where you need compact but dynamic rotary motion.
- Indexing and format adjustment axes in packaging and printing machines
- Feed, dosing, or metering drives in process and production equipment
- Rotary actuators and positioning units in assembly and handling systems
- Retrofit of stepper-based NEMA 34 axes to servo technology where higher dynamics and better positioning are required
Interfaces
The ECOSTEP 34T501-0700 is designed to integrate cleanly into JAT drive systems and standard industrial control architectures.
- Power and voltage range: Two-phase servo motor for DC link voltages up to 325 V DC, with rated performance specified for operation on the ECOVARIO 414 servo amplifier.
- Encoder and feedback options:
- Incremental: ABN encoders from 8,000 up to 160,000 inc/rev
- SinCos: 1000 periods per revolution
- Absolute: BiSS B with 17-bit single-turn and 12-bit multi-turn resolution
- EDS capable: All encoder options support simplified commissioning.
- System connectivity:M17 connector interfaces, matching mating connector sets, and pre-assembled motor, brake, and encoder cables are available. This simplifies wiring between the motor, ECOVARIO 414, and the control cabinet, helping to reduce integration effort.
