Overview
The ECOSTEP 34T42-0560 is a high-torque rotary servo motor in the ECOSTEP 34T series, designed for dynamic positioning tasks requiring high torque density in a standard NEMA 34 (86 mm) flange. With a motor length of approximately 112 mm, a 12 mm shaft, and a mass of roughly 2.6 kg, it delivers significant torque in a compact footprint.
At a 150 V DC link, the 34T42-0560 reaches approximately 1.19 Nm rated torque at 1000 min⁻¹ and about 125 W rated power. Its stall and peak torque levels (up to 3.91 Nm) support demanding motion profiles in its operating range. The motor is UL certified and features a 50-pole pair design that enables high torque density and smooth servo operation. Standard protection is IP40, with an IP65 option available where higher environmental protection is required. The ECOSTEP 34T series is engineered for genuine servo operation and supports customer-specific winding adjustments for the 150 V DC range.
Advantages
The ECOSTEP 34T42-0560 provides torque-optimized NEMA 34 servo motor performance for compact but demanding axes.
- 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: High torque in a NEMA 34 frame with a 112 mm housing length supports strong motion control where installation space is limited.
- Direct drive capable: High stall and peak torque levels often allow direct drive concepts without a gearbox. This reduces external gear components and simplifies mechanics.
- High dynamic servo behavior: Genuine servo operation at 150 V DC supports rapid acceleration, precise speed control, and repeatable positioning on dynamic axes.
- Electrically and mechanically adaptable: Customer-specific winding adaptation, encoder variants, holding brakes, and shaft or flange options help match the motor to your required operating point and machine interface.
- Economic choice: The 34T series provides a very good price-to-performance ratio in its operating range compared to AC servo motors of similar torque class.
Where it fits
Use this compact high-torque NEMA 34 servo motor where you need precise positioning and strong torque in a limited envelope.
- Rotary or linear axes in assembly and handling systems operating at 150 V DC
- Packaging, indexing, and format adjustment axes with higher load or inertia but constrained space
- Direct drive rotary actuators or feed axes in special machinery or test stands
- Vertical or inclined axes where high torque and an optional holding brake support safe load holding
- Retrofit projects where an existing NEMA 34 interface must be retained but dynamic servo behavior and higher torque are required
These are application examples and do not represent specific approvals.
Interfaces
The ECOSTEP 34T42-0560 is designed for DC link voltages up to 150 V DC (rated at 150 V DC) and is optimized for use with the ECOVARIO 214 servo amplifier.
- Encoder options:
- Incremental: Standard resolutions from 8,000 to 160,000 increments per revolution
- SinCos: 1000 periods per revolution with programmable resolution
- Absolute: BiSS-B interface with 17-bit single-turn and 12-bit multi-turn resolution (individual resolutions up to 256,000 inc/rev or 19-bit single-turn available on request)
- Mechanical and protection options:
Optional 5 Nm holding brake (increases motor length and mass), shaft with key or long shaft, bearing flange variants, and IP65 housing option (shaft gland remains IP40). - Connection and cabling:
- Mating connector set 70.010 with M23 motor/encoder connectors and brake connector 70.014.
- Pre-assembled cable assemblies such as MOT33-132-513-0xx-000 (motor), BRM39-132-514-0xx-100 (brake), ENC47-491-503-0xx-000 (incremental), and ABS47-300-503-0xx-000 (absolute) support reliable wiring and shorten commissioning.
