Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What an integrated-motor actuator is
An integrated-motor actuator combines the servo motor and the screw in one body, often with the motor rotor driving the screw or nut directly instead of through a coupling or belt. Many use an inverted roller screw inside a hollow rotor for a very compact, stiff design. Some versions also integrate the servo drive and position controller, so the actuator needs only power and a command or fieldbus connection. The result is a shorter, sealed unit with fewer parts to align.
When engineers choose an integrated-motor actuator
Choose an integrated-motor actuator when space is tight, a clean sealed package is wanted, or decentralised control reduces cabinet size and cabling. It suits welding guns, robot cells and hygienic plant. The trade-offs are flexibility and service: the motor cannot be changed independently, thermal limits are shared and repairs may mean replacing the whole unit. A separate motor and actuator lets you change motor size or brand later and is often easier to source as spare parts.
How to specify the SCHUNK ELP compact linear axis
Send these with your enquiry and an engineer can confirm the right ELP compact linear axis variant or an equivalent:
- Force, peak and continuous (N)
- Stroke (mm) and speed (mm/s)
- Supply voltage: mains AC or low-voltage DC (V)
- Control interface: analogue, pulse, Modbus or industrial Ethernet
- Feedback and absolute position needs
- Duty cycle and ambient temperature (°C)
- Sealing and cleaning requirements (IP code)
Common mistakes to avoid
- Overlooking heat build-up when motor and screw share one housing
- Assuming any drive will run it, when integrated units may need a matched drive
- Not checking cable routing and connector orientation on the machine
- Forgetting spare strategy when the whole unit is one part
SCHUNK ELP compact linear axis: frequently asked questions
What is the SCHUNK ELP compact linear axis?
Linear direct-drive axis with integrated controller and digital I/O, set up with rotary switches for ten speeds; the ELP 050-H040 moves 3 kg horizontally over 40 mm at ±0.01 mm repeatability on 24 V. Published series figures include voltage 24 V, temperature 5 °C, temperature 55 °C, stroke 40 mm. It is made by SCHUNK SE & Co. KG; Specify Motion can help source it or propose an equivalent.
Who makes the SCHUNK ELP compact linear axis?
The SCHUNK ELP compact linear axis is made by SCHUNK (SCHUNK SE & Co. KG) and is listed here for engineers comparing options. Specify Motion is not affiliated with SCHUNK SE & Co. KG; brand names are used only to identify the product.
What is the voltage of the SCHUNK ELP compact linear axis?
The published series maximum voltage is 24 V. Individual models and sizes in the ELP compact linear axis range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the SCHUNK ELP compact linear axis?
Yes. On published figures, Tolomatic IMA Integrated Motor Actuator and Tolomatic ERD (incl. ERD-SS1 / ERD-SS2 stainless options) are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What are the advantages of an integrated motor actuator?
Combining motor and screw removes couplings, belts and the alignment that goes with them, so the actuator is shorter, stiffer and easier to seal. Versions with built-in drives also reduce cabinet space and cable runs. The downside is less flexibility for changing motor size and a larger, more expensive spare part.
Can an integrated actuator be controlled from a PLC?
Yes. Versions with built-in drives typically accept analogue, pulse and direction, discrete I/O or industrial Ethernet commands from a PLC. Versions without a drive need a compatible servo drive, often from a matched range. State the controller and network protocol at the outset so the right variant is selected.
