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 a tubular linear motor is
A tubular linear motor has its permanent magnets stacked inside a stainless steel rod, with a cylindrical stator of coils around it. Current in the stator coils creates thrust along the rod, which can move while the stator stays fixed, or the reverse. The magnetic field is fully enclosed and symmetric, so there is no net attraction force on the guidance and very little stray field. Many designs include integrated position sensing and temperature monitoring, and look like a pneumatic cylinder.
When engineers choose a tubular linear motor
Choose a tubular linear motor as a programmable, direct-drive replacement for pneumatic cylinders, where many positions, controlled force, high speed or long life are needed. It suits pick-and-place, packaging, assembly and test. The trade-offs are cost and side load: many designs need external guidance for radial loads, and heat must be managed in a compact body. For very long strokes or very high forces, flat linear motors or screw actuators may be better.
How to specify the LinMot P02-23 S (P02-23Sx80F-HP)
Send these with your enquiry and an engineer can confirm the right P02-23 S (P02-23Sx80F-HP) variant or an equivalent:
- Peak and continuous force (N)
- Stroke (mm) and speed (m/s)
- Moving mass and acceleration (kg, m/s²)
- Side load and guidance arrangement
- Vertical load and need for gravity compensation
- Supply voltage and drive (V)
- Environment, sealing and cooling
Common mistakes to avoid
- Applying side load directly to the rod without external guides
- Running vertical axes without a brake or spring compensation
- Overlooking heat in high duty cycles
- Choosing a tubular motor where a cheaper pneumatic cylinder is adequate
LinMot P02-23 S (P02-23Sx80F-HP): frequently asked questions
What is the LinMot P02-23 S (P02-23Sx80F-HP)?
A slim 23 mm tubular linear motor in LinMot's P02 range, sold alongside the PS01-23x80 HP stators. It is built for small, fast strokes where space is tight. Published series figures include peak force 67.1 N, continuous force 24 N, stroke 780 mm, linear speed 7.3 m/s. It is made by NTI AG; Specify Motion can help source it or propose an equivalent.
Who makes the LinMot P02-23 S (P02-23Sx80F-HP)?
The LinMot P02-23 S (P02-23Sx80F-HP) is made by LinMot (NTI AG) and is listed here for engineers comparing options. Specify Motion is not affiliated with NTI AG; brand names are used only to identify the product.
What is the peak force of the LinMot P02-23 S (P02-23Sx80F-HP)?
The published series maximum peak force is 67.1 N. Individual models and sizes in the P02-23 S (P02-23Sx80F-HP) 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 LinMot P02-23 S (P02-23Sx80F-HP)?
Yes. On published figures, MMF4 / MMD Magnet-free Track Linear Motor Modules and Akribis Systems AQM are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
How is a tubular linear motor different from a flat linear motor?
In a tubular motor, the magnets are inside a round rod and the coils surround it, so the field is enclosed and there is no net attraction. In a flat motor, magnets sit on a flat track, giving long strokes and high forces but often an attraction force. Tubular motors suit cylinder-style mechanisms; flat ones suit stages and gantries.
Can a tubular linear motor replace a pneumatic cylinder?
Yes, it is a common use. It offers programmable positions, force and speed control and long life without compressed air. It costs more upfront, so the case usually rests on flexibility, energy savings, cycle time or reduced maintenance. Check side loads and whether a guide is needed.
