Tecnotion TM Linear Motors Review: Specs, Price and Applications
Updated: 4 days ago
Tecnotion TM is a iron-core linear-motor family. Its current manufacturer table lists 60 – 360 N continuous force and 105 – 630 N peak force across the selected configurations. These are motor-family limits, not a payload or finished-stage accuracy specification.
Quick Verdict
A relevant compact direct-drive option when its lower force class meets the axis duty. Selecting the smaller suitable motor can reduce moving mass and installation space, provided the complete force-speed curve remains adequate.

Design and Engineering Assessment
An integral flexible servo cable can remove one connection point, but bend radius, cable route and repeated flexing still need a defined installation. A flexible cable is not automatically suitable for every torsional or continuous-flex duty.
A small coil must still reject its winding heat through the selected mounting. Stationary holding force and repeated short moves can produce losses even when average mechanical output power is small.
Force and the Motion Cycle
A linear motor applies force directly to the moving mechanism without a screw or belt transmission. Select the motor against acceleration, external process forces and the repeated thermal duty. Peak force supports a transient interval, while continuous force depends on winding losses and cooling. The useful operating point belongs to the selected coil, magnetic track and drive configuration.
Ironless and iron-core arrangements create different magnetic and mechanical tradeoffs. An ironless design can avoid iron-related cogging, while an iron-core design can introduce attraction forces that affect guidance and mounting. Neither topology removes the need to control the air gap, support the moving load and provide a suitable position-measurement system.
Guidance, Feedback and Thermal Integration
The motor components do not usually provide a complete guided axis. Bearings, track support, structural alignment and the encoder mounting must be designed together. Magnetic assembly forces can be significant, so fixtures and a controlled installation procedure are part of the integration effort. Changes to track geometry also need to preserve the intended commutation relationship.
The encoder measures a particular point on the moving structure. Cable forces, carriage compliance and thermal drift can still influence the position or process result elsewhere on the load. Evaluate the useful measurement point and the complete error budget rather than assuming that a fine encoder increment establishes the same accuracy everywhere.
Control and Acceptance
The selected drive must support the winding and feedback arrangement and provide the necessary continuous and peak current. Establish direction, commutation and limits before enabling full motion. Tune the loaded mechanism and assess tracking, settling or constant-velocity behavior against the actual process requirement. Faster electronic updates cannot compensate for an inadequately supported track or flexible structure.
Acceptance should include representative load, stroke, velocity and stationary dwell at operating temperature. Check service routing through the entire travel envelope, including reference and fault-recovery movements. Retain the coil and track identities, encoder alignment, drive parameters and geometry so that a replacement can restore the qualified axis rather than merely its mechanical appearance.
TM3z/TM6z Low-Voltage Windings Versus UC and UF Ironless Motors
Tecnotion separately describes TM3z and TM6z iron-core linear motors with a special Z winding for low-voltage operation. Its low-voltage page states48 VAC operation and compatibility up to400 VAC,with travel speeds up to5 m/s depending on bus voltage. These AC winding/interface descriptions must not be rewritten as a universal48 VDC power-supply instruction. Select the matched drive,bus and exact winding data.
The described TM3z/TM6z scope gives60/120 N continuous and105/210 N peak force for the two respective configurations. Available force at speed and continuous duty depend on the actual voltage,current and thermal installation. Iron-core attraction also loads the guidance;the machine must provide the prescribed bearing and mounting arrangement.
UC and UF are distinct compact ironless linear-motor families. The source describes60 VDC operation,continuous forces spanning10–39 N and peak forces36–85 N across separate models. Their lack of an iron core removes iron-core cogging;it does not make the complete guided stage frictionless or guarantee tool-point accuracy.
Choose between these constructions using actual force-speed duty,available voltage,height,guidance loads and smoothness requirements. Specify encoder,commutation,drive current,magnet track,thermal path and travel limits together. Verify loaded tracking,reversal and temperature on the completed axis rather than combining the smallest package and largest force from different family members.
Applications and Selection
OEM precision linear-motion axes using a matched TM coil, magnetic track, guidance and controller.
For Tecnotion TM Linear Motors, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons
