Yaskawa SGL Linear Servo Motor Components Review: Specs, Price and Applications

Yaskawa SGL families provide direct-drive linear motor components for a custom axis. The selected forcer and magnetic track require guidance, position feedback, structure and a compatible SERVOPACK. They should not be confused with the complete Sigma Trac II stage.
Quick Verdict
Consider the component approach when travel or structure needs custom engineering. Use the exact family and winding datasheet for continuous force, attraction, air gap and thermal limits. Portfolio labels and unrelated family maxima cannot size the axis.

Design and Engineering Assessment
Motor topology changes magnetic attraction and guide loading. Use the selected forcer’s actual construction and force data rather than transferring another motor’s bearing assumptions. Mounting and track alignment are part of the mechanism design.
A large transient thrust can excite a compliant structure rather than improve settling. Include fixture stiffness, guide behavior, cable forces and payload modes when comparing a direct-drive axis with a screw or belt alternative.
Automatic motor recognition and serial feedback can reduce setup work in supported combinations. They do not establish correct air gap, mechanical alignment, coordinate scale or a satisfactory thermal duty for the assembled machine.
Structure and Commutation
Control track alignment, gap, guide support and end limits. Include attraction and process loads in the mechanical assessment.
Match winding, drive current/voltage and supported position/commutation feedback. Document the exact combination and cable interfaces.
Validate Production Duty
Verify direction, reference and sensor scale before tuning under load. Measure temperature and process-point settling through representative warm cycles.
Keep forcer/track, winding, feedback and drive identities controlled. A replacement or geometry change may require renewed thermal and motion validation.
Applications and Selection
Custom industrial direct-drive linear axes with engineered guidance and feedback.
For Yaskawa SGL Linear Servo Motor Components, 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
Advantages
Direct force for custom axis geometry
Multiple documented motor families
Avoids rotary-to-linear transmission
Limitations
Guidance and structure need engineering
Topology-specific loads matter
Recognition does not validate assembly
Who Should Consider Yaskawa SGL Linear Servo Motor Components?
Consider Yaskawa SGL Linear Servo Motor Components for custom industrial direct-drive linear axes with engineered guidance and feedback. Establish the required operating point and installation interfaces before choosing the configuration, and use a representative loaded cycle as the acceptance basis.
Yaskawa SGL Linear Servo Motor Components FAQ
Is an SGL motor a complete positioning stage?
No. Guidance, feedback, structure and controls are required.
Do all families have identical attraction loads?
No. Use the actual topology and datasheet.
Does peak force define continuous force?
No. Apply the selected thermal/transient limits.
Does recognition prove correct alignment?
No. Air gap and track mounting need mechanical checks.
Can any encoder be connected?
Confirm supported feedback and commutation.
Where should settling be measured?
At the actual loaded process point.
What should warm-duty testing include?
Motion, force demand, temperature and position behavior.
What identifies a replacement?
Forcer/track, winding, sensor, drive and validated configuration.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
