Selection Guide

Servo Motor Selection Guide

This guide helps teams select ZS servo motor models by frame size, power tier, torque reserve, and integration constraints.

Best practice: lock mechanical envelope and motion duty before narrowing power class.

Selection Workflow

Start with application boundaries, then narrow to a practical shortlist.

  1. Step 1

    Lock axis load and motion profile

    Confirm inertia, peak load, acceleration window, and positioning repeatability before model selection.

  2. Step 2

    Match frame size and power tier

    Choose frame 40 to frame 130 by installation envelope, required torque reserve, and continuous duty intensity.

  3. Step 3

    Freeze interface and commissioning plan

    Align nominal voltage, encoder strategy, and CANopen or RS485 integration checkpoints with controller team.

Use this matrix to screen options before requesting detailed proposal and datasheets.

Decision Factor How to Choose Quick Verification
Mechanical envelope Start with frame size boundary first, then narrow power tier within that mounting constraint. Verify motor body dimensions, shaft interface, and cable routing clearance in CAD.
Torque reserve Select model with practical continuous margin above nominal operating load, not only nominal power. Check rated and peak torque against acceleration and holding requirements.
Duty stability For high-cycle applications, prioritize higher thermal margin and conservative loading ratio. Run duty-cycle simulation for continuous operation and validate temperature rise limits.
Control integration Choose communication and feedback strategy early to avoid late software remapping. Confirm CANopen or RS485 mapping with controller diagnostics and commissioning flow.

Scenario-to-Model Mapping

Start from operating scenario and architecture targets to jump directly to a practical shortlist.

Compact positioning axis

Tight installation space with light-to-medium dynamic load

Start from ZS-40-100W for compact integration and responsive positioning.

Frame-40 option supports constrained packaging while maintaining stable closed-loop behavior.

Open ZS-40-100W
General industrial actuation

Medium-duty axis with balanced speed and torque demand

Use ZS-80-1000W as baseline and adjust by load spectrum.

Frame-80 and 1kW tier covers common motion modules with practical torque reserve.

Open ZS-80-1000W
High-load motion module

Large inertia, high-force handling, or continuous heavy cycle

Move to ZS-130-3800W for stronger continuous output and duty robustness.

Frame-130 high-power tier supports demanding applications with larger torque headroom.

Common Selection Mistakes to Avoid

These are high-frequency issues seen during integration and pilot validation.

  • Selecting by power only: Evaluate frame size, installation constraints, and torque reserve together before final lock.
  • Ignoring peak acceleration demand: Use acceleration and load transients to validate peak torque margin, not rated points alone.
  • Late communication alignment: Freeze CANopen or RS485 mapping during architecture stage to avoid commissioning delays.
  • No duty-cycle thermal review: Run continuous duty verification and temperature checks before pilot release.

Selection FAQ

How do I choose between frame 60 and frame 80 quickly?

Use installation envelope and torque reserve first. If cycle load or acceleration is near frame-60 boundary, move to frame-80 for stability margin.

Are all ZS models aligned to the same speed class?

Yes. Current ZS guide lineup is aligned to a unified 3000 rpm class for easier model comparison and integration planning.

What data should be included in quote requests?

Provide target load, motion cycle, mounting space, required precision, interface protocol, and annual volume.

Can servo selection be coordinated with motor controller planning?

Yes. Servo model, controller mapping, and communication diagnostics should be confirmed together in the same integration review.
