Key Features

This model is built around feedback-driven control. The encoder and pin-defined wiring make it suited to compact mechanisms where open-loop speed drift or missed steps are not acceptable.

  • Integrated encoder enables closed-loop speed or position control in compact modules
  • Planetary gearbox keeps the output coaxial, simplifying coupling in tight inline layouts
  • 3V–24V applied range supports both low-voltage portable designs and higher-voltage control platforms
  • Pinout-defined signal routing helps standardize integration for motor phases and Hall/encoder signals
  • Technical data provides rated and stall references for controller limit setting and protection planning

Why Choose us

SLW Motor Highlights

  • Closed-Loop Control in a 12mm Class Module

    An encoder-equipped gearmotor helps you correct speed variation under load and support repeatable motion in compact assemblies.

  • Pin-Defined Integration for Signal Discipline

    The pin mapping separates motor drive phases from Hall/encoder signals, helping reduce wiring ambiguity during system integration and testing.

  • Gear Reduction for Low-Speed Stability

    A planetary gearbox helps achieve low output speed with stable torque delivery, making control smoother at slow travel or indexing conditions.

  • Control Limit Planning From Rated and Stall Data

    Rated current and stall torque provide boundaries for current limiting, overload response, and safe startup behavior.

Custom

Beyond the Standard: Performance Customized

  • 01
    Control Mode Fit: Speed Loop vs Position Loop
    We align your use case to the encoder feedback method so the controller logic matches whether you need stable RPM regulation or repeatable position movement.
  • 02
    Signal Routing Strategy for Noise Control
    We review your wiring path and connector approach so encoder/Hall signals remain stable near motor phase lines in compact housings.
  • 03
    Current Limit and Protection Threshold Setup
    We map rated current and stall torque to your driver settings to reduce thermal stress during acceleration, jams, or repeated start-stop duty.
  • 04
    Low-Speed Smoothness Tuning With Gear Reduction
    We evaluate whether your application benefits more from higher reduction for smooth low-speed travel or lower reduction for faster response and shorter move time.
  • 05
    Connector and Pinout Adaptation for Assembly Workflow
    We can adapt connector type or harness routing to fit your assembly sequence so the encoder cable path does not conflict with mounting or moving parts.

FAQ

Frequently Asked Questions

If you share your available space and the driven load type, we can help narrow the most suitable configuration quickly.

Why choose an encoder motor instead of open-loop drive?
An encoder lets the controller correct speed or position errors under load, improving repeatability and reducing drift.
What does the rated current help me decide?
It helps you size the driver and set current limits for continuous operation without overheating.
How should I use stall torque in design?
Use it as a boundary for brief overload or jam events and to plan protection behavior, not as a continuous operating point.
Is this suitable for low-speed positioning tasks?
Yes. The planetary gearbox supports low-speed output, and the encoder helps stabilize motion under load changes.
What should I prepare to confirm compatibility quickly?
Share your supply voltage, target speed or motion profile, load type, and whether you need speed regulation or positioning feedback.
