Why Choose us

SLW Motor Highlights

  • Maximum-Efficiency Point Data You Can Design Around

    Each voltage variant lists current, speed, torque, output, and efficiency at the best efficiency point, so you can target a practical operating window instead of guessing from no-load speed.

  • Voltage Variant Choice That Changes Your Working Speed

    12V, 18V, and 24V variants shift the speed range and output level. This makes it easier to pick a configuration that matches your supply and the speed you actually need.

  • Driver Protection Planning Based on Stall Current

    Stall current is explicitly listed, which helps you size current limit strategy, startup ramp, and protection thresholds early in your controller design.

  • Compact Form for High-Speed Applications

    The Φ22×L38 envelope supports compact installations where speed capability matters and space is limited.

Custom

Beyond the Standard: Performance Customized

  • 01
    Efficiency-Point Targeting for Your Real Load
    We map your required speed and load torque to the closest efficiency-point neighborhood so your motor spends more time in an efficient region during normal operation.
  • 02
    Voltage Variant Selection Under a Fixed Power Budget
    If your supply is fixed at 12V, 18V, or 24V, we shortlist the variant that hits your speed target while keeping current within your driver and thermal limits.
  • 03
    Startup and Stall Margin Definition
    We review your startup inertia and load behavior against stall torque and stall current so your protection strategy does not trip during normal transients.
  • 04
    Current Limit Strategy for Stable Control
    We help define current limiting and acceleration ramps so the motor reaches target speed smoothly without overshoot or repeated current clipping.
  • 05
    Mechanical Envelope and Assembly Constraints Check
    We confirm the Φ22×L38 envelope, shaft interface expectations, and mounting approach so the motor fits the mechanism without late-stage bracket redesign.

FAQ

Frequently Asked Questions

For detailed selection guidance or project-specific requirements, please contact our team for further support.

How do I choose between 12V, 18V, and 24V versions?
Choose based on your available supply first, then use the maximum-efficiency speed and output to match your real operating point.
What does At Maximum Efficiency mean for selection?
It shows the speed, torque, and current where the motor converts electrical power most efficiently under load, which is often a better design target than no-load speed.
Why is stall current important for my driver?
Stall current is the worst-case current draw. It helps you set current limits and protection so the driver stays safe during startup and load spikes.
Can I use no-load speed as my working speed?
No. No-load speed is measured without load. Your working speed will be closer to the maximum-efficiency speed or the speed under your real load.
What information helps you confirm the right configuration quickly?
Share your supply voltage, target speed, estimated load torque, duty cycle, and available space for installation.
