Why Choose us

SLW Motor Highlights

  • Round housing for rigidity-focused builds

    The cylindrical form is easier to seat in round cavities and helps maintain a stable interface when the gearbox is used as a compact torque module.

  • Ratio choices centered on usable torque growth

    The 6–360 span supports both moderate reductions and torque-forward reductions without forcing a housing change.

  • Direction selection protects layout simplicity

    Same or reverse output helps match the linkage direction when your mechanism routing is constrained.

  • Custom shaft interface reduces assembly variability

    Defining the shaft end early can reduce stacked adapters and improve repeatability when transmitting higher torque in small assemblies.

Custom

Beyond the Standard: Performance Customized

  • 01
    Wiring & Lead Routing
    Lead routing can be arranged around the round housing to avoid interference with mounting surfaces and coupling space, ensuring efficient cable management.
  • 02
    Customized Shaft Interface
    Shaft end shape can be matched to your coupling method, improving anti-slip performance and assembly repeatability.
  • 03
    Installation Alignment
    Provide mounting direction and load orientation to ensure the gearbox configuration supports stable operation under actual conditions.
  • 04
    Control System Coordination
    For frequent start/stop or reversing operations, aligning control behavior with load characteristics helps minimize peak torque events and maintain consistency.
  • 05
    Application-Specific Tuning
    Share load type and duty cycle so that reduction ratio, output direction, and shaft interface can be tailored for optimal performance in real-world use.

FAQ

Frequently Asked Questions

A larger gearbox diameter is typically selected to improve rigidity and torque margin.

How do I choose between 15mm and smaller spur gearboxes?
15mm is typically selected when you want more rigidity and torque margin in a compact package, especially when the gearbox body is part of the mechanical support.
Which ratios are better for faster output motion?
Lower ratios such as 6 and 9 are commonly used when output speed is prioritized over torque.
When should I select ratios above 100?
Higher ratios are usually chosen when torque margin and stable low-speed output matter more than speed.
Can I choose output direction?
Yes. Same or reverse output can be selected to match your mechanism layout.
What do you need to define a custom output shaft?
Your coupling method, assembly approach, and any slip or positioning constraints.
