FAQ

Frequently Asked Questions

If you share your target speed and load type, we can help shortlist the most suitable motor model quickly.

What is the advantage of a brushed coreless motor in compact drives?
It supports smoother response and lower inertia behavior, which helps in compact motion systems that need controllable output.
Why choose a planetary gearbox structure for this size?
It keeps the output aligned and supports stable reduction in a compact package, making integration easier in tight assemblies.
How do I choose between BLC1221-01 to BLC1221-04?
Start from your target output speed and load behavior, then compare rated speed and rated torque in the technical data table to narrow the best match.
Can I request a different lead wire routing or connector style?
Yes. Wiring length and exit direction can be adapted to match your layout.
