| High Torque Frameless Outrunner Motor WK3510 Datasheet

The TSL-BLDC-3510 is a high-torque frameless outrunner motor consisting purely of a compact stator and rotor. By eliminating traditional housings and bearings, this outrunner configuration allows for direct structural integration, offering engineers maximum torque density and exceptional space savings in a micro form factor.

Optimized for 12V systems, this 11-pole-pair motor delivers up to 0.16 N·m of peak torque. It is available in two configurations to balance weight and power: the high-torque WK3510CP-9 (magnetic sheet) and the ultra-lightweight WK3510CH-9 (magnetic ring), making it the ideal frameless outrunner motor for robotic joints, gimbals, and precision automation.
