LS Series Brushless Motor

Introducing ThinGap’s LS Line of Slotless, Frameless Motor Kits

ThinGap’s LS line targets low speed, high precision applications such as gimbals, optics, and precision robotics.
Highest torque density with high power capability. Low thermal resistance at any speed.

Features include:

  • Smooth motion with zero cogging and ultra low torque ripple when paired with a sinusoidal drive
  • High peak torque to continuous torque ratio
  • Optimized for ultimate torque density
  • Stationary lamination stack for typical bore mounting
  • 3 phase brushless, sinusoidal waveforms < 1% THD
  • Non-saturating facilitates very high peak torque (typically >4:1)
  • Exceptionally large clear apertures
  • Frame-less kit facilitates deep integration
  • Large through hole
