DC electric micro-motor
ø 2 mm
New Scale Technologies
This custom rotary SQUIGGLE motor has twice the torque of similar-sized DC micro motors. It needs no gear reduction mechanism, delivering high peak torque at sustained speeds as well as high holding torque. The patented SQUIGGLE design uses friction to directly drive the stator and lock it in place with the power off. This rotary piezoelectric motor also offers higher precision than DC micro motors.
This design can be optimized for other design parameters including smaller size or higher speeds. It is scalable to less than 2 mm diameter. The chart below illustrates the general tradeoff between motor diameter and torque.
