Coreless Motors
Overview
Canon's coreless motors create high power output
from a small package. Their low moment of inertia provides
quick response rates and high controllability. Our coreless
motors have demonstrated their high reliability in many
applications including cameras and pumps. Customization,
like the addition of reduction gears, is available.
Winding changes and other options are possible to meet customized performance requirements
