PERMANENT MAGNET-TYPE ELECTROMAGNETIC BRAKING CYLINDER

摘要

An electromagnetic braking cylinder comprises a cylinder portion, a piston portion, and an electromagnetic force-generating portion. The cylinder portion comprises first and second surfaces which face each other and define a first housing space, and an extended portion which extends from the second surface and perpendicularly to the second surface to define a second housing space. The piston portion is housed inside the first and second housing spaces and moves reciprocally along the extended portion. The electromagnetic force-generating portion comprises a first electromagnetic force portion fixed to the piston portion and a second electromagnetic force portion fixed to the cylinder portion, and moves the piston portion by applying electromagnetic force.
