SGLFW

Iron core FW linear motors are composed of moving coils with laminated iron-core and single sided stationary magnet tracks. The moving coil of the FW linear motor is composed of laminated iron core and pre-wound coil bobbins inserted into the slots located on the laminated iron cores. The entire coil unit is permanently encapsulated in a thermally conductive resin body to give structural rigidity. The magnet track of the FW is made of a row of rare earth magnets accurately placed on one side of the nickelized steel carrier plate. Stainless steel magnet covers guard against minor accidental damage to the magnets.

Features:

• Direct-feed mechanism for high-speed and high-precision positioning.
• The magnetic attraction force between the moving and stationary members can be used effectively to increase the rigidity of the linear guidance by preloading the linear motion bearings.
• The magnetic preloading on certain types of compliant linear motion bearings can help increase the system’s frequency response, improving its deceleration and settling performances.
