SGLF Series
SGLF Series
Iron-core coil and magnet track components
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 prewound 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.
SGLF Series Features Highlights
- High winding space factor by concentrated windings (Factor approx. 70%)
- Edge cogging is cancelled by magnetic force of sub-teeth
- Magnetic attraction force between the moving and stationary members can be used effectively to increase the rigidity of the linear guidance system by pre-loading the linear motion bearings
- Magnetic pre-loading on certain types of linear motion bearings can help increase the systems’s frequency response, improving its deceleration and settling performances
- Compact profiles result in a low profile linear positioning systems
