SGLTW

Iron core TW linear motors are composed of moving coils with a laminated iron-core and a pair of stationary magnet tracks that are placed on each side of the moving coils. The moving coil of the TW 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 TW is made of a row of rare earth magnets accurately placed on one side of the nickelized steel carrier plate. Two of the magnet carrier plates are used as a pair in a fashion similar to that of the coreless type linear motor. Stainless steel magnet covers guard against minor accidental damage to the magnets.

Features:

• Direct-feed mechanism for high-speed and high precision positioning.
• Yaskawa's unique construction principles of the TW linear motors negate the effects of the magnetic attraction force between the relative motor members.
• Lack of magnetic attraction helps to extend the life of the linear motion guides and to minimize operation noise.
