© BCS Motion 2011 SGLGW Coreless GW linear servo motors are composed of moving coils and stationary magnet tracks. The moving coil has no iron content and is made of accurately resin molded motor windings. The stationary magnet track is made of two nickelized steel plates with accurately placed rare-earth magnets on each side. The steel plates are jointed at one end to form a U-channel to provide space for the moving coils. 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 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. 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 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 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. Sigma Trac SGT The Sigma Trac SGT is a series of linear actuators designed to reduce the work and unknown costs often involved in implementing linear motor technology into automation machines. Factory assembled to a precision aluminum base, Sigma Trac SGT delivers uncompromising linear motor performance in a bolt-on, plug-in package. Automatic motor recognition means start-up of the Sigma Trac is as quick and easy as a rotary servo system. Sigma Trac is well suited for single-axis point-to-point applications or for use in coordinated motion applications, faster cycle times are the common result. Speeds up to 5 m/s and acceleration up to 5 g are possible.
