LINEAR MOTORS

SYNCHRONOUS LINEAR MOTORS
These motors are three-phase synchronous servomotors with the winding distributed in the primary part excited by permanent magnets of the type Nd-Fe-B that are a component of the secondary part of the linear motor. The type of cooling of primary parts is IC40 (natural cooling by the motor surface), or water cooling IC3W7 with an integrated or additional cooler. Synchronous linear motors are delivered in three series.
Series L3S, L3SK Compact version in the sizes with force of 50 to 16 000 N, thrust speed from 0,01 mm/s to 15 m/s, and module of the active surface width 25 mm. Active width 25-250 mm (size L3S025-L3S250).
Series L2S, L2SK Compact version in the sizes with force of 50 to 10 000 N, thrust speed from 0,01 mm/s to 15 m/s, and module of the active surface width 20 mm. Active width 25-160 mm (size L2S040-L2S200).
Series L1S, L1SK Standard version in the sizes with force of 50 to 8 000 N, thrust speed from 0,01 mm/s to 15 m/s, and module of the active surface width 25 mm. Active width 25-160 mm (size L1S025-LS160).

SYNCHRONOUS LINEAR MOTORS with primary part without ferromagnetic materials
Primary parts of these linear motors are characterized by low mass, almost zero attractive forces between primary and secondary parts, high effectiveness and absence of thrust force pulsations. Because of these properties they are convenient for dynamic applications with high demands for thrust speed, acceleration, accuracy and low mass of the drive.
Series LNS The motors are produced in the sizes with peak forces 80 to 1 900 N (sizes LNS025-LNS100).

INDUCTION LINEAR MOTORS
The secondary part of the induction linear machine is made in a more simple and cost-effective version based on the squirrel cage. The squirrel cage consists of the winding placed in slots or of the aluminium (or copper) strip attached to the steel support plate. These undemanding drives have an advantage of the possibility of a direct supply from the standard distribution network 3 x 400 V/50 Hz without a necessity of application of a frequency converter.
Series LA The motors are produced in the sizes with peak forces 100 to 500 N.

TUBULAR LINEAR MOTORS
Tubular linear motors consist of the fixed cylindrical primary part with the winding being intensively cooled by water and of the external moving part made as a steel sleeve with permanent magnets. Due to the rotational symmetrical arrangement of the machine attractive magnetic forces between primary and secondary parts are compensated so that they are not transmitted to the driven equipment. The tubular motor has an advantage of the absence of thrust force pulsations.
Series LTSK The motors are produced in the sizes with the force 300 – 900 N in the frameless version (version E), or with the frame consisting of the aluminium section.
