The primary parts of these linear motors feature a low weight,
apparently zero pull forces between the primary and secondary parts,
a high efficiency and an absence of pulling force pulsations.
Owing to these properties, they can be used with advantage in
dynamic applications demanding the movement speed, acceleration,
accuracy and a low weight of the drive.
They are made in sizes with peak forces 80 to 1 900 N.
The secondary part of the induction linear machine is comprised of a simpler and more reasonably priced design which is made up of a squirrel cage. The squirrel cage is comprised of a winding mounted in slots or an aluminium (or copper) strip fixed on a steel pad.
The advantage of these undemanding drives is the possibility to be supplied straight from the standard distribution network 3x400 V/50 Hz without the need of using a frequency converter.
It is made in sizes with peak forces 100 to 500 N.
