The series AL2000 linear motor
The motors of the AL2000 series are three phase ironcore linear motors in a very compact design. Coils with
iron core are mounted in the slide. The slide moves over the magnetplate. The small gap between the plate and
the slide is established by the use of rails and bearings. Because of the small airgap the magnetic resistance
between coils and magnets is low. This results in a high magnetic force.
•
Some characteristics of this linear motortype are
High peak force (up to 2000 N).
•
High continuous force.
•
Relatively small attraction force
•
Low heat dissipation.
•
Controlled low cogging level.
•
Dynamics and accuracy at an intermediate level.
•
High speed (up to 10m/s).
•
Moderate price of magnet plate.
