Design of the motors
The linear servomotors from the AL38xx series are ironless three-phase motors for high-quality servo
applications. In conjunction with our digital servo drive, they are particularly suitable for positioning tasks in
the semiconductor industry with demanding requirements in terms of synchronism and precision.
The motors from the AL38xx series are intended to be operated exclusively by the digital servo drive with
speed and torque control.
The linear servomotors have permanent magnets in the secondary section. This advanced neodymium
magnetic material makes a significant contribution to the motors' exceptional dynamic properties. A three-
phase coil unit supplied by the servo drive is housed in the coil unit. The motor has no brushes; the
commutation being implemented electronically in the servo drive.
Furthermore, a feedback system is necessary for operation. The suitable feedback system must be selected
on the basis of the application requirements. Dynamics, speed, contamination levels, resolution and the
servo drive employed must be considered
