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
