Design of the motors

The linear servomotors from the AL2xxx series are brushless three-phase motors for high-quality servo applications. In conjunction with our digital servo drives they are particularly suitable for positioning tasks in industrial robots, machine tools, transfer lines, handling equipment, textile machines, packaging machines, etc. with high requirements for dynamics and stability. The motors from the AL2xxx series are intended to be operated exclusively by a digital servo drive with speed and torque control.

The linear servomotors are equipped with permanent magnets in the magnetic plate. 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 must be considered (see also the section entitled Magnetic Encoder System (MES) (optional)).
