AL38xx Ironless Linear Servomotors

AL38xx | Ironless Linear Servomotors

In contrast to the AL2xxx series, the linear motors from the AL3xxx series have no iron core. This has the advantage that the coil part is not attracted by the permanent magnets and that cogging, i.e. the occurrence of cogging thrust due to magnetic forces between the permanent magnets and the iron core, is avoided. The benefits of ironless linear motors are particularly significant in semiconductor and plasma/LCD panel production, where highly synchronous operation and positioning quality are required. The lack of an iron core has the additional benefit of reduced weight and inductance of the coil part, leading to improved dynamics. Overall, an ironless linear motor is therefore the ideal drive, because it generates no interfering side effects in addition to the direct, backlash-free connection with the load. This enables the control loop gain to be set significantly higher in order to achieve the required positioning accuracy.
