Effective calculation
In an effective calculation, the travel path of the application is added to the length of the effective section of the coil unit and then divided by the length of the magnetic plate.
Effective section
The effective section contains are the coils of the coil unit. In this part the force is generated that drives the motor forward. The remaining installation space includes the wiring.
Position | Meaning |
|---|---|
A | Passive part of the cable side |
B | Passive part of the end side |
C | Effective section |
D | Housing length = sum of A + B + C |
 | Example of effective calculation: The values used here can be found in the following tables. Travel path = 490 mm Effective range of the coil unit AL8121 = 76 mm Length of magnetic plate AL8523 = 384 mm
Required number of magnetic plates: (490 mm + 76 mm)/384 mm = 1.47 magnetic plates < 2 magnetic plates are required. |
