[No. 95] Actuator agony
Electromagnetic actuators (solenoids, relays, torque motors, etc.) comprise an important class of electromagnetic devices with a wide range of applications. They are used for short movements of mechanical parts, often with considerable force. They can also be used as sensors by virtue of the variable inductance that depends on the position of the moving element. Their design is well served not only by finite-element analysis, but also by thermal and dynamic analysis tools, and there may be a close link with control electronics in some cases. Actuator design is therefore truly a ‘multi-physics’ project...Read more
