Recent studies have shown that tunable magnets (soft permanent magnets) can significantly reduce Joule heating in electromagnetic actuators. To achieve high motion accuracy and repeatability, this article proposes a novel actuator design with a linearized force-flux relation. In prior designs of variable reluctance tunable magnet actuators,...

In the semiconductor industry, the demand for a continuously higher throughput puts tough requirements on the force capacity and accuracy of actuators. Reluctance actuators, as a promising alternative to the present state-of-the-art Lorentz actuators, are capable of achieving much higher force densities. On the other hand, reluctance actuators...

To increase the accuracy of high-precision motion systems, the heat dissipation in electromagnetic actuators must be reduced to limit thermal expansion. Variable Reluctance Actuators have a high-frequency bandwidth but suffer from heating when providing high forces for sustained periods of time. Tunable Magnet Actuators can provide a large force...

The recent development of a hybrid tunable magnet actuator proposes to eliminate Joule heating when maintaining a force or position offset. By controlling the remnant magnetic flux in an AlNiCo magnet within the actuator, the actuation force can be linearly varied and maintained. While a method for tuning the magnetisation state of the magnet...
