This page is primarily to report new developments in actuators beyond my two articles on actuator torque. As I test new actuators I will report them here. If others measure torque for actuators I don't have I may report them as well, but will add a note on who measured them. Others may measure somewhat different torque than what I report here. However, my measures should all be internally consistent as I do them with the same equipment and the same way. I also measure the torque for an actuator at least five times, and use a laboratory power supply to insure the volage is what I intended for it to be.

For more information on actuators in general, and how to measure their torque, refer to the following series of three articles in the Ezone Inside Story micro column.

Actuator Torque, April 2003, Gordon Johnson

The table below has torque for actuators that have come out since my earlier articles or have been updated. For example, there are two sets of Leichty actuators. The old style used a different magnet material and weighed less and also put out less torque. Those are no longer available, but are presented here so people who own them can compare their torque to the new style Leichty actuators. The DU/BSD MiniAct can now be purchased with a larger magnet, and is noted as "lge magnet". EFlight Designs and JMP actuators are new since my original articles are are included here.
