    EMS Magnetic software

    Dear guys, I want to invest in a electro-magnetic FEA software, I know Maxwell 3D, Ampere 3D, and Flux 3D, and I found on internet EMS (which is working with SolidWorks). I'm just curious to know if it's a good product and its cost. Does anybody knows about that software? In advance thank you...

    Spiral spring design

    Hello Israelkk, thx for your answer, the actuator will run for a million cycles, and I would like to have about 15 mNm preload torque and after aa angle stroke of 70° the spring torque would not exceed 40 mNm. The OD of the spring will be about 38mm and I assum that the ID will be arround 20mm...

Unfortunately I have no experience in the design of such spring. first question: does the torque versus angle formula is linear or what is the calculation formula? 2nd: what is the...

    Friction factor

    hello diamondjim, The hardness would be around 50HRC, I wanted to use steel but the steel-steel friction factor is about 0.1. Do you have any idea of material pair which will have a friction factor of 0.2 with lubrication Electro-mechanical designer

    Friction factor

    Hello to everybody, I'm looking forward materials which have a friction factor of about 0.2 (lubricated) and the higher hardness. Does it make sense to search such marterial? In advance thanks! JamesXIII Electro-mechanical designer
