Torque Calculation for Magnetic Coupling
Torque Calculation for Magnetic Coupling
(OP)
Has anyone found any torque calculations for magnetic coupling; i.e. what magnetic strength is required to support the torque from the motor shaft? I have done a bunch of online research and it seems the only way to calculate this number is by running simulations; which is hard to believe because there are a lot of companies that manufacturer mag drive pumps and I can't believe that they run simulations every time they design a new pump. There has to be some sort of standard or rough calculation. thread340-374735: Torque Calculation for Magnetic Coupling





RE: Torque Calculation for Magnetic Coupling
Sometimes an existing design can be lengthened/shortened to a desired torque since it'll scale linearly.
There are a number of analytical expressions published in IEEE Transactions on Magnetics by Furlani. With a moderate amount of programming ability, one can write a program that'll take the relevant parameters and calculate the torque directly.
Do you have a particular application or specific set of dimensions in mind? You'll find a number of people in this forum are happy to run a feasibility analysis in their software.

It didn't look simple from a quick skim, but I guess it's all relative
