This paper deals with a way of computation of the mechanical behavior of Permanent Magnet synchronous couplings . This method is based on the calculation of the forces between the magnets of the device. The formulation of these forces is based on magnetic pole theory. The computation is done using a semi-numerical integration method. This method has been validated in test cases and appears to be very advantageous in terms of calculation time and precision. So this solution appears to be a good way to study and design this kind of devices.
