Hello Everyone,
Technical question on Simscap PMLSM block.
The PMLSM function for linear motors shown equality between the force and the back-EMF constants as for rotating motors.
But they aren’t equal for linear motors in actual life.
Thus, Which constant should be taken to calculate the magnetic flux of permanent magnets of linear motors?
Can it be calculated from the motor datasheets as an input to the PMLSM block?
Thanks in advance,
Dima Roso.

This would depend what information is available in the datasheet. This formula can be used to compute the relevant parameter based on what parameterization is used. What we need to careful is what definition is being used in the datasheet as sometimes they are referring to line voltage or phase voltage, RMS or peak, etc.
