Hello.
I´m trying to to build a model with simscape of an ASM. Instant of an constant of an Torqueload I want maki it as an feedback. For this I need to calculate the accaleration and devide it bei inertia. The problem is, when I´m using the PS Diviede-Block I get the error message:
An error occurred while running the simulation and the simulation was terminated
Caused by:
I´m using the equasions:
a = angular accelaration
s = angular displacement = A
w = angular velocity = W
a = w^2/s and then Torque = J * a
Anyone whocould tell where the mistake is or are there alternatives to this?
Thx

Hello Vitali,
It is possible that the rotational motion sensor is giving a value of 0 to the PS Divide block. Have you set the initial angle parameter in the sensor to a non-zero value?
