motor equation problem

[Dyd-dyd]

Hello, I would like to ask about the motor equation. I know what Mq[0], Mq[1], Mq[2], and Mq[3] represent respectively，what means of <m.Mq[0] = - 1.5 * m.Zp * m.lambda * 20.f;>

This is to set the load torque corresponding to 20A current. Ideally, this should be wrapped in a function and implemented with respect to reluctance torque.
