Hello <\/p>\n

I am trying to simulate double rotor axial flux motor to find torque at given current using magnetostatic. <\/p>\n

The way I am trying to do is by converting my desired q-axis current in to ia = iq*(-sin(theta)), ib = iq*(-sin(theta – 2pi\/3), and ic = iq*(-sin(theta + 2pi\/3) and set excitation to each coils and check maximum torque at different rotor angle. (So consequently I need more or less similar value of torque throughout different rotor angle)<\/p>\n

But to do this I need to align rotor to each phase of a stator.<\/p>\n

question 1: how to determine where phase a,b,c of stator is?<\/p>\n

question 2: how do I set the initial rotor position? (do I align a magent of a rotor to d-axis or q-axis or somewhere?)<\/p>\n

 <\/p>\n

Kind regards<\/p>\n
