In a permanent magnet machine, the current phase angle plays an important role for maximum torque per ampere generation. For the surface mounted permanent magnet machines, the current in phase with machine back EMF generate maximum torque. However, this is not true for interior permanent magnet motors due to the presence of reluctance torque.
