WebA three-phase synchronous motor has no starting torque. It has to be brought up to speed or as close to it as possible by some other means so that it can pull itself into synchronism. Once up to speed, the rotor field can be excited with direct current and the rotor is, in effect, then dragged around at the same speed as the three-phase stator ... http://www.kurratul.weebly.com/uploads/3/3/4/6/3346099/a_textbook_of_electrical_technology_vol._2_-_theraja-p1.pdf
Websynchronous machine stator admittance in the direct, Y d(js), and quadrature, Y q(js), axes or the circle diagram of an induction motor was proposed in (Khemliche et al., 2004; Shiqin et al., 2008; Liuchen, 1996; Guha and Kar, 2006).

This example implements the field-oriented control (FOC) technique to control the torque and speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a quadrature encoder sensor. For details about FOC, see Field-Oriented Control (FOC).
