Abstract
Described is a method of aligning a stationary rotor of a polyphase synchronous motor having a permanent magnet rotor to a configured rotor angle (θ). The method includes determining corresponding polyphase drive voltages for the synchronous motor based on a user-specified value of a two-axis synchronously rotating reference frame vector voltage (V) for a selected one of two axis of the two-axis synchronously rotating reference frame. Then, determining corresponding polyphase drive voltages for the synchronous motor; and applying said polyphase drive voltages for a predetermined, selected, or calculated time period to rotate the stationary rotor to align said rotor with said configured rotor angle (θ).
