Abstract:
A permanent magnet synchronous machine includes a permanent magnet rotor and a three-phase stator, the machine being associated with a control inverter for controlling the stator of the machine. A method of controlling the machine includes taking three simultaneous measurements by three respective Hall effect sensors arranged to have a central sensor and two lateral sensors, the two lateral sensors being placed at 120°/p mechanical relative to the central sensor about the rotation axis of the rotor, where p is the number of pairs of poles of the machine; determining the position of the rotor based on the three measurements; controlling the control inverter as a function of the determined position of the rotor; and prior to controlling the inverter, applying a time delay to the three measurement signals so that the control of the control inverter takes account of a variable desired lag angle.

Claim (Index 4):
The method according to  claim 1 , wherein, the values, in seconds, of the delay to be applied for each value of the speed of rotation of the synchronous machine are calculated beforehand using the following equation: Delay = ( \u03b4 initial - \u03b4 desired ) \ue89e P 360 where \u03b4 initial  is the angle between the Hall effect sensors and the axes of the coils of the synchronous machine expressed in degrees, \u03b4 desired  is the desired lag angle expressed in degrees, and P is the electrical period expressed in seconds.
