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 7):
A 120\u00b0 control system for controlling a permanent magnet synchronous machine having a permanent magnet rotor and a three-phase stator, the machine being associated with a control inverter for controlling the stator of the synchronous machine, and the system comprising:\n three Hall effect sensors and control means coupled to the outlets of said sensors and configured to receive the three measurement signals taken simultaneously by the sensors, the three Hall effect sensors being mounted on the synchronous motor so as to have a central sensor and two lateral sensors, the two lateral sensors being placed at a mechanical angle of 120\u00b0/p away from the central sensor relative to the axis of rotation of the synchronous machine, p being the number of pairs of poles of the synchronous machine, \n wherein the control means comprise a signal processor module suitable for 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.
