ABSTRACT:
A method for controlling and protecting electric motors, specially permanent magnet motors electronically actuated by a control system. The system includes a three-phase inverting bridge, in which the position of the rotor can be monitored by using a position detector physically attached to the axle or through the tension induced in the coils by the magnet, in order to correctly control actuation by the control system. The present invention is also directed to a system for controlling electric motors and an electric motor system. The system includes continuously reading the position detector until a minimum expected time has passed. After the minimum expected time has passed, there is continuous reading of the position detector until a maximum expected time has passed to detect if a position change of the rotor is sensed.
