    • A tracking circuit and method are disclosed for tracking an orientation of a rotor of a motor, such as a three-phase sensorless, synchronous, sine wave permanent-magnet motor, during a loss of source power to a motor drive. The circuit comprises an electrical energy store for generating a drive signal during periods of loss of source power, and a phase locked loop, which is arranged to receive as inputs the drive signal and an induced signal generated during rotation of the rotor during the periods of loss of source power, so that variations in the drive signal become locked to variations in the induced signal. The method comprises storing electrical energy in the store during periods of source power supply to the motor drive and generating a drive signal from the electrical energy store during periods of loss of source power to the motor drive. The method further comprises varying the drive signal in dependence of an induced signal generated by the rotation of the rotor during a loss of source power to the motor drive, to track the orientation of rotor.

    • In an electric power steering system, a control signal output section outputs independent dual-system control signals to driver circuits that are disposed in connection with independent dual-system motor coils. The control signal output section gives high priority to the output of the control signal to the other system, when the occurrence of energization failure is detected in one system. When the energization failure occurring phase is only one phase and the value of the basic command (Iq *) exceeds the upper limit (Iq _max / 2) of the priority command (Iq *_x), the control signal output section outputs the control signal to the driver circuit in the system where the energization failure has occurred in order to supply electric power in which the two phases other than the energization failure occurring phase are used as the energized phases on the bases of the complementary command (Iq *_y) that corresponds to the excess of the upper limit.

    • The invention relates to a method and a device for operating an asynchronous motor (1) with double feeds, having a stator (1 a) connected to a grid and a rotor (1 b) connected to an inverter (6), said inverter (6) being designed such that it impresses a target value for an electrical variable in the rotor (1 b). In a method according to the invention, after detecting a transient grid voltage change, a target value for the electrical variable determined from at least the rotor flux and the stator flux is impressed in the rotor (1 b) such that an active reduction in the torque occurring during the transient grid voltage change is achieved. The target value of the electrical variable is preferably determined from a suitable weighting of the stator flux, rotor flux, stator voltage, stator current, rotor current, and, if available as a measured variable, stator voltage. In this manner, torque peaks are similarly prevented for various types of grid faults, and the maximum time value of the rotor current is optimally reduced, and a rapid return to regular operation of the asynchronous motor is made possible.
