摘要： The device (1, 2) according to the invention concerns a regulator comprising a circuit (1) generating an activation command (KEY_ON) for activating the regulator by bringing, to a first voltage higher than a high reference voltage, a bidirectional line (6) connected to a detection circuit for detecting a status of the activation command. The detection circuit comprises generation means (7, 9) for generating a fault signal from a flag (LAMP_ON) indicating a failure of the alternator, linking the line to a ground by means of a switching element (7), thus bringing the line (6) to a second voltage lower than a fault voltage lower than the high reference voltage, and the control circuit (1) comprises detection means (4) for detecting the fault signal. According to the invention, the control circuit further transmits a setpoint PWM signal having a maximum higher than the high reference voltage and a minimum lower than a low reference voltage higher than the fault voltage, a duty ratio of the setpoint signal being representative of a setpoint voltage (V0) of the regulator.

摘要： A rotor temperature monitoring method and system for a permanent magnet synchronous motor. According to the method and system, an a-phase line current and a b-phase line current of a stator of a permanent magnet synchronous motor are obtained as a first line current and a second line current (S101); further, a line voltage between the a-phase and the b-phase of the stator is obtained (S102) and a rotating speed of the rotor of the permanent magnet synchronous motor is obtained (S103); and then, the first line current, the second line current, the line voltage, the rotating speed of the rotor, an inductance parameter of the permanent magnet synchronous motor and a temperature characteristic equation of a permanent magnet of the rotor are substituted into a preset rotor permanent magnet temperature expression to calculate and obtain the temperature of the rotor (S104). By means of the rotor temperature monitoring method and system, it is unnecessary to embed a temperature sensor in the rotor to monitor the temperature of the permanent magnet of the rotor, thereby avoiding the problem of low system reliability due to the configuration of the temperature sensor to monitor the temperature of the permanent magnet of the rotor.

摘要： An integrated hybrid rotary assembly is configured to provide power, torque and bi-directional communication to a rotatable sensor, such as a lidar, radar or optical sensor. A common ferrite core is shared by a motor, rotary transformer and radio frequency communication link. This hybrid configuration reduces cost, simplifies the manufacturing process, and can improve system reliability by employing a minimum number of parts. The assembly can be integrated with the sensor unit, which may be used in vehicles and other systems.
