    • A control system (120) for a motor (117) includes a current regulation controller (111) for generating a terminal voltage command. The terminal voltage command is used for converting a supply voltage to a three phase voltage to power a motor (117). The control system (120) also includes a terminal voltage command feedback module (108) for controlling the terminal voltage command. The terminal voltage command feedback module (108) compares the terminal voltage command to a determined voltage limit of the supply voltage and generates a d-axis current adjustment command in accordance with the comparison. The d-axis current adjustment command is used for reducing the terminal voltage command below the determined voltage limit. The control system (120) also includes a summer (119) coupled with the terminal voltage command feedback module (108). The summer (119) adds the d-axis current adjustment command to a d-axis current command received from a lookup table (e.g., 109).

    • The invention relates to a method and a device for controlling a synchronous machine which has a stator, a rotor and magnets disposed on the rotor. When the synchronous machine (S1) has been produced or serviced, a nominal value ?nenn is first set (S2) for the magnetic flux prevailing in the synchronous machine and a control system is flagged to indicate that no calibration has been carried out yet (S3). Tests are then performed repeatedly in order to check whether the synchronous machine has not been operated for at least a predetermined period of time (S4). If it has not, it is assumed that there is temperature balance between the stator and the rotor, such that the temperature to be measured at the stator is the same as the rotor temperature and can thus be used as a basis for calibration of the magnetic flux ?kalib (S5). The control system is then flagged, to indicate that the flux has been calibrated (S6). Normal operation can then continue (S7), checks being carried out continually to see whether the flux has already been calibrated (S8).
    • 提出了一种用于控制具有定子,转子和设置在转子上的磁体的同步电机的方法和装置。 在同步电机(S1)的制造或维护之后,首先设定用于同步电机中存在的磁通量的额定值ΔNn(S2),并且在控制器中设置标志以指示尚未执行校准(S3)。 然后,重复检查同步机是否至少在预定的时间段内未被操作(S4)。 如果是这种情况,则假设在定子和转子之间进行温度补偿,使得在定子处测量的温度等于转子温度,从而可以基于(S5)校准磁通量ΔKalib。 在控制器中设置指示执行流量校准的标志(S6)。 此后,可以继续正常操作(S7),其中持续检查是否已经发生流量校准(S8)。
