扭矩常量(Torque Constant)是永磁同步电机(PMSM)中描述电流与输出扭矩关系的核心参数,直接影响电机性能和控制策略的设计。
In step 1020, the torque data is analyzed to determine the torque constant KT. The data can be filtered and the torque constant KT determined by comparing the change in torque (no load to known torque loading) to the change in current (current at no load to the current at the torque lo...

Values of the axis moment of inertia JA, the torque constant KT, and the current scale factor AS may be supplied from the host system. Processors 38 and 42 perform integer arithmetic calculations to execute the velocity control algorithms. For clarity, the expressions of the algorithms are given...
The time constant TXG used by the first order delay unit 43 may be determined from a data map which relates the time constant with the lateral acceleration GY of the vehicle, for instance as indicated in FIG. 8. This data map is defined by three different curves KT1, KT2 and KT3 depen...
