左键双击鼠标可以重置缩放，若出现更多的警示信息（图6），重复此检查过程，直到没有剩余的警告。接下来可以模拟具有新型几何结构的模型，可和之前的仿真结果进行比较(电磁计算部分)图6 选择Calculation选项卡，然后做如下参数设置，在Performance Tests栏中只激活Torque, Back EMF和Cogging Torque 这几个选项，点击Solve ...
The back emf is then used, along with a measured input voltage and measured motor current to calculate the electrical resistance of the motor winding, which is proportional to the temperature of the motor. The electrical resistance value is then compared to a threshold value and, in the case ...

In both simulation and experiment, the back calculation and tracking and low-order designs are shown to exhibit clear performance advantages over the reset strategy. Index Terms—Anti-windup (AW), constraints, current limitation, nonsalient, optimal, permanent-magnet synchronous motor (PMSM), ...
We propose a position sensorless control scheme for a four-switch,three-phase brushless DC motor drive,based on the zero crossing point detection of phase back-EMF voltages using newly defined error functions(EFs). The commutation in-stants are 30° after detected zero crossing points of the EFs...
Figure 6b. Calculation of the current back emf angle GAMMA. Velocity Setup Setting CL_VMIN_EMF and CL_VADD_EMF properly is motor dependent. Thus, connect a current probe to one phase of the motor cables and a voltage probe on the same signal line. To set appropriate velocity limits please...
The back emf is then used, along with a measured input voltage and measured motor current to calculate the electrical resistance of the motor winding, which is proportional to the temperature of the motor. The electrical resistance value is then compared to a threshold value and, in the case ...
To operate the IPMSM motor at a speed higher than its nominal speed, the resulting back-EMF must be reduced in order not to exceed the maximum output voltage of the inverter. This reduction is performed by setting the d-axis stator current to a negative value to reduce the rotor flux link...
