Hello
Recently, I'm studying about 'Simulation of FOC Using PMSM Model' in 'Target Support Package' to implement the PMSM driver by using the ezdsp2812 and DMC550.
But there are some question. What part of this model affects the rotation direction of the PMSM and How to modify that.
Could anybody help me with kindness? Thanks a lot! and I'm so sorry that I'm not fluent in English.

we can change the direction of any motors by reversing the supply voltage,what we have been applied to that motors...

Hi Lee Kwan Hyung,
Even though this is an old question, I think it is still relevant. Our FOC algorithms require a torque demand, that is sometimes coming out of the speed controller. Asking for negative torque will eventually spin the motor in the reverse direction. While using the speed controller, you can also ask for negative speed. I hope it helps, Cheers,
Antonin.

reversing the voltage sequence or torque is producing oscilating speed ,how to rectify this?
