Two-Phase PMLSM mathematical model
显示 更早的评论
Hi,
I have troubles in creating the two phase PMLSM mathematical model which I´m using in my thesis.
The products that I´m using:
The Inverter is supplied by 74V DC and converts the DC voltage for supplying the motor, which has Two-Phases
I´ve looked threw many thesis, and matlab examples/threads etc.. but I can't really manage to create mathematical model of two phase PMLSM, or adapt some existing one to my needs.
Can I somehow make the inverter + the motor from basic simscape blocks? Or could you please point me to some literature that could help me solve this problem?

Hi Stepan Dvorak,
To implement a two phase PMLSM mathematical model from Simscape blocks, you can use:
- Basic power electronics blocks (e.g., MOSFETs, diodes, and capacitors) to create the inverter.
- You can also use the “Universal Bridge” block in Simscape to model the inverter. You can configure it as a two-phase inverter to supply your PMLSM.
- You can use the “PMLSM” block and modify it to a two-phase configuration. This block usually represents a three-phase machine but by adjusting the parameters and simplifying you can create a two-phase equivalent.
- Customize the electrical and mechanical parameters of the motor such as the stator resistance, inductance, back EMF constant and the number of pole pairs.
Please refer to the following documentations to read more about these:
