Hello
i am doing my final year individual project regarding linear motor control and drive circuit.
but i have problem in the simulation of the drive circuit using simulink.
my linear motor has 6 ports like 3 positive and 3 negative and i just want to know how can i implement in the simulink. i saerched in the simulink library but i couldnt find one with these structures. I am using a H bridge MOSFET circuit for 1 phase consisting of 1 positive and 1 negative of the motor and similarly for other 2 phases.
so how can i develop a dc linear motor with 3 positives and 3 negatives

Hi Vishnu ,
Developing a simulation model for your linear motor with 3 positive and 3 negative ports in Simulink can be achieved by customizing the H-bridge circuit.
Here's an outline,
  • Utilize H-bridge blocks available in Simulink( you can also create custom H-Bridge blocks), and customize them to have 3 positive and 3 negative ports for each phase of the motor
  • Integrate a DC motor model into the circuit. Simulink offers various motor models that you can use for simulation purposes.
  • Arrange the ports of the H-bridge blocks to match the configuration of your motor. You may need to use multiple H-bridge blocks for each phase to accommodate the 3 positive and 3 negative ports.
  • Ensure that the connections maintain the correct polarity and configuration according to your motor's specifications
  • Configure the parameters of the H-bridge blocks, such as MOSFET characteristics, switching frequency, and motor parameters, to accurately represent your system.
  • Define appropriate input signals (such as desired motor position or speed) and simulate the system over the desired time period.
You can also refer to the below documentation links for more information,
Hope this helps!
