I have manually designed a motor in MAxwell 3d. I was wondering if I can run my motor as a generator by specifying the speed and get output voltage at the terminals?

of course´╝ü

How to do that? I am not talking about the RMxprt preset design

Hi @umozumder You can set up everything like the motor.
For excitation, you can select it as external and define the external circuit with a load (say resistance) across the winding phases.

Hi Navya
I was trying to set up an external circuit. unfortunately, I am not finding the option for the ground.

My primary and foremost concern is how can I define the speed for my generator? Cause I need to provide certain voltage and frequency in the terminals which totally depending on the generator speed.

Thanks

Just following up on my question. Thanks for your answer about finding the ground.

I am trying to set a speed (RPM) for my machine(trying to form a generator) so that I can get an output voltage with a specific frequency in the coil terminals. Is that possible with the MAxwell 3D manual design?

Thanks

Yes Create a band object and assign band (for the rotor).
Under motion setup in project manager window define the speed.
It is the same as for motor.
Refer to some inbuilt examples/help file if you have questions on how to define and motion setup.

Thanks a bunch. That worked. I am getting an error saying '' error in making mesh in the band object'" and the simulation is terminating. Any thought on that would be appreciated

Create band object using Polyhedron,with around 120 segments, and not using a cylinder.
If that didn't work. Create another dummy polyhedron object between band and stator

That worked, thanks a lot.
When I am trying to simulate I am getting this error. I am not sure whats I am doing wrong.
